Experimental Question: How does environment affect the survival of these organisms?
Procedure:
1. Write a hypothesis for each environment:
a. Desert Sand:
If preys are of color close to desert sand, they can more easily escape their predators
b. Mountain Rock:
If preys have a color close to mountain rock, they can more easily escape their predators.
c. Grassland:
If preys have colors close to desert sand or rock mountain, they cannot camouflage in the
grassland and will be easily spotted by their predators.
2. Run the simulation 3 times for each environment (desert, mountain, and grassland) and record
your data.
3. Calculate and record averages for your data.
4. Complete the analysis and discussion questions.
