Will increasing the amount of salt in water effect how slow or fast the water freezes?

Plants need water to grow. In this project we learn how plants transport water from their roots to their leaves

Most people assume that cold water freezes more quickly, but could that be false? Does hot water freeze faster than cold water? Let's find out!

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

The objective of this science fair project is to investigate salt water density.

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?

In this enlightening transpiration experiment, kids will explore how the loss of water from plants through transpiration contributes to the water cycle.

Study the life cycle of the common blowfly as it relates to forensic investigation. Record the first time you see flies, maggots, and eggs.

This science fair project idea compares biodiversity between drops of water.

Using an empty tennis ball can and a swimming pool, you will determine if it's possible to have a conversation under water.

How does water pressure change with depth? Kids learn how pressure works underwater with this cool and easy demo.

Demonstrate the properties of pressure and surface tension to explain how water can stay inside an upside down glass using cardboard.

In this science project, learn about water transport in plants and make a beautiful dyed floral arrangement with cohesion, adhesion, and xylem tubes!

Science fair project which determines if plants really do need water to grow, or whether they just need to be kept wet.

Test whether plants can grow without sunlight and water.

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

Have your child kick off their summer vacation by making a miniature water slide!

Discover whether a metal will expand under hot water.

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

Discover whether cold or hot water from the faucet will boil faster on the stove.

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 free science fair project, learn how to separate salt from water using heat. A great science project for elementary school kids.

This science fair project explores how osmotic pressure forces water through the root up into the plant.

Have you ever noticed the way a dropped stone makes a fun pattern in a pond or lake? What's the science behind these splashy occurrences?

Did you even wonder why some rocks are round and smooth while others are broken up into small pieces?

This science fair project will help students learn about non-vascular plants, such as mosses.

Do you love to make Jell-O? Find out in this science fair project idea if it is possible to make Jell-O with just warm water.

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

What is surface tension? Kids will discover how water-skating insects use surface tension to keep from sinking by making a model water walker.

The project investigates how water and movement affects erosion.
