Magnet Mania
University of KansasAdd to list DetailsIn this activity, learners explore the relationship between electric charges and magnetic fields. Learners create a magnetic field using electricity and observe its effect on the magnetic needle of...
How Do We Convert Mechanical Energy into Electrical Energy?
PBSAdd to list DetailsIn this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo. Learners observe what happens to the compass needle when the magnet...
Motorized Car
WGBHAdd to list DetailsIn this design challenge activity, learners build a car that uses a battery-operated motor to "drive" at least ten feet. Educators can use this activity as a fun, hands-on way to...
Piezoelectric One-Way Remote
The ExploratoriumAdd to list DetailsIn this activity, learners construct a device out of a piezoelectric igniter, like those used as barbecue lighters. Learners use the device to remotely start current flowing in a simple series...
Invisible Investigations
University of KansasAdd to list DetailsUsing indirect observational methods, learners distinguish between charged and uncharged objects. This lesson uses magnetic marbles to represent charged particles and iron filings to represent a...
Kick Stick Challenge
WGBHAdd to list DetailsIn this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong...
Building a Basic Series Circuit
Perkins School for the BlindAdd to list DetailsThis activity was designed for blind learners, but all types of learners can use it to build and examine a basic electrical circuit. Other activities using the circuit set-up are outlined, such as...
Personal Fan
Community Science Workshop NetworkAdd to list DetailsCool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor. This activity introduces learners to circuits and switches as well as conduction and...
Motor Bird
Community Science Workshop NetworkAdd to list DetailsIn this activity, learners build a bird that flies in place with help from a motor, wire, and some straws. This engineering activity introduces learners to circuits and motors, automata, and...
Minibot
Community Science Workshop NetworkAdd to list DetailsIn this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors. Note: a drill and drill bit are...
