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 activity related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube.

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

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

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

Learners use compasses to detect the magnetic field created by current moving through a wire. This is one of four activities learners can complete related to PhysicsQuest 2008.

In this activity, learners apply Ohm’s Law to construct voltage divider circuits. Learners discover how to read resistor codes and calculate resistor values.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

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.

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

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.

Learners use the current flowing in a wire to create a magnetic field that turns a magnet. Learners can use this property of electromagnetism to build a magnet-powered pinwheel.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

In this activity and demonstration about electricity and magnetism, learners observe how the current generated when one copper coil swings through a magnetic field starts a second coil swinging.

This lesson focuses on graphene and its electrical properties and applications.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this activity, learners explore electricity and conductivity to find that many things conduct electricity including copper, pencil lead, fruit, play-doh, and even people!
