Introduction
IntroductionThe “Activity Book for Teachers: Five Keys to Safer Food” is an educational tool to facilitate the teaching of the contents of the “Five Keys to Safer Food” manual to elementary school students.
This educational manual constitutes part of “The Adaptation and Validation of the WHO Five Keys to Safer Food Manual for Elementary Schools in Gua-temala” project, coordinated by the Pan American Health Organization (PAHO). This project is a component of the Global School Health Initiative promoted by the World Health Organization (WHO), Pan American Health Organization (PAHO) and the Institute of Nutrition of Central America and Panamá (INCAP).
The purpose of this manual is to provide teachers with resource material to help students understand the five keys to safer food in an entertaining, participative and dynamic way. It will help students incorporate this knowledge into their daily life, to promote behavioral changes in both the students and their families, and improve their health and well being.
The manual includes activities with worksheets aimed for two specific grade groupings in elementary schools: one group is from first to third grade and the second, fourth to sixth grade. Each activity includes information about the purpose of the activity, lecture that should be given before starting the activity, materials needed, methods, and discussion questions so students can reflect on what they have learned.
The activities are designed so that through games, demonstrations and experiments students can put into practice what they have learned, evaluate and reinforce their knowledge and visualize the various concepts being taught. Teachers can select the activities which best meet the needs of their class and adapt them based on their students´ abilities and resources available.
WE HOPE THIS ACTIVITY BOOK IS A USEFUL REFERENCE FOR YOU IN YOUR CLASSROOM!!

Introduction
Activity # 1How do germs multiply?1
Level: 4th to 6th grade
Purpose:
For students to:
• Visualize how germs multiply.
• Identify the ideal places and conditions for germs to multiply.
Lecture before the activity:
Teachers should explain that:
• Germs are living organisms that need warmth, air, humidity and food to live, just like humans do. Without this, they cannot multiply since these are fundamental conditions for their growth and multiplication.
• If high temperatures are sustained over a long period of time (such as when water is boiled) germs are killed. If temperatures are really cold germs may not die but they will not be able to multiply.
• Germs find a warm and humid environment ideal for
their multiplication in foods such as milk, cheese, cream, mayonnaise, meat (especially raw meats) and cooked
food if they are not stored properly.
Methods:
1. Divide the class into small groups (a maximum of 5 students per group).

2. Give each group a sheet of flipchart paper and ask them to fold it to form 8 squares.
3. Tell students that each member
of their group should draw a food that bacteria would find ideal for their multiplication in one of the squares. Each student should make their drawing in a different square on the sheet of paper. Examples of foods include milk, fresh cheese, meat, cream, ham, chicken, etc.
4. Give each group a container filled with grains and explain to the students that each grain represents a germ.
5. Once the students have finished their drawings, ask for a representative from each group to place the first “germ” on the first square on the upper left-hand side of the sheet of paper.
6. Another member of the group should multiply the first germ by two and put that amount of grains on the second square, and follow the procedure des-cribe below: on the first square put 1 grain, on the second squa-re 2, on the third 4, on the fourth 8, on the fifth 16 and so forth until
all the squares have been used up.
All group members should par-ticipate at least once, placing the right amount of grains on the corresponding square.
Amount of grains that should be placed on each square:
1 1 X 2 = 2 2 X 2 = 4 4 X 2 = 8
8 X 2 = 16 16 X 2 = 32 32 X 2= 64 64 X 2= 132
7. After placing the grains on all of the squares, students should glue the grains onto the paper and present to their classmates.

Introduction
8. When finished, ask the discussion questions. Ask students to raise their hands if they know the answer.
Discussion questions:
• What happened to the first
germ?
• Why did this happen?
• What should be done to
prevent this from happening?
• Where are ideal places for
germs to multiply?

