Simulate evolution with some colorful "critters" and carnivorous "beaky birds." Simulations are helpful to demonstrate processes like evolution that take place over many years. Observe how adaptations such as camouflage help organisms survive and pass on traits to offspring. Recognize evolution happening simultaneously in both the predator and prey (bird and critter) populations.

Common rocky intertidal species include kelp and seagrasses, crabs, snails, mussels, sea anemone, sponges, fish, barnacles, sea urchins, sea stars, and visitors such as gulls and other seabirds. These organisms have evolved unique adaptations to allow them to survive, including mechanisms to prevent drying out, camouflage, hard shells or exoskeletons, adherence to rocks, mechanisms to reflect sunlight, or the ability to trap water. In this design challenge, participants create a creature that lives in the rocky intertidal shore.
