Water Motor
Source Institutions
In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

Build Your Own Hydroelectric Generator
Source Institutions
Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

Oil Spill Cleanup
This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

Aluminum-Air Battery: Foiled again!
Source Institutions
Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.

Tiny Geyser Models
Source Institutions
In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.

3-2-1 POP!
Source Institutions
In this physics activity, learners build their own rockets out of film canisters and construction paper.

Feel the Heat
Source Institutions
In this design challenge activity, learners design and build a solar hot water heater. Their goal is to create a heater that yields the highest temperature change.

Kosher Dill Current: Make Your Own Battery!
Source Institutions
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.

Push It Out
Source Institutions
In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

Pot-in-Pot Refrigeration
Source Institutions
In this activity (on page 2 of PDF), learners create a low-tech refrigerator that requires no electricity to keep food from spoiling.

Four of the States of Matter
Source Institutions
This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.
