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.

Science fair project about work and energy which uses a simple mathematical formula to predict how far a jar will roll down an incline.

Discover whether the â5-second ruleâ is effective at determining whether food is still safe to eat after being dropped on the ground.

In this science fair projects, students will grow out the bacteria that collect on air conditioner filters.

Determine whether butterflies like to drink sugar water, salt water, or plain water.

In this experiment, young ecologists will learn about a type of edge effect: how trees and plants at the edge of a forest can act as a weed filter.

In this fun science fair project idea learn about universal solvents and solutes and find out the solubility of several common liquid substances.
