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

This science fair project idea explores which is better for diffusion and cell absorbing, more surface area, or more volume.

In this cool project, create a lighted, scale model of the different layers of the Sun, including the core, radiation and convection zones, and photosphere.

Become familiar with ratios and learn how to measure the diameter of the Sun and the Moon in this fun science fair project idea.

Determine whether the relationship between a personâs armspan and height are genetic.

In this project students learn about the golden ratio and investigate if it can be used to predict people's assessment of beauty in others.

Check out this game that provides an enjoyable way of demonstrating how recorded results can be expressed in whole numbers, fractions, and decimals.