Activity # 2How are germs spread?2 Level: 1st to 6th grade
Purpose:
For students to:
• Identify their hands as a source of contamination.
• Understand the importance of washing their hands to prevent contamination of foods and foodborne diseases.
• Observe that germs can multiply rapidly on their hands and other places.
Lecture before the activity:
Teachers should:
• Talk about the importance of washing your hands in order to prevent the contamination of food, utensils and areas where
food is prepared.
• Point out that even though germs cannot be seen with the naked eye, if we do not wash our hands properly germs can multiply on them. Hands are also a way for germs to contaminate other surfaces, putting our health
at risk. Clothes are another vehicle for the transportation of germs; therefore, it is very important to wash them
regularly.

Introduction
• Emphasize that with proper personal hygiene (taking a bath, washing your hands and clothes and brushing your teeth regularly) we can help prevent foodborne diseases.
• Explain that germs multiply easily and if we don’t do something to prevent this from happening they can contaminate the areas where we prepare food and the food we eat.
Methods:*
1. Ask students to go out to the playground.
2. Randomly choose a student and tell him/her to fill his/her hands with flour or plaster. This student should chase his/her classmates and touch them with his/her hands that are covered in flour, therefore “infecting” the other student.
3. Tell students that they have a certain amount of time (for example 20 minutes) and that during this time, the student that was chosen to “infect” the others
will try and touch as many other students as possible.
4. When a student is touched, he/she must stand still since he/she is now “infected” (he/she will be stained with flour).
5. When the students return to the classroom, count how many children were “infected” and explain to them that the flour or plaster represent germs.
6. Ask the discussion questions.
* Another option for showing how germs move from one place to another is with a sponge and some washable paint (the paint represents the germs). Paint the sponge and pass it from one student to another until every student has had a chance to touch it. Afterwards, ask the discussion questions.
Discussion questions:
• What happened during the
activity?
• What was the vehicle used by the
germs to spread and contami-
nate others?
• What should we do to prevent the
spread of germs and contamina-
tion? Explain with details.
• What other vehicles or means
are used by germs to spread (ask
the students to give some exam-
ples)?

Activity # 3Installing a SODIS system in our schoolLevel: 1st to 6th grade
Purpose:
For students to:
• Learn about the SODIS method.
Lecture before the activity:
Teachers should explain that:
• Untreated water may be conta-minated with dangerous germs and should therefore be treated (treatment methods include: boi-ling water, adding chlorine or applying the SODIS method).
• That water that does not have any taste, color, or smell may seem safe, but if it has not been treated, it can cause foodborne diseases.
• Water used for drinking, preparing food or cleaning utensils must be safe in order to avoid getting a foodborne sickness.
• The SODIS method is a simple way to purify water and uses readily accessible materials such as sunlight and plastic bottles.
• If water is exposed to sunlight for a long enough period of time the ultraviolet rays and the rise in the

temperature of the water generated by the sunlight, destroys the dangerous germs found in the water, therefore disinfecting it.
Methods:*
1. Ask students to bring a transpar-ent 2 lt. plastic bottle with a cap to school on the day you have decided to perform this activity.
2. Give each student a small amount of dish detergent and ask them to wash their bottle.
3. Ask students to fill their bottles with clear water (not cloudy) and tightly close with the cap.
4. Give each student some mask-ing tape and ask them to write their name on the tape with a marker. Tell them to put the tape
on the cap of the bottle. They should not place the tape on the bottle because the tape could block the sunlight from destroying the germs in the water.
5. Ask students to place their plastic bottles in a place where direct sunlight will shine on them for at least 6 hours if it is a clear day**
• From 9:00 to 15:00 hrs. • Or for 2 consecutive days if it is cloudy.
6. When the bottles have been under the sun for the specified amount of time, ask students to bring their bottles into the classroom to let them cool. When the water is no longer warm, students can drink their safe water.
* Go to page 19 in the Content Manual to see an illustration of how to treat water using SODIS.
** We suggest starting this activity in the morning so that the bottles are exposed to sunlight for at least 6 hours. If the school day is less than 6 hours long, place the bottles in the sunlight for two days (if the day is sunny) and at the end of the second day, remove them from the sunlight.

