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.

Look for a correlation between temperature and the intensity of cricket chirping. Measure ambient temperature and sound intensity in decibels.

Help your kindergarten scientist predict and observe as she explores the science of smell...and have a great time doing it, too.

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

What colors can dogs see? Do they only have black and white vision, or can they see other colors too? Find out in this cool science experiment!

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?

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

Let your kid experiment with textures among fabric and other materials that are smooth, rough, soft, or slippery—and then they'll make a texture book!

In this science fair project, students will use four different household objects to see which ones form the most or best crystals.

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.

Make an edible play dough with your child to help her develop her sensory and motor skills.

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.

In this science fair project, kids measure how weather conditions affect how fast a puddle evaporates.

In this experiment, you experiment with laser jet toner, a magnetic fluid, as it moves, bubbles, and forms unique shapes.

This science fair project looks one of the most important factors affecting seed germination: water. A fun and easy plant biology experiment for 3rd graders.

This science fair project idea investigates if fats add to the flavor of food.

How do crystals form? In this science fair project, students will use three different saturated solutions to see how different minerals form crystals over time.
