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, 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 extract DNA from their own cheek cells, then create a rudimentary DNA profile similar to those seen on crime scene dramas.

In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.

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

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

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

In this activity, learners use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

In this activity on page 5 of the PDF, learners use their knowledge of energy and batteries to create homemade flashlights.

In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

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.

In this activity, learners construct cars that are powered by hand-made, electric propellers.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.
