ElectroplatingAdd to list Details
In this electrochemistry activity, learners will explore two examples of electroplating.
Electric Paddle BoatAdd to list Details
In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.
Build an Electromagnet
In this activity, learners will build a simple electromagnet. They will test variables that would make the electromagnet stronger.
Conductivity MeterAdd to list Details
In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.
Water Wire: Electricity Flowing Through Water
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.
Smart Domino TricksAdd to list Details
In this activity, you take regular dominoes, and turn them into conductive switches that can turn on a LEGO RCX block or Pico Cricket (micro controller). LEGO RCX block or Pico Cricket is required.
In this design challenge activity, learners design and build a circuit: an "electric highway" that connects a battery and buzzer at least three feet apart using four types of materials.
Learners make a circuit board that has questions and answers. When the correct answer is chosen for a question, a circuit is completed and a light illuminates.
Flat FlashlightAdd to list Details
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.
Electric SwitchesAdd to list Details
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.
Musical Sculpting Machine: Squeeze Play-Doh to Make MusicAdd to list Details
Play-Doh is conductive! Use the semiconductive qualities of Play-Doh to make your own squeezable instrument. Pico Cricket is required.
Build a Bubble Circuit
In this engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.
Electric Messages: Then and NowAdd to list Details
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.
Flashlights and BatteriesAdd to list Details
In this activity, learners explore how a flashlight works, showing the electric circuit and switch functions of this everyday household item.
Stripped-down MotorAdd to list Details
