This biodiversity project examines the biodiversity in your own backyard.

In this physics project, learn about the relationship between light intensity and distance using a laser pointer, flashlight, and graph paper!

Learn how to make a food pyramid with animals in a a coniferous forest ecosystem around your home.

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

Science fair project examining barometric pressure, and how it can be used to predict the weather. How does atmospheric pressures relate to weather conditions?

In this experiment we will be determining whether birds prefer certain colors of seed.

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

This science fair project idea investigates if webbed feet help a duck (and others) swim.

What do ants eat? Kids find out by observing a colony of ants in this cool zoology science fair project for 4th grade.

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

In this science fair project, students examine under what conditions individual plants release seeds and how far the seeds are released.

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!

Science fair project that examines how winter storms form and the relationship between temperature, moisture and snow.

This science fair project idea determines if crystals will absorb food dye and if colors will mix by the process of diffusion.

In this experiment, kids will see if pruning tomato plants makes them more fruitful and learn about the factors that contribute to a plant's fruit production.

In this simple circular motion experiment, you'll observe tangential velocity and learn about how acceleration and centripetal force affect an object.

Do you think heat can affect a plant's growth rate?

How do icicles form and what do they look like? Do this free science fair project and watch the formation of icicles occur right before your eyes.

Why does honey crystallize? This science fair project project answers this question and identifies the variable that makes this sweet solute crystallize faster.

Discover flight initiation distance as you play around in the park with this fun bird watching project!

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

What is persistence of vision? With this hands-on science fair project idea, students will demonstrate this cool and dramatic phenomenon in their own classroom.

Did you know your body is full of simple machines? This project looks at one of the third-class levers in the human body: your arm!
