Young scientists will investigate people's preferences for saltiness, and make some inferences about genetics and diet.

Science fair project that examines how winter storms form and the relationship between temperature, moisture and snow.

This science fair project idea examines how well individuals can remember a story they were told and how accurately they pass that story along.

Why do ants like sugar? Do ants like artificial sweeteners too? Kids find out with this great inquiry-based science fair project.

While your cells are much too small to see without a microscope, you can create the look of a cell in your very own home with just an egg and vinegar!

This science fair idea examines hydrogel superabsorbent polymer crystals. They can absorb 500 times their weight in water. Can they absorb other liquids too?

Stories change as you retell them. The objective of this science fair project is to demonstrate how information gets interpreted, distorted and changed.

Do you think heat can affect a plant's growth rate?

This science fair project idea explores the egg's thin membrane.

Examine whether distilled water, spring water, or regular tap water yield faster plant growth.

Science fair project that examines how yeast grows, and which conditions allow for optimal growth. What types of nutrients does yeast prefer?

This science fair project idea teaches how the gases and pollution in the air affect the earth's atmosphere temperature.

Does dough rise faster with unbleached or bleached flour? Investigate in this science fair project idea.

Help your second grader observe the phases of the moon, and then let the fun loose: he'll get to chart his observations with marshmallows!

This science fair project idea discovers if an artificial light source will yield the same plant health and growth rates as light from the sun.

In this experiment we will be determining whether birds prefer certain colors of seed.

Brine shrimp usually live in saltwater. Investigate how salt concentration (salinity) affects the rate at which brine shrimp eggs hatch.

This science project encourages students to investigate the Mozart Effect, the idea that classical music promotes learning.

Kids will build a turtle habitat in order to observe the climate preferences of this cold-blooded reptile.

This science fair project idea discovers whether there are some objects that do not fall at a constant rate.

Science fair project which determines whether the size or the thickness of a piece of paper has an effect on how many times it can be folded in half.

This science fair project idea demonstrates that plants give off water.

This science fair project idea demonstrates how air resistance contributes to denser objects falling faster than less dense objects.

In this project, you'll build a model of the earth, complete with all seven continents and four major oceans.

This science fair project idea measures out the sugar of various foods and find out whether people can correctly determine how much sugar is in common foods.
