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.

In this science fair project, young children discover what happens when two fluids that have different densities get together.

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.

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

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 project combining nature, art, math, and science, children make rubbings of leaves then observe shapes and structures and sort the leaf images.