Key #1
7. When the activity has ended, give each student a sheet of paper and ask them to draw the different steps of the SODIS method.
8. Ask four students to come to the front of the class. Each one should draw one of the steps of this water treatment method on the chalkboard.
9. Ask students in your class to take
the diagram they drew home so that they can explain the SODIS method to their parents.
Discussion questions:
• How does the SODIS method
function? How does it kill
germs?
• After applying the SODIS
method, either at school or
at home, how should we
properly store this safe
water?
• What other purification
method can we use to make
sure the water we drink is
safe?
• What can we do at our
school to make sure there is
safe water to drink?

Use safe water and food for your consumption
Activity # 4Which are safe water sources?Level: 1st to 3rd grade
Purpose:
For students to:
• Identify which are safe water sources, and which are unsafe to use for preparing food and for drinking.
Lecture before the activity:
Teachers should reinforce:
• The concept of “safe water and food”, giving examples of safe water sources as well as unsafe water sources.
• That water may be contaminated with dangerous germs if it has not been treated (for example boiling water, using chlorine or the SODIS method).
• That water that does not have any taste, color, or smell may seem safe, but if it has not been treated, it can cause
foodborne diseases.
• That in order to prevent foodborne diseases water used for drinking, preparing food and cleaning utensils must be safe.

Key #1
• That containers used for stor-ing drinking water or water that will be used for preparing food should have certain characteris-tics to avoid contamination. This container should have a lid or be covered with a clean cloth, placed in a high place (such as a table) so it is out of reach of pets.
• That when safe water is stored in a container that is not covered, it can become contaminated by dust or insects. Also water
can become contaminated by introducing contaminated utensils into it.
Methods:
1. Give each student the work-sheet “Which are safe water sources?”
2. Read the instructions aloud or ask a student to do it. Ask stu-dents if they have any questions about the instructions.
3. Give the students 20 minutes to complete the worksheet.
• For students that know how to write (2nd and 3rd grade), ask them to write a sentence on the back of the sheet about how each water source that was marked as unsafe could be made safe.
4. Ask each student to read aloud one of the sentences he/she wrote.
5. Then, ask them to hand in the completed worksheet.
6. Ask the discussion questions, inviting students to participate by raising their hand when they know the answer.

Use safe water and food for your consumption
Discussion questions:
• Why do you consider the illustrations that you marked with an “X”
unsafe water sources?
• How could these unsafe water sources become safe?
• What is being done at your school or in your house to ensure that the
water you drink is safe?
• What can you do at home so that animals do not have
access to the water used for drinking or preparing
food? What can you do at your school?

Level: 1st to 4th grade*
Purpose:
For students to:
• Visualize the amount of germs that could be found on their hands after touching specific foods and doing specific activi-ties at school and home.
• Understand the importance of washing their hands properly to eliminate germs that could make them sick.
Lecture before the activity:
Teachers should:
• Explain that hands frequently transport germs from one place to another; therefore, it is important to wash your hands before eating and after handling certain objects or foods.
* For 5th and 6th grade, use the illustrations as introductory material to
explain how germs use hands as a form of transportation.

• Emphasize that washing your hands properly can help prevent foodborne diseases.
• Reinforce that some raw foods, for example chicken and beef may contain dangerous germs; and therefore, it is very impor-tant to wash your hands after handling these foods.
• Reiterate the importance of washing your hands properly
with safe water and soap for at least 20 seconds (the teacher can use a popular song to measure this time).
Methods:
1. Tape the six illustrations of the hands with germs on the chalkboard or wall.
2. Ask students to take a piece of blank paper, fold it in half, cut it and share the other half with a classmate.
3. Explain the instructions for the game:
• For 3rd and 4th grade:
a. Explain that each illustration represents a different situa-tion (i.e. a person’s hands af-ter handling raw chicken) and that the black spots on the il-lustrations represent germs.
b. The teacher should read aloud the story on the following page. This story presents different scenarios where hands are being contaminated by germs.
Students have to guess which illustration, from those on the chalkboard, corresponds to each scenario. Tell students to write the letter of the corresponding illustration on their piece of paper.

