QUESTION 1
What is the function of a plant’s roots?
To anchor the plant and absorb water and nutrients.
QUESTION 2
How do gills help a fish survive?
They let the fish take in oxygen from the water to breathe.
QUESTION 3
How does camouflage help an animal?
It helps the animal blend in and hide from predators.

Elaborate: design a survivor.

Have students design an imaginary organism with structures suited to survive in a specific habitat, and explain each part’s job. A printable structures sheet is in the Science library.
