In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.

In this activity, learners build an electromagnet using a nail, a cork, a battery, and electrical wire. Use this activity to demonstrate how electric currents produce magnet fields.

In this technology activity, learners build an "alarming" doormat to keep siblings out of their rooms. Use this activity to teach learners about circuits, switches, and sensors.
