This science fair project examines how seeds hitchhike on animals and clothing.

In this science fair project, we'll use a liquid crystal thermometer to find out whether exercising makes a difference in people's temperature.

Soil and energy don't go together, right? That would be as bizarre as a pairing of peanut butter and marshmallows! Well, actually...

Is it amplitude? Weight? Length of string? Kids will discover what factors changing the period of a pendulum depends on in this fun and easy physics experiment.

What is a compound microscope? Kids find out by making one of their own in this cool science fair project.

In this science project, young children observe, record, and create collections of colors in their world and increase their powers of observation.

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.

In this science fair project you will make a model of a cell membrane using very simple material.

Which music genres have the fastest tempos? The slowest? This experiment determines if there's a relationship between beats per minute in a song and its genre.

This science fair project idea explores if the length of the string that an object is suspended on has an effect on how fast or slow it swings.

Explore if planting seeds in a certain direction will affect how fast it germinates.

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.

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

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

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

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 experiment explores whether reading text on a computer screen or type on paper leads to better retention of the information read.

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?

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