thumbnail Do you love to make music, but do not have access to all the instruments you would love to play? Check out this fun science fair project about the physics of musical sound production. You will make musical instruments with drinking straws, one for each note on a one-octave major scale. Can you figure out the right lengths for a series of straw "oboes" in order to play a musical scale? Read more

thumbnail How far would you have to travel so that the light of the full sun would provide "daylight" no brighter than twilight on Earth? This project describes a method to verify the inverse square law: how light, sound, electrical signals, and gravity each decrease with distance from their source. When you have finished your experiment, you can use your results to calculate an answer. Read more

Science Fair Project Idea
thumbnail You know how to make new colors by mixing paint or crayons. For example, you get green by mixing yellow and blue, or orange by mixing red and yellow. With paint, blue, yellow, and red are primary colors, which you can use to make other colors. Have you ever tried making colors with light? Are the primary colors the same ones you use for paint? Do this experiment and find out. Read more

Science Fair Project Idea
thumbnail We encounter an amazing array of colors every day, from the greens of plants and the many colors of their flowers, to the pinkish blue of a sunset, to the artificial coloring in beverages. How do we perceive all of these colors? When light hits an object, some of that light is absorbed by the object, and the light that is not absorbed is what we see. In this science project, you will build a simple spectrophotometer from a cell phone and use it to investigate how visible light is absorbed by… Read more

Science Fair Project Idea
thumbnail Do you realize that you are constantly bombarded by particles? You do not feel them, you cannot see, hear, or smell them, but they are always there! These particles — collectively called background radiation — might even travel through you without ever interacting with the molecules in your body. In this science project, you will build your own cloud chamber to prove the existence of background radiation. You will then use your cloud chamber to determine if the background… Read more

thumbnail Ok, well you will not be making real monkeys fly, so what is this science project all about? You might think that flying, screaming monkeys and science project do not belong in the same sentence, but you will be working with toy monkeys, and toys can sometimes be great tools for exploring science. In this science project, you will launch flying, screaming toy monkeys and determine how far they fly with the stretch of a rubber band. The distance they will go can be graphed to see how distance… Read more
