In this cooking and food science fair project, measure how the water content of dried beans changes with time. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by...

In this cooking and food science fair project, determine if you really need 6 quarts of water to cook a pound of pasta. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction,...

In this energy and power science fair project, the student will calculate the heat energy produced by an active compost pile, surrounding a tin can filled with water. The Science Buddies project ideas are set up consistently beginning...

A number of electrical, nuclear, solar, and wind science projects and energy activities are described on this page, with links to each activity.

In this human behavior science fair project, the student will learn about Piaget's developmental stages and the Theory of Conservation. The student will investigate the age at which children understand the equality of numbers and mass....

By comparing the feet of different water birds you can discover how they propel the birds through the water. This Science Buddies project show you how to modify swim fins to simulate ducks' feet, greebes' feet, and the feet of...

By using Alka-Seltzer and different temperatures of water, you can determine the effect of the water temperature on the chemical reaction of the tablet. The Science Buddies project ideas are set up consistently beginning with an...

Amaze your friends and family by moving water with just a few turns of your wrist, this is known as an Archimedes screw. In this science project, you will build a very simple Archimedes screw, to transfer water from a low-lying location...

Every criminal leaves behind evidence at the crime scene. The trick to catching the criminal is collecting all of the evidence and making sense of it. This is what the forensic expert does. In this science project you will be correlating...

Of course it can, you say: ice is water and ice floats. And you're right. But we're talking about water in the liquid phase Can liquid water float on water? The goal of this project is to investigate what happens to layers of water with...

Can water remain liquid below its normal freezing point? If it does, that water is supercool(-ed). This project shows you a method for supercooling water. You can test water from different sources to see whether or not it can be...

Have you ever wondered what makes water 'bead' up on a freshly waxed car? In this project you'll investigate the chemistry of surface tension by measuring how many drops of water a penny can hold.

If you look carefully, you could find dozens of similar interesting phenomena that are all linked to the surface tension of water. Here is a project that will help you understand and measure the properties of water surface tension.

Did you know that when you dip your finger in water and pull it out, the water is actually pulling back on you? Here's a way you can measure how much.

To survive, we need oxygen in the air we breathe. Oxygen is also essential for most aquatic organisms, but there is much less oxygen available in water than in air. Learn how to measure dissolved oxygen and then see how oxygen...

When it comes to making ice cream, in order to make the mixture cold enough to freeze, you surround the container with ice and rock salt. This experiment helps you learn how the addition of salt (or other substances) affects the freezing...

Here is an interesting project that could be approached from several different scientific angles: Environmental Science, Weather & Atmosphere, Chemistry, or Plant Biology. You can probably think of your own variations to emphasize...

Have you ever wondered how a ship made of steel can float? In this project you'll investigate how much weight boat hulls of various shapes and sizes can support without sinking.

We know that plants, and even bouquets of cut flowers need water to survive, but we often do not think about how water moves within a plant. In this science project, you will use colored water and carnations to discover how water travels...

Whether a chick can breathe inside its shell is an interesting question. Every animal needs oxygen to survive, so the chick must get air somehow. Try this science project to discover if the pores in a chicken egg shell allow water to...

Clean water is not a given everywhere in the world. In this science fair project, students will investigate whether sunlight could be used to disinfect contaminated water. The Science Buddies project ideas are set up consistently...

You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar...

Chances are, you have several materials around your house made of gelatinized materials. Gels are used in all kinds of products and materials: pudding, diapers, insoles, packaging, ice cream, toothpaste, and much more. In this project,...

What makes some objects more streamlined than others? Find out which ordinary objects around your house are made to move smoothly through the water in this easy experiment. Which objects will produce the most drag when pulled through the...
