May 19, 2020 Unit 4 – Organisms and Interdependence

Essential Question: How does an ecosystem function?

Criteria for Success

•Identify examples of living & non living things

•Develop a criteria for classifying things as living or nonliving

•Identify characteristics that all living things share

2- Explain your thinking. What “rule” or reasoning did you use to

decide if something on the list could be considered living?

Traits of All

Living Things

I- Any living thing is called an organism.

II

III -Even though all organisms vary, they all share some of the same

traits/ characteristics. All living things:

All living things need a proper place to live, water, air and some

type of food source.

Let’s Watch the Video Clip-

What traits do all living things share?????

Tool Box 50 – Continued

All Living Things …….

A) are organized and made up of cells (the smallest unit of an

organism that carries out all the functions of life)

B) grow and develop ( due to an increase in size or an increase in the

number of cells)

C) respond to stimuli ( anything that causes a change or response);

usually this response results in movement

D) maintain homeostasis (regulation of an organism’s internal, life

maintaining conditions despite the changes that occur around them)-

making internal changes to maintain the right amounts of food and

water in the cells

E) Use energy- which either comes directly or indirectly from the

Sun

F) reproduce- make other living things like itself

G) Has a lifespan- time period in which organism is alive

Check for Understanding

So Now Let’s Think About This!

We just learned about the characteristics/ traits all living things

must share. So now let’s make a decision! Revisit your do now

answers and see if you want to make any changes!

1) Does each one you chose share these traits?

2) Are there any you left out that should be included?

Hint: There are 17 living things on the list!

Exit Slip- Match the trait to the real life example. Some traits are used

twice.

made of cells grow and develop uses energy has a life span

responds to stimuli reproduces maintains homeostasis

1. The child cried when receiving her shot.

2. Juan measured 54 inches on his 10th birthday.

3. Humans have a body temperature of 98.6°.

4. The marathon runner ate 2 bowls of pasta before the race.

5. The cat had 5 kittens in her first liter.

6. Monarch butterflies live between 2-6 weeks.

7. The infant gained 2 pounds in three weeks.

8. Dogs pant to cool themselves down.

9. The dog jumped up and barked when the door bell rang.

10. A human body contains about 30 trillion cells, some bacteria have

only one!

Enrichment: Similar Yet Different!

Even though all living things share certain traits ,there are many

difference among them. However, there are some organisms that are

very similar yet have distinct differences.

Choose two of the following pairs of organisms and make a chart

showing their similarities and differences.

Frog and Toad Dolphin and Porpoise

Butterfly and Moth Cheetah and

Bees and Wasps Sheep and Goat

Lizard and Salamander Crocodile and Alligator
