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

The objective of this science fair project idea is to examine light refraction as it passes through liquid crystals.

Science fair project which teaches you how to make your own homemade glue by combing curdled milk with baking soda.

Demonstrate the properties of pressure and surface tension to explain how water can stay inside an upside down glass using cardboard.

This project determines what category of person is most likely to be ticklish.

Young physicists will wrestle with a discrepant event: the Hammer Ruler Trick. They'll make some inferences about torque, balance, and center of gravity.

Discover whether a metal will expand under hot water.

Find out whether matte or shiny nail polish lasts longer.

In this science fair project, we'll use a liquid crystal thermometer to find out whether exercising makes a difference in people's temperature.

Determine whether butterflies like to drink sugar water, salt water, or plain water.

This science fair project idea compares biodiversity between drops of water.

This science fair project idea examines the reason boats are shaped and engineered.

The objective this science fair project is to determine whether a bigger bag will allow a homemade hot air balloon to fly higher than smaller bag.

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

This science experiment tests if dog saliva can really help heal wounds.

This science project challenges students to study deer behavior in their natural habitat- the feeding patterns, social behaviors, male to female ratio, etc.

In this science fair project, you'll make a "ghost" appear in a test tube, and learn about what happens when hot water and cold water interact.

Will increasing the amount of salt in water effect how slow or fast the water freezes?

How does frost form? How fast does it form? Do this simple science project using a plastic glass, rock salt and some water to learn about deposition.

The objective of this science fair project is to examine the effects of temperature on salt and water solutions, as they form crystals over time.

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

Kids will learn how to measure the viscosity of liquids by making their own homemade viscometer in this great science fair project idea.

Here is a cool and easy science project to determine the rate of chlorophyll breaks down and how it affects the color change of grass from green to yellow.

In this science experiment, your child will test the strength of hollow structures in order to understand how strong bird bones really are.

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

This fun science project helps to investigate how much water can a plant take up and release in a certain period of time through the process of transpiration.

Science fair project that develops latent fingerprints on a non-porous objects by converting superglue from a solid state to a gaseous state.

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.

How good are humans at sound localization? Kids can try this cool science fair project idea to see how good their friends are at judging sound direction.

This science fair project idea teaches how the gases and pollution in the air affect the earth's atmosphere temperature.
