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 hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity, learners collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.
