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!

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.

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

In this experiment you observe and determine how well your cat uses his whiskers to navigate through a maze.

Explore the craters, maria, and highlands on the surface of the Moon! In this fun science project you'll create a 3-D model of the moon using paper mache.

Kids will learn how to make a steam powered rocket boat, also called a putt putt boat or a pop pop boat, in this great science fair project for 4th graders.

In this science fair project, learn how a mineral streak is made and how it can help identify an unknown mineral.

Science fair project that compares the freezing temperature of salt water and freshwater in order to learn about supercooling and condensation nuclei.

This science project has students study a group of volunteer liars actively lying to study the behavior of a lie. Students see if they can figure out the truth.

Is it amplitude? Weight? Length of string? Kids will discover what factors changing the period of a pendulum depends on in this fun and easy physics experiment.

Kids will learn about the interaction of lactose and lactase in milk and discover why we describe enzymes as catalysts in this fun science fair project.

This science fair project idea examines which type of insulation holds in the most heat.

Have your kid determine if a goldfish can be conditioned to expect food the same way Pavlov's dogs did with this fascinating science fair project.

This science fair project focuses on the use of the enzyme amylase found in human saliva to break down starch into sugar.

This science fair idea examines hydrogel superabsorbent polymer crystals. They can absorb 500 times their weight in water. Can they absorb other liquids too?

Test whether plants can grow without sunlight and water.

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!

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

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

Does your middle school teenager have good reflexes? Gauge his reaction time in this science and math activity that requires only a yardstick and a friend.

The objective of this science fair project is to test the growth rate of a plan in a crystal medium in comparison to traditional soil.

This science fair project idea explores how the shape of a boat affects its density and how much weight it can float.

This science fair project will help students learn about non-vascular plants, such as mosses.