Key #2
“Once upon a time there was a boy named John who loved to have his photo taken. But one day when he was taking photos of his hands, they turned out different… the photos were magical, he was able to see the germs on his hands after doing different activities”.
The different scenarios when the magical photos were taken of
John’s hands are described below…
- John was in such a hurry to go to his friend Mary’s house to play that he did not wash his hands properly. Which illustration do you think represents this situation? (Answer: Illustration C)
- While helping his mother prepare food, John picked up a piece of raw chicken. Which illustration do you think represents this situation? (Answer: Illustration E)
- John wanted to help clean the kitchen, but he got confused and instead of picking up a clean cloth, he picked up a dirty one. Which illustration do you think represents this situation?
(Answer: Illustration D)
- Before having dinner, John went to the bathroom and afterwards washed his hands with soap and water for 20 seconds. Which illustration do you think represents this situation?
(Answer: Illustration A)
- John was tossing around a ball with his friends when he suddenly had to go to the bathroom. After going to the bathroom, he went back to playing without washing his hands because he did not want to miss any more of the game. Which illustration do you think represents this situation? (Answer: Illustration F)
- John went with his mother to the supermarket. When passing by the meat department, he became curious and picked up a piece of meat to feel its texture. Which illustration do you think represents this situation?
(Answer: Illustration B)

c. At the end of the activity, the teacher should tell the students the correct answers. The correct answers are: “Hands after…”
• Washing them thoroughly with soap for 20 seconds
(Illustration A)• Handling raw meat (Illustration B)• Washing them improperly*
(Illustration C)• Handling a dirty cloth (Illustration D)• Handling raw chicken (Illustration E)• Going to the bathroom (Illustration F)
d. Ask the discussion questions.
• For 1st and 2nd grade:
a. The teacher should tell the story on page 20 which presents different scenarios where hands are being contaminated by germs.
b. While telling the story, show students the corresponding illustration, explaining each of them.
c. Afterwards, hand out a piece of blank paper and ask students to
draw 2 hands (one on each side of the paper) that represent the following:
• A hand that has been thoroughly washed and therefore is FREE OF GERMS,
• A hand that is dirty and therefore FULL OF GERMS
d. Finish off the activity by asking students to hold up their drawing which best shows what their
hand would look like after playing with their pet (dog, cat, etc.)
Discussion questions:
• Which illustration (hand) has the
most germs?
• Which illustration (hand) has the
least germs?
• What other activities would
make your hands look like
illustrations B-F (i.e. with lots of
germs)?
• Do you think there are germs on
your hands right now? Why or
why not?
• What can you do to avoid
having germs on your hands?* Explain to students that people often forget to wash their thumbs when washing their hands.

Activity # 7Wash your hands with soap and water 4
Level: 1st to 6th grade
Purpose:
For students to:
• Pay attention to their personal hygiene.
• Identify hands as a source of contamination and a vehicle for spreading germs.
• Learn how to properly wash their hands.
Lecture before the activity:
Teachers should:
• Discuss the importance of washing your hands, the most important times to wash your hands (before and after what
types of activities) and the proper technique; emphasizing the importance of rubbing your hands together for 20 seconds.
• Emphasize the fact that even though our hands might appear clean to the naked eye, we may have germs
on our hands that we can’t see and that could make us sick.

