Kesler Science Station Lab – Symbiosis – Teacher Directions
Explore It! – I will spend much of my time at this station making sure students are understanding the concepts. You should be available to guide and check the diagrams the students are building. This is great time to mention the biological and geological symbiosis.
Illustrate It! – Make sure to include colored pencils or crayons at this station. I have included 3 examples if you want to place those out for students to use.
Read It! – Print several different copies (I use 6) of the reading passage so that multiple students can read at different paces
Watch It! – The video is on YouTube and my Google drive. Use YouTube unless your school is blocked. The original link is

Read It! Station DirectionsEach member of the group will read the passage and answer the questions from the task cards on the lab sheet in the Read It! section.
It is important to remember that the answers will come directly from the reading passage.
Symbiosis
Species interact every day. That interaction is a vital part of how organisms develop and change over time. When you study species, it is important to watch the way they interact with their surroundings. You probably remember something about the predator/prey relationship as well as competition among organisms. This article will focus on symbiotic relations of which there are three main types: mutualism, commensalism, and parasitism.
The heart of mutualism is that two species live together in harmony. Both species receive an advantage by working with the other. It helps them both survive. An example would be the bees and flowers. The bee gets nutrition from the flower, while the flower is pollinated. Rescue dogs are another example of mutualism. The masters take care of the dogs and the dogs learn how to save people. Everyone benefits in the end.
Sometimes one species can benefit from a relationship and not hurt the other. That relationshipdescribes commensalism. A wren and a cactus are an example. The wren uses the cactus as a shelter, but the cactus isn’t harmed in anyway. One plant gets a place to live and the other doesn't care and is not hurt.
There's a special type of symbiotic relationship called parasitism. Think about all the creepy crawlies like fleas, viruses, and mosquitoes. They all feed off a host, not killing it right away but slowly sucking the life out of it. Parasites help no one but themselves.

Research It! Station DirectionsEach member of the group will go to the website listed on task card #1
Complete the task cards in order.
Every student will answer the questions from the task cards on the lab sheet in the Research It! section.
1. Go tohttps://goo.gl/MLrTCF
Read the question and answer on the first page. Then explore the 3 links under “Keep Learning”.
Find two different examples for each of the types of symbiosis that have not already been presented in the lab. Describe them on your lab sheet.
Explore It! Station Directions
One member of the group will read the task cards in order.The group will be responsible for completing each of the tasks that are being read.
Each member of the group will then write their conclusions down on the lab sheet in the Explore It! section.
Symbiosis is the relationship between organisms. There are three types of symbiosis: Commensalism, Mutualism, and Parasitism.
Look at each of the picture cards and answer the questions found at the bottom of each card. Write your answers on your lab sheet.

Spotted Breasted Oriole and Bronzed Cowbird
The cowbird lays eggs in the nest of the oriole. The orioles feed and raise the cowbird’s young.
1. What is the advantage and disadvantage of this relationship to each bird?
2. What would happen to the cowbird population if the oriole population decreased?
3. What type of symbiosis is this?
Explore It! Station Directions
Mesquite Tree and Mistletoe
Mistletoe is a green plant that can make its own food, but also derives food from the mesquite tree on which it lives. In this way mistletoe is able to steal water and valuable minerals from the tree.
1. What is the advantage and disadvantage of this relationship to each organism?
2. What would happen to the mistletoe population if mesquite trees increase in number?
3. What type of symbiosis is this?

Ocotillo and Hummingbird
An ocotillo is a plant on which hummingbirds like to feed. While getting the nectar from the flowers as food, the humming bird cross- pollinates the flowers to help the plant reproduce.
1. What is the advantage and disadvantage of this relationship to each organism?
2. What would happen to the hummingbird population if ocotillo decreases in number?
3. What type of symbiosis is this?

Cactus Wren and Cholla Cactus
The Cactus Wren builds its nest in the Cholla Cactus, which provides it protection. The cactus is not harmed by the wren living there.
1. What is the advantage and disadvantage of this relationship to each organism?
2. What would happen to the wren if the cactus decreases in number?
3. What type of symbiosis is this?
Illustrate It! Station DirectionsEach member of the group will draw a quick sketch on the lab sheet that shows they understand the concept being taught.
Use the colored pencils and markers that are provided.
The directions for the sketch are provided on the task card at the table.
Illustrate It! Station DirectionsUse your imagination and draw an example of one of the three types of symbiosis. This can be an interaction between two “real” animals, or you can create two imaginary animals. See if someone at your station can guess what type of symbiosis you are trying to represent.
Organize It! Station DirectionsIt is recommended that you have completed at least twoof the following stations before working at this station.-Read It!-Explore It!-Watch It!-Research It!
Each group will organize the examples under the correct heading. Write C, M, or P on your lab sheet for each example. Have your teacher sign off your Organize it section.
Please mix up the cards again before the next group arrives at this station.
Commensalism
MutualismParasitism
1. Golden jackals no longer in a pack will trail a tiger, so they can feed on what the tiger kills.
2. Humans utilize the oxygen that plants give off then exhale carbon dioxide. Plants use the carbon dioxide to create that oxygen that the humans need.
3. Mites will attach to wasps, flies or beetles for transportation.
4. Tapeworms damage their hosts because they eat partially digested food thus depriving the host of some food and nourishment.
5. Malaria is a life-threatening blood disease caused by parasites that are transmitted to humans through the bite of the Anopheles mosquito.
6. Hermit crabs have to find shells for shelter and use various snail shells. These shells are available because the snail has died.
7. Aphids eat sap from plants, causing a decline in plant health.
8. The shrimp digs a burrow into the sand and a goby fish moves in with it. Because the shrimp is almost blind, the goby fish will touch the shrimp when a predator is near.
9. Dogs supply protection and companionship and humans provide food and shelter.
