Scientific Method
Even though many cities have recycling programs, a lot of trash still ends up in the dump. Find out which materials will break down and which materials won't. Will the results of this experiment change which products you often buy? Read more

Scientific Method
Have your parents ever found you munching on candy and asked you, "How much candy did you eat?" Instead of saying, "I do not know?" and getting in trouble, maybe you would rather say, "I ate precisely 10.7 cubic centimeters of candy, Mom." Make your parents proud of their candy-eating genius child (you) with this simple science project. 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
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

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
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

Scientific Method
What is your favorite color and why? Do you think that simple tasks might be biased by your preferences? Find out in this science project if your color preferences will bias your fine motor skills when doing quick, repetitive tasks. Read more

Scientific Method
Baby Beluga may swim in the deep blue sea, but the song does not mention how cold it is out there! Find out in this science project how a bit of blubber can be a useful adaptation when the water is ice cold. Brrrr! Read more

Scientific Method
Did you know that sunlight can actually be separated into the colors of the rainbow? And the light of different colors can be added together to make white light or new colors. This is an area of study where art and science overlap. In this science fair project, you will explore this area by drawing or painting "pie slices" onto a white circle and then combining them to make a new color by spinning the wheel using an electric drill.

Scientific Method
Some people have a photographic memory and can memorize anything they see almost instantly! Wouldn't that make homework easy? Other people can remember almost anything they hear. Try this experiment to see which type of memory you have. Read more
