This science fair project investigates which of two learning modes most commonly used in school, visual and auditory, is better for information retention.

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.

Test for a correlation between perceived color and heart rate. Using a stethoscope and stop watch, measure the heart rate (beats per minute) of volunteers.

Create a colorful, informative display that illustrates the properties of blood cells. Prepare slides using samples of fresh raw beef or chicken bone marrow.

Measure the speed of the earth's rotation using protractors and meter sticks. This science fair project measures the angle of the sun in relation to earth.

The objective of this science project is to investigate why NASA has been using aerogel for the Stardust Project for collecting gas and dust from comets.

Create an organic plastic product using vinegar and cream. Track decomposition over course of several weeks. Compare decomposition with traditional plastics.

This project uses toy cars to determine how friction and gravity affect cars and braking.

This science fair project idea produces sounds by creating vibrations using different objects.

This project involves the development of a website using free software online to promote the value of science.

Sink or swim? Calculate the density of various fruits and vegetables using water and a kitchen scale.

Science fair project which examines how stopping a tomato's ripening process using the enzyme ethylene effects the tomato plant and its reproduction cycle.

How does frost form? How fast does it form? Do this simple science project using a plastic glass, rock salt and some water to learn about deposition.

In this fun guessing game, your child uses his sense of smell and taste to figure out what is in the container. Here's how to play:

Many ancient cultures used the rising or setting sun to create calendars. Observe the setting sun once a week to come up with your own solar calendar!

This experiment uses a voice recorder to monitor the progression of a message in the telephone game as it deviates from the original.

Show your child that the simplest ingredients (salt and water) can be used to illustrate the concept of density!

In this activity, your child will learn about a style of gardening that uses moss, also called "kokedama."

Amaze your kids by separating a salt and pepper mixture using an "electric spoon" charged with wool.

Learn how matter transmits sound with a simple, hands-on experiment using sand, water and air.

Here is a nifty science experiment using Epsom salts to make "frost" appear on a piece of glass.

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

Wild-type and GAPDH mutant Caenorhabditis elegans were used as an example of how glucose or sugar affects the lifespan of humans.

Design and build a scale model representing living tree architecture. Then build a full-size version using one or more lives trees, and test your creation.

In this windmill model science project, you will build a windmill to learn about wheel-and-axle machines and how these simple machines are used to do work.

Using simple materials found around your home, you can reinforce the static electricity concept by helping your child build a simple device with zapping power!

The goal of this science fair project is to demonstrate magnetic forces of attraction and repulsion using a magnet and everyday objects.

In this project, students will learn what and how foods are grown in rain forests and if there are sustainable methods that can be used.

This science project challenges students to learn about and classify weeds and discover new practical uses for weeds.
