This project uses science and art to help students learn and teach others about Earth's endangered and extinct species.

Ant behavior is closely related to light intensity. This free science fair project idea examines how fast ants dig when they are exposed to to light and dark.

Science fair project which measures the shadow cast by a meter stick at various times in order to predict the circumference of the earth.

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 science fair project idea investigates how optical distances change the apparent size of an object as seen through a magnifying lens.

Science fair project in which you will start a fire from scratch without using matches or a lighter.

What is biodiversity? Kids will study different areas of their backyards to see which is the most diverse to learn about biodiversity and random sampling.

Science fair project that compares the ecology of different soil samples by identifying which sample has the most invertebrates living in it.

The objective of this science fair project is to experiment with balancing everyday objects and observing the the effects of gravity on materials.

In this science fair projects, students will grow out the bacteria that collect on air conditioner filters.

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

This project investigates the affect of storage temperature on microwave popcorn.

Science fair project which examines the relationship between frequency of spider web vibration and spider's response time.

This science fair project idea examines how well individuals can remember a story they were told and how accurately they pass that story along.

This science fair project idea measures the growth of bread dough and finds out how long it takes for the dough to stop rising.

Science fair project that examines how yeast grows, and which conditions allow for optimal growth. What types of nutrients does yeast prefer?

Science fair project that examines albedo, and how this information is applied in the design of cars, sportswear, and other items. Which colors reflect light?

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 project teaches students about organic farming and the benefits and disadvantages of commercial plant food.

This project examines whether playing music during class helps students learn or if it distracts students from learning.

How do organic materials become soil? This science experiment measures what materials biodegrade.

This science fair project idea explores whether people have an innate feel for the passing of time from a few seconds to 20 minutes.

This science research project challenges students to think of more effective lobster farming methods.

This science fair project focuses on a polymer called hydrogel super absorbent crystal which absorbs water, swelling to many times its original size.

What can you do with hair after its cut? This science project teaches you practical uses for human hair.

Watch pre-packaged seeds and seeds taken from inside fruits and vegetables grow. Which ones will grow faster? Read more in this science fair project idea.

This science fair project idea determines the probability of a coin landing heads or tails.

Science fair project that determines whether mass and weight are the same or different.

Science fair project which determines whether people are more likely to follow rules if they are easy to understand.

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