Test a Material with Physics and Chemistry Science Projects (32 results)

Test and observe the physical or chemical properties of materials. Whether you make your own material or use an existing one, test physical properties, such as appearance, texture, and brittleness, or chemical properties, such as how well a fiber dyes.

Slime Chemistry
Science Fair Project Idea
Scientific Method
Have you ever wondered how fun toys like Silly Putty®, Gak™, and Slime™ are made? These products are so much fun because of the properties of polymers, which make them delightfully bouncy, stretchy, sticky, moldable, breakable, hard, soft, and just plain fun! In this science project you can be the developer of your own slime product by changing the amount of a key ingredient. By observing the physical properties of your results, you can choose the best recipe for your new… Read more
Candy Snap
Science Fair Project Idea
Scientific Method
Have you ever broken a candy bar in half to share with someone? Some might snap in half quite cleanly, but others might be gooey and flexible. If you stick a candy bar in the freezer, will this change how the materials break? Try this sweet project to find out! Read more
Making Mixtures: How Do Colloids Size Up?
Science Fair Project Idea
Scientific Method
Have you ever wondered why some things disappear when they are put in water but other things do not? For example, you may have seen that salt disappears, or dissolves, when it is mixed in a glass of water. But when you throw a rock in a stream it will not usually dissolve, and instead it will just sink to the bottom. And then there are some things that do not act like the salt or the rock. These are called colloids. If you have made Oobleck out of cornstarch and water, then you have seen… Read more
Rusting Out: How Acids Affect the Rate of Corrosion
Science Fair Project Idea
Scientific Method
Have you ever left your bike outside in the rain? If so, you might have discovered unpleasant surprises afterwards—reddish-brown patches, known as rust, and your wheels, brakes, and gears might have stopped working so smoothly. In this chemistry science fair project, you'll learn why rust, a type of corrosion, is a serious problem. You'll also discover that not all rains are the same! Find out which ones can speed up the rusting process. Read more
The Viscosity of Motor Oil
Science Fair Project Idea
Scientific Method
The insides of a car engine get very hot when the engine is running. Motor oil lubricates the moving parts, to keep the engine operating smoothly. What happens to motor oil as the engine temperature goes up? Read more
From Dull to Dazzling: Using Pennies to Test How pH Affects Copper Corrosion
Science Fair Project Idea
Scientific Method
Pennies are bright and shiny when they are new, but become quite dull with time. What causes such a drastic change? Oxygen in the air combines with the copper in the penny to form copper oxide, which makes the penny look dull and dingy. You can make the pennies look like new again by soaking them in water that is corrosive enough to strip off the copper oxide layer. It turns out, however, that the same process that makes the pennies shiny has bad consequences when it comes to copper pipes: it… Read more
Magnetic Levitation: Experiments with 'Anti-magnets'
Science Fair Project Idea
Scientific Method
What happens if you hold a magnet next to water? You might think that water is not affected by magnetism, but in fact, the water is slightly repelled. Believe it or not, if the magnet is strong enough, you can use this effect to levitate objects that contain water, including insects and even small frogs! In this science project, you will learn about diamagnetism. Materials that are repelled by both poles of a magnet are called diamagnetic. The magnets you will use are not strong enough to float… Read more
Rubber Band Elasticity and Temperature
Science Fair Project Idea
Scientific Method
Many materials expand when heated and contract when cooled. What do you think will happen to the elasticity (stretchiness) of a rubber band when it is heated or cooled to various temperatures? Read more
Race Your Marbles to Discover a Liquid's Viscosity
Science Fair Project Idea
Scientific Method
How do you like your mashed potatoes? Thin and whipped smooth? Or thick and mashed into chunks? Your mouth checks out not just the taste of your food, but its viscosity, or how it flows on your tongue, every time you take a bite! In this science fair project, you'll learn what viscosity is, and how to measure it in common liquids around your home. Read more
How to Make the Boldest, Brightest Tie-Dye!
Science Fair Project Idea
Scientific Method
The clothes you wear are made of fibers that come from many different sources. Some fabrics are made from natural fibers, and some from manufactured or totally synthetic fibers. In this science fair project, you will explore how different fiber types react with dye. Are you dye-ing to find out which works best? Read more
