Exploring Nanotechnology: Fold, Roll, & Stack Your Way to Super-Strong Materials
Science Fair Project Idea
Scientific Method
Advertisements for high-tech sports gear or the latest and greatest outdoor material promise lighter and stronger products every season. Is it a scam? How can engineers keep creating materials that are both lighter and stronger than anything known so far? The answer is in the nanoscale! Using nanotechnology, scientists can play around with the detailed structure of matter, leading to a whole new range of materials, some with amazing qualities. In this science project, you will get a glimpse… Read more

Have you ever seen an arch structure in a building, such as over a doorway or surrounding large windows? Arches have been used in structural engineering since ancient times. In this activity you will test the strength of a naturally occurring arch shape: the shell of an egg. So grab some eggs and put them to good engineering use in trying to answer the following question: Just how much mass can an eggshell can support? 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
Pounding Papyrus: How Ancient Egyptians Made the World's First Paper
Science Fair Project Idea
Scientific Method
It's hard to imagine a world without paper. You wouldn't have things like books, cards, comics, newspaper, construction paper, notebooks, cereal boxes, or that nice sound of shredding wrapping paper on your birthday. There was a time, though, when the only thing people had to write on were slabs of soft, squishy clay. When these slabs dried in the sun, they preserved simple ideas, but they were heavy, like carrying around a load of rocks. Not exactly easy to put in your pocket and carry around.… Read more

Have you ever helped your parents cook a pot of spaghetti? Strands of spaghetti are pretty long, so sometimes people break them in half so they fit into the pot more easily. How exactly does the spaghetti break? And what does this have to do with science? It turns out engineers and materials scientists study how materials break when they are bent. While professional engineers might be more concerned with steel beams in a bridge, you can still do a fun experiment with some pasta in your kitchen. Read more

Balloons are fun and come in a variety of sizes, colors, and forms that makes them well suited for decorations, water play, modeling, and other creative activities. But balloons also have uses outside of recreation; weather balloons, balloons used to widen obstructed arteries, and balloons that provide transportation are just a few examples. The first balloons were made of animal bladders or intestines. This made way for the latex, rubber, and nylon fabric balloons we see today. Have you ever… 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