• Emphasize that germs are so small that we cannot see them with our naked eye.
Methods:
1. Ask for three volunteers to help with this activity.
2. Ask these volunteers to rub their hands together with two drops of oil or vaseline.
3. They should then cover their hands with cinnamon powder or sand. The cinnamon / sand represents the germs.
4. Afterwards, the volunteers should touch some kitchen items such as utensils, a glass, a plate, etc. with their dirty hands (so that they can see how germs transfer from one place to another).
5. Ask the three students to wash their hands as described below:
- Student #1: wash his/her hands with just water
- Student #2: wash his/her hands with water and soap for 3 seconds
- Student #3: wash his/her hands with water and soap for 20 seconds
6. Ask the rest of the class to count to 20 aloud while student #3 is washing his/her hands to help him/her know when he/she should stop washing his/her hands. Instead of counting the class can also sing a song that lasts for the 20 seconds (i.e. “Happy Birthday”).
7. After washing their hands, the three students should show their hands to their classmates.
8. Ask the discussion questions.
Discussion questions:
• How can we remove germs from
our hands?
• What happened when the volun-
teers touched the kitchen items?
Would you eat with the utensils?
• What happens when we wash
our hands with only water?
• What happens when we wash
our hands with water and soap
and we rub our hands together
for 3 seconds?
• What happens when we wash
our hands for 20 seconds?

Activity # 8What should I do when preparing food?Level: 1st to 3rd grade
Purpose:
For students to:
• Understand how to properly prepare food so that it doesn’t become contaminated with germs.
• Reinforce concepts learned in Key #2: Keep clean.
Lecture before the activity:
Teachers should:
• Explain that when students are helping prepare food at school or at home, utensils used to prepare and serve food need to be handled properly.
• Explain that if our hands are not clean, we could contaminate the surfaces and utensils used in food preparation; therefore, it is important
to be careful when handling dishes, silverware, glasses, etc.
• Emphasize the importance of keeping animals and pests away from the areas where food is prepared to avoid contamination.
• Emphasize that certain sicknesses caused by germs can be prevented if we learn how to keep the areas where we prepare food clean.

Separate raw meat, poultry andseafood from other foods
Methods:
1. Divide students in small groups.
2. Dampen the two sponges with water. One of the sponges represents a piece of “cooked chicken/meat” and should be kept away from the other sponge that represents a piece of “raw chicken/meat”.
3. Paint one of the sponges with the red paint. Use enough paint to cover both sides of the sponge (the paint represents the blood of the raw chicken/meat that is contaminated with dangerous germs).
4. Place the painted sponge (raw chicken/meat) on the cutting board and cut it in half with the knife.
5. Place the two halves on the plate. Do not wash the cutting board, knife or your hands.
6. Cut the piece of lettuce in half using the same cutting board and knife.
7. Cut the sponge without paint (cooked chicken/meat) in half on the same cutting board with the same knife (without washing them).
8. Place the two halves of the sponge that represent the “cooked chicken/meat” on the same plate where the “raw chicken/meat” is.
9. Observe the transfer of the paint to the other objects.
10. Ask the discussion questions, inviting students to participate by raising their hand when they know the answer.
Discussion questions:
• What happened when the
cooked chicken/meat was
placed on the same plate as the
raw chicken/meat?
• What would happen if we ate

Purpose:
For students to:
• Understand that heat kills dangerous germs that can be found in food, making the food safe to eat.
• Identify foods that should be thoroughly cooked.
Lecture before the activity:
Teachers should:
• Explain that there are certain foods that are more likely to contain dangerous germs, such as raw meat, chicken, eggs and milk. These foods should be cooked thoroughly at a high temperature in order to
kill any germs they may have, making them safe to eat.
• Emphasize that these foods can contaminate other foods that are eaten raw (i.e. fruits and vegetables) or are already prepared. This contamination may produce foodborne diseases.
• Remind students that certain foods such as meat, milk and eggs and water are ideal for the multiplication
of germs; therefore, it is important to boil or cook them

