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.

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

This engaging project encourages young children to practice and refine the important scientific skills of sorting and classification.

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

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

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

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

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

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

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

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

This science project teaches young students about germs, bacteria, and the importance of washing their hands. Students will test what is the best way to wash.

What do worms eat? Kids find out what kinds of rotting leaves and vegetables worms prefer in this cool compost science fair project.

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

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.

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