In this cool science experiment, learn about magnetism and poles, and test magnet strength to find out if two magnets are twice as strong as one.

This project compares the strength of one, two, and three-ply toilet paper.

Is it solid or liquid? Create oobleck and witness the amazingly weird oscillation between the two!

In this experiment, your child will create two compost bins and see if he can determine what attracts fruit flies.

Milk is made of water and fat; but how can you separate the two? Find out in this color changing milk experiment.

In this popcorn experiment, students can explore how two things made out of the same material can have very different appearances and densities.

This classic children's game-connecting two cups with a string-demonstrates sound's ability to travel through air vs through a solid.

In this fun science fair project, make two different scale models of our solar system using Astronomical Units and planets' relative size!

In this Halloween-themed activity, young learners will find out what happens when they mix two household items together to create a surprising chemical reaction.

Observe how your brain works while it is focused on one thing, and how it works while you are distracted by another thing.

The objective of this science fair project idea is to determine if sound travels best through the air, water or a solid.

This science fair project idea investigates how a bottom keel helps keep a boat from rocking back and forth.

It's rhyme time! With this science fair project idea, your child will find out which words can be considered easy rhyming words, and why.

This science fair project idea investigates how optical distances change the apparent size of an object as seen through a magnifying lens.

Learn whether Mylar Balloons last longer than Latex Balloons or vice versa.

This fun experiment provides a concrete and visually striking illustration of photosynthesis.

Learn about this simple machine and make a pulley of your own to use for fun science trials.

Kids will make a beautiful rainbow in a jar and learn what enables different types of liquids to remain distinct in separate layers.

Demonstrate how static electricity can cause an object to move. It also examines just how an object affected by static electricity will move.

Kids will learn some cool stuff about chemical reactions by determining what happens when you mix different concentrations of hydrogen peroxide and yeast.

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

The objective of this science fair project is to analyze the effects of salinity and temperature on water.

Have you ever seen fruit decay? Find out if a fruit will rot faster if you open it versus leaving it untouched!

Why doesn't the ocean freeze? Students answer this question by simulating the chemical composition and temperature of arctic waters in their own home.

The goal of this project is to create an exciting topographical map out of dough.

Observe corn seed germination to learn about dicots and monocots and how plants grow from seeds to seedlings to full-grown plants!

Observe with your third grader what happens when food starts to decompose, and boost science skills simultaneously with this experiment!

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

This science fair project idea investigates whether plants can survive being frozen.
