This project concerns activity happening millions of miles away, on the sun.

Science fair project which measures the amount of heat energy released by a burning candle by calculating how many calories of heat it emits.

Have your child observe, measure and record the amount of space objects occupy, and you'll have an inside space explorer on your hands in no time!

Introduce your fourth or fifth grader to volume by having him build rectangular prisms, and then count each sugar cube to check his volume calculations.

This hands-on activity gives your child an opportunity to apply various strategies to solve a problem and to check if his answer makes sense.

In this cool experiment, learn about the forces of resistance in a liquid and race marbles in a cylinder to find out which fluids have a high viscosity.

This fun science project helps to investigate how much water can a plant take up and release in a certain period of time through the process of transpiration.

Learn about calorimetry, make a bomb calorimeter, and experiment with combusting different nuts to see which one produces the most energy!

The objective of this science experiment is to evaluate the affects of high and low heat capacity on a material's heat retention ability.

The objective of this experiment is to evaluate the effects of acid rain on plants.
