Electroscope
Source Institutions
In this activity, learners make an electroscope out of a foam cup, straw, aluminum pie pan, thread, and foil. Learners use their electroscopes to test for static electricity.

Forward-Reverse Switch
Source Institutions
In this activity, learners build a switch to turn electrical circuits on and off.

Insulators and Conductors
Source Institutions
In this activity, learners explore the concept of conducting or insulating electricity.

Stretch the Chain and See the Light
Source Institutions
In this activity, learners use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb.

Kosher Dill Current: Make Your Own Battery!
Source Institutions
This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

Motorized Balancing Toy
Source Institutions
In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.

Circles of Magnetism IV
Source Institutions
In this activity related to magnetism and electricity, learners observe as two parallel, current-carrying wires exert forces on each other.

Bright Lights
Source Institutions
In this activity about electricity, learners imagine that they are out in the wilderness and it is getting dark. Their task is to use the materials supplied to build a simple flashlight.

Shake It Up!
Source Institutions
Learners drop a magnet through a coil of wire to create electric current in a circuit. LEDs in the circuit allow learners to detect the direction of current flow.

Circles of Magnetism I
Source Institutions
In this activity related to magnetism and electricity, learners create a magnetic field that's stronger than the Earth's magnetic field.

Magnetic Suction
Source Institutions
In this activity about electricity and magnetism, learners discover how a doorbell works. A coil of wire with current flowing through it forms an electromagnet that acts similar to a bar magnet.

Hand Battery
Source Institutions
In this activity about chemistry and electricity, learners form a battery by placing their hands onto plates of different metals.

Electromagnet
Source Institutions
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.

Weather Vane and Anemometer
Source Institutions
In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

Light Bulb Challenge
Source Institutions
In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.

Keep Out!
Source Institutions
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.

Motorized Car
Source Institutions
In this design challenge activity, learners build a car that uses a battery-operated motor to "drive" at least ten feet.

Jitterbugs
Source Institutions
In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.

Minibot
Source Institutions
In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.
