Build Your Own Wind Turbine
Source Institutions
Learners construct an electricity-generating wind turbine out of a plastic bottle.
Working with Wind Energy
Source Institutions
In this activity, learners explore how wind energy can be generated on both a large and small scale.
Electric Paddle Boat
Source Institutions
In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.
Creepy Crawlers
Source Institutions
Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.
The Electric Squeeze
Source Institutions
In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.
Going for a Spin: Making a Model Steam Turbine
Source Institutions
In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.
Eddy Currents
Source Institutions
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.
Bottle Cars
Source Institutions
In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.
Motor Effect
Source Institutions
In this activity about electricity and magnetism, learners examine what happens when a magnet exerts a force on a current-carrying wire.
Geothermal Power Plant Model
Source Institutions
In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.
Motor Bird
Source Institutions
In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.
Speedboat
Source Institutions
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.
Personal Fan
Source Institutions
Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.
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.
As the Rotor Turns: Wind Power and You
Source Institutions
In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from
Cable Car
Source Institutions
In this activity, learners string a line across the room and build cable cars that can move from on end to the other.
Build Your Own Hydroelectric Generator
Source Institutions
Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.
Weather Vane and Anemometer
Source Institutions
In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.
Keep Out!
Source Institutions
