This science fair project idea demonstrates how air resistance contributes to denser objects falling faster than less dense objects.

In this cool science experiment, learn about magnetism and poles, and test magnet strength to find out if two magnets are twice as strong as one.

In this project combining nature, art, math, and science, children make rubbings of leaves then observe shapes and structures and sort the leaf images.

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 air pressure science experiment with a balloon and a jar, children will use heat to create a partial vacuum and suck a balloon into a jar.

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

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.

This is a quick, easy science fair project that conveys the idea of density to preschool and early elementary children.

Science fair project that demonstrates the effect of detergent pollution on fresh water birds' ability to stay afloat.

This science fair project idea determines if the size of the parachute will change the rate at which an object falls.

What animals are most popular? This project affords practice in data-collection, record-keeping and data-analysis through the investigation of this question.

Before you get ready for a delicious scramble or omelet, add a bit of science to your morning routine!

Why doesn't the ocean freeze? Students answer this question by simulating the chemical composition and temperature of arctic waters in their own home.

This science fair project idea investigates which objects float and sink in honey, water, and oil.

The goal of this evaporation experiment is to learn about how different external conditions affect drying time.

Milk is made of water and fat; but how can you separate the two? Find out in this color changing milk experiment.

Science fair project that examines condensation and the conditions needed in order for dew to form.

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

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.

This project determines whether Styrofoam, paper, or plastic cups are best for preventing ice from melting.

These science fair experiments demonstrate the chemistry of rust and the oxidation process.

Help your second grader observe the phases of the moon, and then let the fun loose: he'll get to chart his observations with marshmallows!

Kids will make a beautiful rainbow in a jar and learn what enables different types of liquids to remain distinct in separate layers.

In this science fair project, kids observe the expansion of liquids when frozen and determine if some liquids expand more than others in the freezing process.

In this fun science experiment, kids will determine the best method for ripening avocados and discover the cool chemical reaction that makes this possible.

Science fair project that examines the behavior of water and gravel in creek beds and the formation of sedimentary rocks.

This science experiment has students test whether a snail moves faster on concrete or dirt.

Science fair project which determines whether the size or the thickness of a piece of paper has an effect on how many times it can be folded in half.

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