Independence Day Celebration at my school
Instructions: A story is presented below. Read it thoroughly, paying attention to the details and underline the sentences where errors were made that could cause the contamination of the food.
One week before, the students began preparing the food: plantains with cream, ham and cheese sandwiches, tortillas with roasted meat, potato salad with mayonnaise and various desserts including cream filled donuts and different flavored cakes …mmm, delicious!!
The 1st was in charge of bringing the ham and cheese sandwiches with butter which they brought prepared the day before the celebration. But John forgot to store the sandwiches in a cold place and instead left them on the teacher’s desk, where the sun shone on them the whole afternoon.
LET’S CELEBRATE INDEPENDENCE DAY! At school everyone was talking about the Independence Day Celebration, about the planning of the fair, the food stands and the dances were going to be prepared, who would participate, and what each class would do to celebrate the day.
The principal distributed the list about which class would bring which type of foods to sell at the Fair.
The potato salad with mayonnaise was delicious, but warm because it was a sunny day. Since there were not enough tables, the potato salad was placed on the floor. Fruits such as mango were also being sold and cut with the same knife that was used to cut the raw chicken. Everything was going well but then suddenly everyone started feeling bad and having stomach pains, fever and vomiting. Such a beautiful day which unfortunetly ended badly.
Worksheet
A delicious chicken with vegetables was also being sold at the fair. Such a large amount was needed and the mothers had so much to do that they prepared the dish the day before. On the day of the celebration, they realized they had forgotten to add the CHICKEN.
The students were so anxious to eat, the mothers added the raw chicken and only let it boil a few seconds.
On the day of the fair, the 6th class brought the meat to barbecue. They gave the meat to their teacher to BBQ. There was such a long line and all the students were so hungry that the cooks started handing out the tortillas with meat that was still pink in the inside and really juicy!
The 2nd class had a stand where they where selling plantains with cream. It was so hot out that the cream melted. The food smelled so good that it started attracting flies.

Key #4
Questions / Statements Answers Explanations
Is it true that the inside of meat and chicken that you are going to eat should not be pink?
YES
Meat and chicken are thoroughly cooked when their juices are clear and the inside is no longer pink
Is it true that only the outside of chicken may contain dangerous germs?
NOBoth the outside and the centre can have germs
If you boil soup for thirty seconds will all germs be killed?
NOYou need to boiled it for 5 minutes
Is it possible to see germs with the naked eye?
NONo, we cannot, we need a microscope
Are nausea or vomiting symptoms of foodborne diseases caused by dangerous germs found in food?
YES
Should you drink water when you have diarrhea or stomach problems?
YESYes, to rehydrate our body. An oral rehydration solution can also be drunk.
Washing your hands for 10 seconds is enough time?
NOYou should wash them for at least 20 seconds
It is alright to cut an orange with the same knife that you used to cut raw meat?
NO
A different knife should be used for each, or you should wash the knife with water and soap before cutting the orange
Is there a difference between the terms cleaning and disinfecting? Explain it.
YES
Cleaning wipes away dirt, crumbs, grease or other substances; disinfecting kills germs completely
Are rats an example of a pests? YESOther examples are: cockroaches, flies, ants, etc.
Is it true that fish does not have to be cooked thoroughly since it does not contain many germs?
NO
Fish, as well as poultry, seafood and meat (beef) can have many dangerous germs; therefore, it is important to cook them thoroughly until their juices run clear

Keep food at safe temperatures
Activity # 14Where should we keep food?
Level: 1st to 3rd grade
Purpose:
For students to:
• Review the concept of keep-ing food at safe temperatures to avoid the multiplication of dan-gerous germs.
• Identify foods that should be kept in a cold place and those that can be left at room temper-ature (in a cupboard).
• Understand that germs cannot easily multiply in cold tempera-tures.
Lecture before the activity:
Teachers should:
• Discuss the importance of keeping certain foods at very cold temperatures and that foods can be kept safe if we properly control the temperatures that they are kept in.
• Emphasize that at very hot temperatures, i.e. when liquids are boiled, germs die, therefore making the food
safe to eat. Also emphasize that germs do not multiply in very cold temperatures, therefore keeping food safe.

