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 outdoor activity, learners discover how the environment around a building affects the growth of plants.

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

Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.

This is a tape and glue activity in which learners make binoculars that they can decorate and then use to go bird watching.

In this activity, learners observe fly behavior and then build a flytrap.
