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.

How do organic materials become soil? This science experiment measures what materials biodegrade.

Ever wondered how a plant drinks water? This science project will teach you how and help you create a beautiful floral display!

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

Word color association is just a fancy way to talk about the way we connect colors with words.

Plants and light seem to be good buddies, but how far does the friendship really go?

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

There are many benefits to bugs and insects. This science project shows how cockroaches, termites, and other critters benefit our planet.

Test whether plants can grow without sunlight and water.

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

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?

The goal of this evaporation experiment is to learn about how different external conditions affect drying time.

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

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

These science fair experiments demonstrate the chemistry of rust and the oxidation process.

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.

Do plants get crowded? Have your curious kid investigate how plants respond if they're forced to grow together in a confined space.

This science fair project idea creates cool new colorful fabric pattern designs and experiments with the mixing of colors.

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

When you cut a flower to put into a vase, it'll eventually wilt, even with water and sunshine. But is there another scientific secret to keeping flowers fresh?

This simple project makes young children aware of their sense of smell and its capacity for providing them with information about their world.

Wiggly worms are known for staying buried in the soil, but how does that affect plants? Are earthworms and plant growth related?

This science fair project idea investigates whether air has mass and weight.

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

What's the science behind those out-of-sight roots? Find out if you can trick roots into growing in different directions.

In this experiment, your child will create two compost bins and see if he can determine what attracts fruit flies.

This science experiment tests whether warm or cold water works best in making cut flowers last longer.

This project leads to an understanding that a whole may be built of smaller parts that fit and work together and provides an introduction to basic tools.
