Circuit Game
Source Institutions
In this activity, learners build a game that tests their steadiness. Learners construct the game board by setting up an electrical circuit and a wand.
Working with Wind Energy
Source Institutions
In this activity, learners explore how wind energy can be generated on both a large and small scale.
Plugged in to CO2
Source Institutions
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.
Electric Paddle Boat
Source Institutions
In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.
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.
Gel Electrophoresis
Source Institutions
In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.
Build a Battery
Source Institutions
Learners make a simple battery out of "sandwiches" of aluminum foil, pennies, and a salt water-soaked paper towel.
Electric Switches
Source Institutions
In this activity, learners incorporate a simple switch into a battery/bulb circuit. Learners will use their knowledge of circuits to design and make their own switches using common materials.
Electric Messages: Then and Now
Source Institutions
In this activity, learners explore electronic communication, the Morse Code system, and advances all the way through text messaging. Learners build a simple circuit, send messages to one another.
Bottle Cars
Source Institutions
In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.
Control the Flow
Source Institutions
In this activity about electricity, learners build and test a paper clip switch to turn on a light bulb.
Dough Creatures
Source Institutions
In this technology activity, learners light up the room with electrifying play dough creations. Learners use conductive and insulating homemade play dough to build simple circuits.
Dance Pad Mania
Source Institutions
Make your own "Dance Dance Revolution" dance pad! In this design challenge activity, learners work in teams to build a dance pad that lets you use your feet to sound a buzzer or flash a light.
History of Electricity
Source Institutions
This is a series of demonstrations about different electrical and magnetic phenomena.
High Tech Fashion
Source Institutions
In this technology activity, learners build simple circuits, design soft circuits using conductive thread, and then sew switch-activated circuits.
How Do We Convert Mechanical Energy into Electrical Energy?
Source Institutions
In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.
Using Ohm's Law to Build a Voltage Divider
Source Institutions
In this activity, learners apply Ohm’s Law to construct voltage divider circuits. Learners discover how to read resistor codes and calculate resistor values.
Yogurt Cup Speakers
Source Institutions
Learners build a simple electromagnet, then use this electromagnet to transform a yogurt container into a working speaker. They can connect their speaker to a radio and listen as it transmits sound.
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.
