Science Fair Project Idea
Strike a key on the piano, and you hear the string vibrating. Just about any object vibrates when it's knocked, but how much and how fast? What properties of the material affect the way it vibrates? This project helps you find out. You'll build a simple light-sensing circuit for measuring the frequency of vibrating springs. Read more

Ever try to tear a telephone book in half? Even though you can easily rip one or a few pages to shreds, the entire phone book has strength in numbers and holds together. This project is an introduction to measuring and comparing the strength of materials. Does spaghetti get extra strength if you bundle it together, or does strength simply increase proportionally with the number of strands? If you are interested in materials testing, get cracking!

Rockets are definitively an engineering challenge. These amazing gravity-defying machines have lifted test material, people, and even animals into space. Feel like building one yourself? In this science project, you will transform a water bottle into an aerodynamic bottle rocket with two compartments, one for the fuel and one for a payload. You will then test how well it performs when lifting mass vertically up into the air. Ready, set, soar! Read more
