Science Fair Project Idea
Scientific Method
Have you ever heard about different blood types? Do you know what your blood type is? Antibodies help scientists determine different human blood types. This project is a practical introduction to the human immune system in which you will learn about what antibodies are, how they are formed, and how they can be used to identify different types of cells.

Scientific Method
Test your multitasking skills with the Timed Up and Go (TUG) Test! In this challenge, you'll evaluate a person’s functional mobility when they're focused versus when they're distracted. Can your brain handle walking and talking at the same time? Let’s find out! Read more

Scientific Method
Do you care about the look and feel of your skin? Then you probably know that your skin prefers to be well hydrated (moisturized). Dry skin often cracks, gets inflamed easily, and looks dull. If you go to the store, you will find many skin care products that promise to hydrate your skin. Among them are cosmetic face masks (sometimes called facial masks) that you put on your face to provide the skin with water and nutrients. In this science project, you will make your own hydrogel face masks… Read more

Scientific Method
One of America's favorite snacks is potato chips. Although potato chips are very tasty, some varieties are not very healthy for you. A typical 1-ounce (oz.) serving of a well-known national potato chip brand contains 150 calories, 90 of which are from fat. How greasy are your favorite potato chips? Try this science fair project, and you'll get a visual understanding about how much oil a potato chip can hold. Read more

Scientific Method
Do you like solving mysteries? In this experiment, you can find out how a DNA fingerprint can help you figure out whodunit. The answer might just be in the "sequence" of events! Read more

Scientific Method
In this science experiment, you will model and test how visualization of a task can change the accuracy of your fine motor skill performance. You will use the small muscles in your hands to model how your body would perform on Earth versus a space launch. Read more

Scientific Method
How do scientists "copy" DNA? They use a process called the Polymerase Chain Reaction, or PCR. The key to making this process work is having a short piece of DNA, called a primer, that will stick to the larger piece of DNA you want to copy, called a template. In this science project, you will test how the number of matches and mismatches in a primer will affect its ability to stick, or anneal, to the DNA template during PCR. Read more

Scientific Method
Ever used a pair of molecular scissors? Restriction enzymes are molecular scissors that cut DNA into pieces. Find out which enzymes will cut, and where by making a restriction map. Then you can figure out what will happen if you change the sequence of the DNA. Will the same enzymes still cut the new DNA sequence? Read more

Scientific Method
Did you know that our brains are split into two parts, right inside our head? One half is the left brain and the other half is the right brain. Some people use one half of the brain more than the other half when they are doing certain activities, like talking or reading. The half that is used is sometimes tied to which hand they prefer to use. If someone likes to use their right hand when doing an activity, like drawing or throwing a ball, do they also prefer to use their right ear, eye, or… Read more

Scientific Method
"Use it or lose it!" Sure, we all know physical exercise is important to keeping our bodies fit. But how important is physical exercise to your brain? In other words, is there any connection between an active body and increased brain power? This is an easy project where you can test the effect of exercise on a critical brain function: memory.
