Discover that the absorbency of fabrics depend largely on the shape and structure of the individual fibers that make up the fabric.

The objective of this science fair project idea is to examine light refraction as it passes through liquid crystals.

In this science fair project, apply the principles of leverage and force by building six simple machines designed to set weights in motion.

Science fair project that examines what causes thunder and why a thunderclap sounds so loud. How is lightening related to the creation of sound waves?

Young physicists will wrestle with a discrepant event: the Hammer Ruler Trick. They'll make some inferences about torque, balance, and center of gravity.

Does putting soapy water on plants help or hinder plant growth? Kids learn about greywater and how it affects plant growth in this cool science fair project.

In this experiment you observe and determine how well your cat uses his whiskers to navigate through a maze.

This science fair project teaches students the differences between fruits and vegetables.

Design a survival kit. Brainstorm various survival scenarios. Address basic human requirements and natural resources. Describe each tool as well uses.

Kids will learn how to measure the viscosity of liquids by making their own homemade viscometer in this great science fair project idea.

Discover whether cold or hot water from the faucet will boil faster on the stove.

In this science experiment, observe convection currents forming and learn about how heat energy moves in liquids from hot to cooler areas through convection.

Kids will create their own version of Richard Feynman's rubber band heat engine to learn about thermodynamics with this cool science fair project idea.

This science fair project idea examines the reason boats are shaped and engineered.

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

In this Bernoulli's Principle experiment, you'll learn how an increase in the speed of a fluid, like air, decreases pressure.

Examine whether distilled water, spring water, or regular tap water yield faster plant growth.

Want to see a great example of Newton's first law? Kids will learn about basic physics with this fun, ballistic experiment.

This science fair project idea explores the egg's thin membrane.

Examine the effect of pressure on carbonation in soda.

This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.

Have your kid determine if a goldfish can be conditioned to expect food the same way Pavlov's dogs did with this fascinating science fair project.

In this project, all you need is a protractor to learn how to use the altitude of Polaris to find latitude on Earth. Polaris is also known as the North Star.

In this science experiment, your child will test the strength of hollow structures in order to understand how strong bird bones really are.

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

The objective of this science fair project is to study the photosynthesis process and demonstrate the important role that leaves play in the process.

The purpose of this science fair project is to build a basic radio.

This science project has students study a group of volunteer liars actively lying to study the behavior of a lie. Students see if they can figure out the truth.

The goal of this science fair project is to demonstrate different ways to generate static electricity and record its effects.

Kids will learn how to make a steam powered rocket boat, also called a putt putt boat or a pop pop boat, in this great science fair project for 4th graders.
