Make a Speaker
Source Institutions
In this activity, learners explore how an electromagnet works by making a simple one. Using this knowledge, learners design a diagram to make a working speaker using household materials.
Community Wind Project
Source Institutions
In this thought-provoking activity, learners plan a hypothetical project to build and operate wind turbines in their community.
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.
Static Water
Source Institutions
In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.
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.
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.
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.
Happy City
Source Institutions
Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.
Two Button Buzzer Circuit
Source Institutions
In this activity, learners explore an everyday situation, where either of two or more buttons can ring a buzzer.
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.
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.
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.
Circuits with Friends
Source Institutions
In this activity, learners explore the parts of a circuit by modeling, as a group, a “human” circuit.
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.
Water Wire: Electricity Flowing Through Water
Source Institutions
In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.
Flat Flashlight
Source Institutions
In this activity, learners build a tiny but powerful flashlight out of simple materials. Use this activity to introduce learners to electrical circuits and conductivity.
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.
