4th graders construct an ocean food web to learn about consumers and trophic levels, food webs, and food chains in this cool ecology science fair project.

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

Science fair project which simulates the global conveyor belts on a small scale, and observes the effects of wind, density and temperature on water movement.

Here's a fun activity that will have your child researching, collecting, and charting plant specimens from the neighborhood.

Your child grows a green thumb and flowers with this seed planting activity that also celebrates the 100th day of school!

In this open-ended activity, students will be given a small quantity of three types of materials and asked to design a prototype for “something that will improve the school.”

In this free science fair project, learn how to separate salt from water using heat. A great science project for elementary school kids.

This cool and easy elementary school science fair project idea provides the basic information on the use of our senses to experience the world about us.
