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.

Science fair project idea that examines different physical characteristics of a chosen animal. Make educated guesses about evolution based on animal's form.

In this free science fair project idea, we learn about surface tension and how it can support mass—in this case, a floating paper clip.

Why does purple cheese look nasty? Because color plays a big part in how we perceive the taste of different foods. Are birds just like us in this respect?

Kids will build a turtle habitat in order to observe the climate preferences of this cold-blooded reptile.

Wiggly worms are known for staying buried in the soil, but how does that affect plants? Are earthworms and plant growth related?

This science fair project teaches students the differences between fruits and vegetables.

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

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!

Can a horse lead itself to the carrot? Train your horse with carrots and boxes and test horse memory in this fun zoology science fair project.

Science fair project idea which teaches you how to make butter by separating cream into butter and buttermilk.

Stories change as you retell them. The objective of this science fair project is to demonstrate how information gets interpreted, distorted and changed.

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

Kids make a paperclip perform an act of magnetic levitation and test how effective various materials are at magnetic shielding in this science fair project.

This project compares the strength of one, two, and three-ply toilet paper.

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

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

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

Science fair project that examines the different types of precipitation, evaluates the density of snow and calculates the ratio of snow-to-liquid.

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

What is surface tension? Kids will discover how water-skating insects use surface tension to keep from sinking by making a model water walker.

In this project, you will observe and record changes in sunspots over two weeks.

In this plastic wrap science fair project, you'll learn about polymer permeability and find out which plastic wrap keeps food from dehydrating best.

Science fair project that determines whether cooling eggs helps them be peeled more easily. Compare the time it took to peel each egg.

This science fair project idea investigates the ability of different whitening toothpastes to whiten teeth.

Does skin thickness really decrease fruit spoilage? Find out in this science fair project idea!

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

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!

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

Kids will learn how to show the direction of magnetic field lines and create a permanent model using iron filings in this great science fair project idea.
