What do you do when it gets very cold in winter? You probably turn your heater on, put on an extra layer of clothes, or cuddle under a warm blanket. But have you ever thought about why a jacket helps you stay warm? What is the purpose of our clothes, and why are they made from fabrics and not foils? Find out the answers in this activity; your results may even tell you the best way to stay warm in the cold! Read more

The Height Limits and Linearity of Bouncy Balls

Science Fair Project Idea

Scientific Method

You might think that plants and animals have little in common with batteries, springs, or slingshots, but they actually do have something in common. Both living and non-living things store and transfer energy from one form to another. In this physics science fair project, you'll investigate this energy storage and transfer, not in a plant or animal, but in bouncy balls. You'll find out if there are limits on how much energy can be stored and if there are losses when the energy is transferred. Read more

How Does Color Affect Heating by Absorption of Light?

Science Fair Project Idea

Scientific Method

Why is it more comfortable to wear light-colored clothes on a hot summer day? Why wear a dark-colored jacket for early-morning fishing on a cold lake? How much difference can it make? Here's a project where you can quantify how much difference color makes for absorbing heat. Read more

Kaleidoscope Science

Science Fair Project Idea

Scientific Method

A kaleidoscope is a fun toy that creates amazing images when you look into it. Wouldn't it be fun to create those images yourself? Check out this project to learn how to build your own kaleidoscope and to learn how the inside of a kaleidoscope works. Then you can create and adjust your own amazing, colorful images! Read more

Do you remember your last parade, party, or fair? You might have been surrounded by sounds of all kinds: fireworks, music, and, maybe even the famous (or infamous) sound of kazoos. A kazoo is a very simple musical instrument, made up of a hollow pipe with a hole in it. They may be simple, but these little noisemakers are a great way to explore sound. In this activity you'll be investigating how kazoos work by building your own! Read more

Did you know that the modern guitar is an instrument that dates back over 4,000 years? The first guitar music was published in 1546, during a time when guitars still had strings made from animal intestines! While guitars have a long history, they are still extremely popular in modern day music. Have you ever wondered how they make the music you listen to everyday? In this activity we're going to make our own guitars, and experiment with the different sounds we can create. Read more

Measuring Sugar Content of a Liquid with a Laser Pointer

Science Fair Project Idea

Scientific Method

Did you know that you can figure out how much sugar is in a liquid without ever tasting it? In this science fair project, you will learn how to measure the concentration of sugar dissolved in a liquid by using a laser pointer, a hollow prism, and some physics. You will discover how refraction, or the bending of light, is the key to measuring the sugar content of a liquid with a laser pointer. Read more

Build a Levitating Water Fountain with the Stroboscopic Effect

Science Fair Project Idea

Engineering Design Process

Can you make water fall up? Or make drops of water hover in mid-air? While you might not be able to make water defy gravity, you can create the illusion that it does using something called the stroboscopic effect. In this project you will make use of the stroboscopic effect to build your own "levitating water" fountain. Read more
