Science fair project which measures whether tsunamis are more destructive when they are caused by an earthquake or by a meteor.

Make a backbone model to explore human anatomy and life science.

In this fun project, use a memory game to test various age groups and determine whether aging directly affects short-term memory loss.

Kids will discover the meat science behind the meat they eat, and find out how to use safe chemistry to make meat more tender.

Saturn is the ringed planet in our solar system, a gas giant with rings made of ice and dust. Let's make a cool scale model with an old CD and some glitter!

In this project, build an insect model that shows how the head, thorax, and abdomen fit together! Learn insect anatomy by constructing a paper mache critter.

Do different types of oil mix or stack? Find out in this science fair project idea!

Examine which metal conducts more heat by boiling water in 3 pans made of aluminum, copper, and stainless steel.

Are you ready to be a detective for science? Then get out your magnifying glass and start studying fingerprints!

Learn about sound physics and do a survey experiment to explore the difference between sound and noise in this science project.
