In this online simulation, learners can see adaptation and camouflage in action. At the beginning, green and orange beetles are in green-leaved trees, and birds are more likely to eat the orange beetles. Learners can adjust the production of the nearby power plant turning the leaves more orange. Birds will continue to eat the beetles that are easier to see. This activity is based on the adaptation of the peppered moth during the Industrial Revolution in England. When learners set up a free account at Kinetic City, they can answer bonus questions at the end of the activity as a quick assessment.
