Materials


Use various tools to pick up food, ie.toothpicks, chopsticks, spoons etc.

Teach Lesson :


Predict which tool will work best for gathering food.

Do activity (Use various tools to pick up food) to see if hypothesis was correct.

Was child's prediction correct? Why or why not?

Make an analogy "How does this relate to birds?" Influences their survival. Impacts the environment.

Brainstorm examples in the real world where a body feature (adaptation) helps or hurts the survival of an animal. (Share with class)

Example: In canyon habitat... Snakes must eat mice or population of mice increases to the point of starvation for many mice competing for food.

Apply what you have learned to other animals.

How does this affect their environment?

Discuss lesson's relationship to universal concept (theme) and generalizations.

Discuss how the systems interact and are interdependent upon one another. Animals' beaks affect what food they can get. This increases or decreases others' populations. The attainment of food affects the environment.
