Learners take on the role of environmental engineers as they design water filters.

Have you noticed the plastic rings that are used to hold six-packs of soda? Those rings are great for carrying cans, but they're real trouble when they become trash that animals can get tangled in.

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.

In this activity, learners are invited to imagine the park of their dreams!

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.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