Key #5
• Explain that when students are helping prepare food at home or at school, it is important to remember which foods need to be stored in a cold place (i.e. fresh milk) and which not (i.e. raw vegetables such as carrots).
Methods:
1. Using the masking tape, tape the illustrations of the ice and cupboard on two different walls in the classroom.* This activity can also be performed outside the classroom (i.e. in the play-ground).
2. Explain to students that you are going to say a food and that they should decide where that food should be stored and then run towards the corresponding illustration as described below:
• If the food mentioned should be stored in a cold place (such as fresh milk), students should run to the wall where the illustration of ice is taped.
• If the food mentioned can be stored in a cupboard, stu-
dents should run to the wall where the illustration of the cupboard is taped.
3. After students have run to the illustration they believe is correct, discuss their decision with them.
4. Repeat the activity with another food.
Examples of foods:
Fresh cheese (cold) Cooked chicken (cold) Tomatoes (cupboard) Cream (cold) Cooked pork (cold) Raw chicken (cold) Raw carrots (cupboard) Dried or uncooked beans
(cupboard) Fresh milk (cold) Powdered milk (cupboard) Dried oatmeal (cupboard) Mangos (cupboard) Prepared oatmeal (porridge)
(cold) Raw beef (cold) Papaya (cupboard) Oranges (cupboard) Uncooked rice (cupboard) Tortillas from yesterday (cold)
* Make sure that the students desks are moved to one side of the classroom so that students have enough room to run to the walls.

Keep food at safe temperatures
• Explain that certain foods (such as perishable foods) have the perfect conditions for germs to grow and multiply and therefore it is important to cook them thoroughly.
• Emphasize that foods such as
raw carrots (or other vegetables) do not spoil easily, but before eating them they should be washed with safe water in order to kill any germs they might contain.
Methods:
1. Fill two glasses with the same amount of milk.
2. Pour the milk from one of the glasses into a pot and place the pot on the stove. Boil the milk for 5 minutes.
3. After boiling the milk, cover the pot with a lid and place the pot inside the container with water.
4. Leave the glass with the milk that has not been boiled uncovered for the rest of the day and over-night.
5. Ask students to leave the carrot (or another vegetable) beside the glass of milk, as well as the boiled milk.
6. Two days later, observe the changes that happened in the unboiled milk in the glass and the milk in the pot, as well as the carrot.
7. Ask the discussion questions.
Discussion questions:
• What should we do with perish-
able foods? How should they be
stored?
• What about non-perishable
foods? Are they free of germs?
• What happened to the glass of
unboiled milk that was left uncov-

Activity # 16Yeast balloons8
Level: 3rd to 6th grade
Purpose:
For students to:
• Understand that foods kept at safe temperatures (very cold or very hot) helps protect from germ spreading.
• Visualize the multiplication of germs at certain temperatures.
Lecture before the activity:
Teachers should:
• Discuss the importance of keeping food at safe temperatures (very cold / very hot), since proper temperature control helps keep food safe.
• Emphasize that germs die in very hot temperatures
(such as in boiling water), making food safe to eat.
• Review the concept that at very cold temperatures germs do not find an environment in which they can multiply, keeping food safe. On the other hand, germs
find the perfect environment to survive and multiply in warm temperatures (room temperature).

