This science fair project idea investigates which objects float and sink in honey, water, and oil.

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.

This science fair project idea produces varying pitches of sound.

Believe it or not, the common spud has enough electrochemical energy to power a small digital clock.

How do series and parallel circuits work, and which produces the brightest light in a light bulb? Construct both in this project and find out!

Students pit the heat capacity of water against the heat capacity of oil while looking at the effects of dipole rotation in this cool science fair project idea.
