In this electrochemistry activity, learners will explore two examples of electroplating.
In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.
In this activity, learners will build a simple electromagnet. They will test variables that would make the electromagnet stronger.
In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.
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.
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.
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.
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.
Play-Doh is conductive! Use the semiconductive qualities of Play-Doh to make your own squeezable instrument. Pico Cricket is required.
In this engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.
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.
In this activity, learners explore how a flashlight works, showing the electric circuit and switch functions of this everyday household item.
In this activity, you'll make an electric motor--a simple version of the electric motors found in toys, tools, and appliances everywhere.
In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.
In this activity, learners discover how a piece of fruit can act as an electrolyte, conducting electricity between two different metals.
In this activity, high voltage is applied across a pickle to emit a yellow glow. This activity should only be conducted by skilled adults and is best suited as a demonstration.
In this activity about electricity, learners explore what happens when you blow a fuse.