Keep food at safe temperatures
• Reinforce the four conditions germs need in order to grow and spread (humidity, air, warmth and food).
• Explain that yeast contains ben-eficial germs that help bread grow, but like other germs, it needs a certain type of environ-ment to grow. Yeast is a good example for observing the be-havior of germs.
Methods:
1. Using the tape and marker, label one washbasin “cold bath” and the other “warm bath”.
2. In the third washbasin, place half a liter of room temperature water. Add the sugar and stir
until dissolved. Then add the package of yeast, mixing it slowly into the sugar mixture.
3. Divide the sugar and yeast solution into two equal parts and pour into the two plastic or glass bottles.
4. Inflate the balloons, and then de-flate them to help stretch them out. Place one balloon over the opening of each bottle.
5. Place a bottle upright in each of the labeled washbasins.
6. Add hot water to the basin labeled “warm bath”. Add just enough water to cover the sugar and yeast solution in the bottle.
7. Follow the same procedure, adding the ice water to the basin labeled “cold bath”.
8. Observe and write down what happens after 5 min., 30 min. and 1 hour.
9. The teacher should explain what is happening:
• The microorganisms found in yeast (which are good germs) behave differently at certain temperatures.
• The germs do not multiply as fast in the yeast solution placed in the cold water be-cause this is not the perfect environment for them.
• But in the warm water, the germs in the yeast solution, find a perfect environment for them to grow and spread. These growing germs
52
Key #5
produce gases, making the balloon inflate. The sugar in the solution acts as food for the germs. Therefore, in the warm water the yeast germs find both food and a perfect environment to multiply rapidly.
Discussion questions:
• What happened to the balloon in the “warm bath”?
• What happened to the balloon in the “cold bath”?
• In what way do yeast and bad germs that could be found in food act
the same?
• If yeast were a dangerous germ, what would happen if we were to
store it in a warm environment?
• If yeast were a dangerous germ, what would happen if we were to
store it in a cold environment?
• What effect did the cold temperature of the ice water have on the
yeast?

Purpose:
For students to:
• Visualize different ways they can make their school a healthier envi-ronment.
• Review concepts learned about the prevention of foodborne sick-nesses.
Lecture before the activity:
Teachers should:
• Review what can be done to prevent foodborne sicknesses; i.e. eating healthy, caring for their
personal hygiene and washing fruits and vegetables with safe water.
• Remind students that the ingredients and water used in the preparation of food may be contamina-ted with germs. It is therefore important to take pre-ventive measures to avoid putting our health at risk.
• Ask students what they do at school and at home to help prevent foodborne sicknesses. What do their tea-
chers, parents, brothers, sisters and other relatives do?

Independence Day Celebration at my school
Instructions: A story is presented below. Read it thoroughly, paying attention to the details and underline the sentences where errors were made that could cause the contamination of the food.
One week before, the students began preparing the food: plantains with cream, ham and cheese sandwiches, tortillas with roasted meat, potato salad with mayonnaise and various desserts including cream filled donuts and different flavored cakes …mmm, delicious!!
The 1st was in charge of bringing the ham and cheese sandwiches with butter which they brought prepared the day before the celebration. But John forgot to store the sandwiches in a cold place and instead left them on the teacher’s desk, where the sun shone on them the whole afternoon.
LET’S CELEBRATE INDEPENDENCE DAY! At school everyone was talking about the Independence Day Celebration, about the planning of the fair, the food stands and the dances were going to be prepared, who would participate, and what each class would do to celebrate the day.
The principal distributed the list about which class would bring which type of foods to sell at the Fair.
The potato salad with mayonnaise was delicious, but warm because it was a sunny day. Since there were not enough tables, the potato salad was placed on the floor. Fruits such as mango were also being sold and cut with the same knife that was used to cut the raw chicken. Everything was going well but then suddenly everyone started feeling bad and having stomach pains, fever and vomiting. Such a beautiful day which unfortunetly ended badly.
A delicious chicken with vegetables was also being sold at the fair. Such a large amount was needed and the mothers had so much to do that they prepared the dish the day before. On the day of the celebration, they realized they had forgotten to add the CHICKEN.
The students were so anxious to eat, the mothers added the raw chicken and only let it boil a few seconds.
On the day of the fair, the 6th class brought the meat to barbecue. They gave the meat to their teacher to BBQ. There was such a long line and all the students were so hungry that the cooks started handing out the tortillas with meat that was still pink in the inside and really juicy!
The 2nd class had a stand where they where selling plantains with cream. It was so hot out that the cream melted. The food smelled so good that it started attracting flies.
