Find out whether putting something on top of a plant will inhibit its growth.

Prove that the Earth is not flat. The objective of this science fair project is to measure the angle of the sun and calculate the circumference of the Earth.

This super fun science project, perfect for young children, combines crafts, dressing up as animals, outdoor play, and life science learning.

Children have a naturally inquisitive mind. Foster their curiosity with a walk through an autumn field or park to answer age-old “why” questions. As you walk with your child, you can encourage them to ask questions.

This science fair project idea explores whether cats can be trained in the same way that dogs can.

Glass is see-through, but usually you can still see that it is there. In this experiment, we use baby oil to make glass go completely invisible.

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.

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

This science fair project idea explores how enzyme inhibitors, active sites, non-competitive enzyme inhibitors, and substrates work.

Find out whether optical mice are useful on all surfaces or if there are drawbacks to this supposedly superior solution to the traditional roller-ball mouse.

Cinnamon is tasty, but does it have super powers as well? Find out if cinnamon can repel mosquitoes in this outdoorsy experiment.

Teach kids about a fun way they can remember this more efficiently- the power of mnemonics. Kids will be amazed.

This science fair project idea investigates if heat from direct sunlight is hotter than heat from reflected sunlight.

Magnets vary in strength. Have your young scientist figure out which kind of magnet is the strongest when you have him conduct this attractive experiment.

This project leads to an understanding that a whole may be built of smaller parts that fit and work together and provides an introduction to basic tools.

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

The purpose of this study is to determine if people can tell the difference between organic and conventional food from looking at, smelling and tasting it.

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 idea explores alcoholic fermentation at work by making your own soda.

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.

What chromosome combinations determine a fetus gender? Use probability to think about whether a sperm and ovum will create a male or female in this project.

Have you ever noticed the way a dropped stone makes a fun pattern in a pond or lake? What's the science behind these splashy occurrences?

Science fair project determines relationship between number and variety of insects and spiders by collecting and counting invertebrates in a ecosystem.

Wonder why bugs always fly around your lights at night? This experiment determines whether insects are attracted to the heat or the light.

This science fair project idea recreates the movement of planetary bodies in order to learn why they sometimes appear to move backwards.

With Halloween right around the corner, find a way to use your brain and reward your tummy with a new type of science -- candy science!

Science fair project which determines whether it is numerically possible to be connected to every person on the earth within six degrees of separation.

Science fair project that uses muriatic acid to develop fingerprints that would otherwise be invisible.

Discover which fabrics shrink the most in the wash and why.

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