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 create an electrical circuit and investigate how some dissolved substances conduct electricity.

In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.

In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

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.

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

In this activity, learners explore how engineers incorporate biometric technologies into products as well as the challenges of engineers who must weigh privacy, security and other issues when designin

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

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

In this robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.
