And now a word about Structures and Functions

Structures  Fins  Arms  Stems  Roots  Tongues  Shoulders  Get the picture?

Functions: What the Structures Do to help the life form SURVIVE  Lift leaves up  Catch food  Protection  Camouflage  Hear prey  Run fast

When writing examples of Adaptations:  1) STRUCTURE: Adjective – describe it AND name it  2) FUNCTION: What it does AND how it helps it SURVIVE.

Now Let’s Practice  For each of the following critters please write down the following:  3 structures  The functions of these structures TO HELP THE CRITTER SURVIVE in the wild.

Activity  In your notebook  Fashion a critter from your imagination  Include at least 5 structures  Be prepared to tell the class the function of those structures – how they help it survive

Make sure you explain your thinking!  Bad – teeth to eat prey.  Better - sharp teeth to tear into the skin of its prey.  You need to use ADJECTIVES with your structures and explain how the structures actually help the critter.

On a sheet of paper next to your critter:  1) What is the name and scientific name?  2) What does it eat?  3) What eats it?  4) What are the 5 structures you modeled?  5) What are the functions of the structures and how do they help it survive?  6) Describe its habitat – where it lives.
