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
Which Materials Can Catch a Bubble?
Science Fair Project Idea
Scientific Method
Can you catch a bubble with your hands? What if you use another material, like a piece of paper or aluminum foil? Try this science project to find out which materials can catch a bubble without popping it. 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
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
Fishing Line Strength
Science Fair Project Idea
Scientific Method
If you like to fish and you'd rather not be telling the story of "the one that got away," then this is a project for you. What combination of properties makes for the best fishing line? Here are some suggestions for getting started on your background research into fishing line properties: knot strength, abrasion strength, shock strength, tensile strength, limpness, controlled stretch, and desired range of visibility (Dodson, 2006). Choose the properties that you think are most important, and… Read more
Get Crafty — Create Your Own Durable Paper Doll
Science Fair Project Idea
Scientific Method
Through the ages, creative minds have made an amazing variety of paper toys, many of them delicate, beautiful, and inspiring. All too often, though, they do not withstand very well the wear and tear of play. This science project is your chance to fix that. You will make paper dolls with movable parts and study how the choice of materials influence the strength of the toy. Beginning with a strong design, you will finish by making a durable paper doll (or toy) with moving parts. Read more
He Huffed, and He Puffed, But Didn't Blow the House Down! How Can Straw Make a Sturdy Building?
Science Fair Project Idea
Scientific Method
In the fairy tale of the three little pigs, the wolf huffed and puffed and blew down the first pig's straw house. But in reality, straw, tied into bales, is a viable building material that, when used properly, makes sturdy and energy-efficient buildings. Straw is a renewable resource that is available all over the world since it is the byproduct of growing grain. In this science fair project, you will test a straw bale covered with stucco to see if it's water resistant, and evaluate if it's… Read more
How Does Packaging Affect the Ripening of Fruit?
Science Fair Project Idea
Scientific Method
Why do different types of fruits come packaged in different ways? In this project, you will experiment with different ways of packaging fruit to see if it has an effect on the freshness of the fruit. Will a different kind of packaging allow the fruit to stay fresh longer? Read more
