In this electrochemistry activity, learners will explore two examples of electroplating.

In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

In this activity, learners explore how wind energy can be generated on both a large and small scale.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

Learners place their hands on different metals and use an ammeter to monitor the flow of electricity from one metal to another.

Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.

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.

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, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

Learners build a simple one-cell battery and use an ammeter to measure the flow of current.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

In this activity, learners build and test a compass. Learners work in pairs and pretend they are stuck in the wilderness at night.

In this activity about electricity, learners build and test a paper clip switch to turn on a light bulb.

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.

In this activity about electricity, learners identify parallel and series circuits. First, learners examine and label diagrams of complete circuits.

In this design challenge activity, learners invent a pinball-like game where a kick stick hits a ping pong ball into a target that buzzes.

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

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.
