In this activity, learners explore how a flashlight works, showing the electric circuit and switch functions of this everyday household item.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

Visitors observe three beakers. One beaker contains an egg immersed in vinegar. Visitors observe carbon dioxide gas escaping from the shell as the calcium carbonate reacts with the vinegar.

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

In this cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

This is a web activity about simple machines. Learners will explore a lawn mower and identify six different simple machines which work together to help make our lives easier.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this physics activity, learners construct a small-scale version of a classic carnival game.

Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.

In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.

In this activity, learners discover how solar energy can be used to heat water.

In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.

In this activity (on the left side of page 5, continued on the right side of page 4 of the PDF), learners make models of colorful butterflies.

In this activity, learners create a toy that demonstrates the First Law of Thermodynamics or the Law of Conservation of Energy.

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

In this online game, learners build complicated machines to complete simple tasks. The game starts with a power source on one side of the screen and the task on the other side.

This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.

In this activity, learners build simple alarms that they can attach to anything, such as a drawer or doorway. This activity introduces learners to electricity, circuits, and currents.
