PBS site offers an experiment kids can do at home to see how carbon dioxide can put out burning candles.

How can you carry 100 pounds of water easily? Is it possible? PBS site invites you to come along with Michael and Joel as they attempt to answer this question.

An experiment where several containers are set up with different numbers of seeds planted in each. The objective is to investigate how seed density affects the health of the plants that grow.

A simple experiment where pennies are thrown, then half are removed, to simulate how radioactive decay works.

Investigate the forces of electrons and protons in this experiment with electrostatic charges.

In this experiment, students construct models of larger red and smaller blue waves on index cards, and use them to investigate how light behaves when it is reflected off the front and the back of soap film.

Learn about how the intensity of light is governed by the inverse-square law with this activity. Activity has you experimenting to find that the intensity of light decreases as the inverse square of the distance.

Step-by-step instructions, with photos, of how to make a metal can come back when it is sent rolling away. The can uses both kinetic and potential energy to roll away and back.

A video and a short multiple-choice quiz on identifying possible outcomes and making predictions.

In this experiment, students observe what happens when a pan of soapy, colored water is heated. They will see that convection currents cause the fluid to rise and sink in a localized convection cell.

Can you defy the force of gravity by making liquid in a toy rise and fall without turning it over? This experiment will show you how to use hand boiler that uses temperature and pressure to move liquid into the top chamber.

How can you cut a rock without a saw? Is it possible? PBS site invites you to come along with Mike and Victor to find out.
