Experiment with buoyancy to learn how a submarine rises and sinks in this classic science experiment.

This science fair project investigates why the number of visible stars changes from place to place.

In this cool experiment, learn how to find specific gravity of minerals using liquids of different densities to see which substances and items sink and float.

Science fair project that helps you better understand density by comparing the relative densities of cans of Coke and Diet Coke.

Science fair project that examines how to grow bacteria in a controlled setting, using simple materials from around the home.

This science project encourages students to investigate the Mozart Effect, the idea that classical music promotes learning.

Can you increase the light and plant growth in your garden using mirrors? In this experiment, measure light reflection and find out!

Kids will create their own version of Richard Feynman's rubber band heat engine to learn about thermodynamics with this cool science fair project idea.

Construct and experiment with a periscope using reflected light rays to gather an image.

Wind is an important source of renewable, green energy. The purpose of this science fair project is to build and operate a windmill generator.

Would your dog prefer homemade or store-bought food? Raw or cooked? Test your dog's preferred diet in this fun experiment.

Using an empty tennis ball can and a swimming pool, you will determine if it's possible to have a conversation under water.

What is mulch? Kids will provide soil with a wet blanket of mulch and see if that helps keep drought-stricken soil damp.

This science fair project teaches kids experimental design and how to test if subjects can really sense if they are being watched.

This science fair project idea explores whether a sundial is as accurate as an atomic clock when telling time.

Science fair project that compares the ecology of different soil samples by identifying which sample has the most invertebrates living in it.

What are the benefits of good posture? Kids will learn about the cognitive effects of good posture through conducting and observing a controlled experiment.

This science project lets students explore the number of spots on a ladybird and how to treat ladybugs with respect.

This cool and easy elementary school science fair project idea provides the basic information on the use of our senses to experience the world about us.

Study the life cycle of the common blowfly as it relates to forensic investigation. Record the first time you see flies, maggots, and eggs.

This science fair project idea studies which kind of rock (sedimentary, igneous, or metamorphic) is most damaged by frozen water.

This science fair project idea explores how far the âdanger zoneâ is from different types of caution signs.

Demonstrate how static electricity can cause an object to move. It also examines just how an object affected by static electricity will move.

In this popcorn experiment, students can explore how two things made out of the same material can have very different appearances and densities.

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

This science fair project idea attempts to train a worm to complete a simple maze in order to find out if worms can learn and remember.

This science fair project idea measures the growth of bread dough and finds out how long it takes for the dough to stop rising.

Tree rings can tell the age of the tree but also information about the world. This science experiment uses tree stumps to discover new facts.

This science fair project compares the allelopathic affects of juglone, a chemical agent produced by the Black Walnut tree, on two plants.

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