Any time is the perfect time to whip up a delicious batch of fluffy pumpkin cookies.

This science fair project idea explores whether factors such as temperature and concentration affect the pH of a solution.

Your child can turn cookie dough into a big pile of colorful painted fall leaves ready for eating!

In this science fair project, we learn how air molecules move as a result of density, convection, and air currents.

Science fair project which simulates the global conveyor belts on a small scale, and observes the effects of wind, density and temperature on water movement.

Learn how to make a hygrometer to measure relative humidity in this project. Make a sling psychrometer hygrometer with gauze, thermometers, and a bottle.
