In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

Break open that used musical toy and squish some Play-Doh over the circuit boards, and you will hear some weird and distorted sounds the manufacturer never intended!

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.
