Which Is the Better Insulation Material?
Science Fair Project Idea
Scientific Method
You've probably noticed that the price of gasoline has been going up and up lately. Heating oil will probably cost more this winter than last winter, too. Using good insulation material is one way to conserve energy and save money. What insulation materials work better than others? Read more
Use a Calorimeter to Measure the Heat Capacity of Water
Science Fair Project Idea
Scientific Method
Along with its many other interesting properties, water has the ability to absorb a lot of heat energy, while only experiencing a relatively small change in temperature. One way this property affects us directly is that our bodies don't change temperature rapidly on hot or cold days, since we are made up of mostly water. In this chemistry-with-an-electronics-flair science fair project, you will determine how the temperature of a small volume of water changes as you add precise amounts of heat… Read more
Study Chirality with a Homemade Polarimeter
Science Fair Project Idea
Scientific Method
Some molecules can be either left- or right-"handed." The left- and right-handed molecules have the same number and type of atoms, and their chemical structures look identical, but they are actually mirror images of each other. Many naturally occurring molecules have this property, called chirality. Chiral molecules can interact with polarized light in an interesting way—they rotate the plane of polarization. This chemistry science fair project describes how to make a homemade polarimeter… Read more
Does Chemical Lightening Affect the Structure of Human Hair?
Science Fair Project Idea
Scientific Method
Does your hair go crazy when the weather turns damp? Did you know that strands of hair can relax and lengthen when the humidity increases and then contract again when the humidity decreases? In fact, hair strands can be used as the basis for a hygrometer, a device which measures the humidity level in the air. Can a human hair hygrometer also detect changes in hair structure caused by chemical lightening? This project shows you how to find out. Read more
Make a Hygrometer with Strands of Hair
Science Fair Project Idea
Scientific Method
Does your hair go crazy when the weather turns damp? Did you know that strands of hair can relax and lengthen when the humidity increases and then contract again when the humidity decreases? In fact, hair strands can be used as the basis for a hygrometer, a device which measures the humidity level in the air. Will a hygrometer help you to predict bad hair days(!) or can you use it to help predict the weather? Read more
Can Cell Phones Survive a Drop Test?
Science Fair Project Idea
Engineering Design Process
Why do so many people use cell phone cases? Do cell phones really need the extra protection, or is it just because cases look fancy? In this engineering science project, you will test the durability of calculators instead of cell phones, find out if cases increase the durability of the device, and build some of your own cases that do!

Veggie Snap! Modifying Bending Stresses in a Flexible Rod
Science Fair Project Idea
Scientific Method
Have you ever broken a fishing rod? Or seen a treetop bend over and touch the ground (or even snap off) during an ice storm? These are examples of the effect of bending stresses on flexible rods. There are scientists who actually study this phenomenon and discover ways to prevent breakage, which leads to stronger fishing rods, building materials, car parts, and more. In this science project, you'll explore the bending stresses in flexible rods by testing asparagus stalks. Read more
Less Cowbell! The Unconstrained Truth About Constrained-Layer Damping
Science Fair Project Idea
Scientific Method
Noise is everywhere. From the clanking of a cowbell to the din of the lunchroom, we are surrounded by noise. Sometimes there's no way to get away from it, but there is a way to deal with it—constrained-layer damping. By simply creating a layered sandwich of somewhat flexible materials, what was once a noisy cowbell can become a "noise blanket." This science fair project shows you how to transform a noisy piece of metal into a sound-muffling constrained-layer damper. You'll record the… Read more
Experiment with Making Gels
Science Fair Project Idea
Scientific Method
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 many more. In this project, find out how gels are made and how they can be adjusted from firm to soft by changing the ingredients. Read more
Which Metal Is the Most Resistant to Corrosion?
Science Fair Project Idea
Scientific Method
Here's a practical engineering challenge: you need to build an enclosure for your dogs, using material that they can't chew through. It's going to be a lot of work to build, so you want to do it right. What material should you choose for the fencing? This project uses the scientific method to evaluate materials. Read more
