In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

In this classic activity, learners investigate natural selection by becoming birds foraging for food on an island.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity, learners build one or more edible coral polyps and place them together to form a colony.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this outdoor activity, learners use a "litter-critter" wheel to help them identify different animals they find living in a natural litter habitat.

In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.
