This science fair project idea teaches that time always passes at the same rate and nothing we do in our daily life âreallyâ affects how fast it moves.

Check out this fun science fair project idea for 1st grade: a solar eclipse model that demonstrates total, partial, and annular solar eclipses.

This project explores whether plants can live and grow when "watered" with juice, soda, or milk.

This project is a vivid, concrete introduction to the basic but important idea that plants need sunlight and water to grow.

Water, along with soil and light, is a necessary component for plant growth. So what's better for promoting plant growth: tap water, or rain water?

This science project challenges students to study deer behavior in their natural habitat- the feeding patterns, social behaviors, male to female ratio, etc.

The objective of this science project is to determine the length of time for different seeds to germinate.

This science fair project idea explores how length affects the weight a bridge can hold.

This science fair project idea investigates if webbed feet help a duck (and others) swim.

In this project children practice the scientific method while playing with puffy paint.

This project examines whether people's taste perception is influenced by what they see.

This experiment challenges students to forecast the weather based on the surrounding areas' weather.

In this project, create and examine garden mulch to find out what critters live in the messy, muddy layers just above the soil.

This science fair project idea investigates how the shape of an object affects drag.

In this science fair project, young children will become aware of and have the opportunity to experience the four basic tastes: sweet, sour, salty, and bitter.

Cinnamon is tasty, but does it have super powers as well? Find out if cinnamon can repel mosquitoes in this outdoorsy experiment.

This science fair project idea determines if the size of the parachute will change the rate at which an object falls.

In this science fair project, kids observe the expansion of liquids when frozen and determine if some liquids expand more than others in the freezing process.

This science experiment tests why guacamole goes brown and if leaving the pit in will stop guacamole from turning brown.

In this experiment, students will create their own version of coquina, a sedimentary rock thatâs formed by seashells and sand, cemented by seawater minerals.

This science experiment examines the role of fat in food, especially in making bread rise and whipping cream.

Science fair project idea that examines different physical characteristics of a chosen animal. Make educated guesses about evolution based on animal's form.

Why does purple cheese look nasty? Because color plays a big part in how we perceive the taste of different foods. Are birds just like us in this respect?

In this science fair project, we'll explore how blocking the sun's light can stop those can stop photosensitive paper from changing color.

Kids will learn how to clean fish tank the natural way. Add catfish to the tank and see if your water gets cleaner.

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

This science fair project idea determines which method of hand cleansing is the most effective.

The objective of this science project was to build a model of a volcano and observe reaction between different substances, including baking soda and vinegar.

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

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.
