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

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

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.

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

The objective of this science fair project is to observe the differences in heat absorption for darker colors vs. lighter colors.

Demonstrate the properties of pressure and surface tension to explain how water can stay inside an upside down glass using cardboard.

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 project, you'll build a model of the earth, complete with all seven continents and four major oceans.

How powerful is the reaction between baking soda and vinegar? Find out here!

In this science fair project, students learn how pressure can make the minerals in a rock line up in the same direction and form bands and foliation.

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

How does smell affect taste? Ready your taste buds--in this project, you'll gather some test subjects and do a taste test to see how much smell affects taste.

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 determines which method of hand cleansing is the most effective.

What is topography? Kids find out by learning to make and read a topographic map in this awesome science fair project idea.
