This science fair project idea determines which method of hand cleansing is the most effective.

The objective of this science fair project is to study the photosynthesis process and demonstrate the important role that leaves play in the process.

Handedness and footedness refer to whether people prefer to use their left or right hand and foot. In this experiment, test hand and foot dominance.

Explore how sound waves are reflected and absorbed by producing echoes. Analyze which locations produce echoes.

Spiders don't go to grocery stores or fast food chains to get their food -- they set up traps and wait for their food to come to them!

Determine which material produces the strongest static charge.

Are red apples really sweeter than green apples? The objective of this science fair project is to test the theory with quantitative evidence.

Science fair project that determines whether wireless networks damage living plants. Are WiFi radiation hazardous to your health?

This cool science fair project teaches kids about temperature, density and buoyancy using balloons that float with normal air. No helium required!

Explore the wave-particle duality of light! Learn how light can behave as both a wave and a particle in this cool physics science fair project idea for kids.

This science fair project idea investigates the difference in reaction times between boys and girls.
