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

Marshmallows are made of sugar, water, and air pockets. Since the marshmallow is flexible, will air pressure cause it to expand when heated in a microwave?

Soil and energy don't go together, right? That would be as bizarre as a pairing of peanut butter and marshmallows! Well, actually...

How does frost form? How fast does it form? Do this simple science project using a plastic glass, rock salt and some water to learn about deposition.

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.

Kids will make predictions about cricket behavior by conducting this fun and easy experiment which simulates different environments for crickets.

In this science fair project, students will create a model of a shoreline, observe erosion and examine how jetties prevent erosion.

This science fair project idea examines whether the colors of the spectrum respond differently in the thermal aspect when radiated by the sun.

Here is a fun middle school science project on factors affecting solubility. Learn how dissolved solids can "crash out" to form crystals when conditions change.

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

What is elasticity? Students will investigate how this concept applies to bouncing ball physics by testing the bounces of balls made out of different materials.
