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

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

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

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.
