Science Fair Project Idea
Plastics are made of polymers, chemical structures containing many repeated subunits. How does the polymer type of a plastic affect the biodegradability of the plastic? Do research on how plastic is made and what types of polymers are used for making different plastics. Can you learn to make your own plastic? What materials can you use for making plastic that is biodegradable? Test biodegradability by burying plastic samples for different lengths of time. (Kadar, 2004) Reducing solid waste… Read more

If you like to bake, this might be an interesting project for you. When you're following a recipe, do you ever wonder why certain ingredients keep showing up time after time (e.g., baking powder in quick breads)? Do you notice that certain ingredients tend to occur in a particular ratio to one another (e.g., amount of shortening and sugar, or amount of shortening and flour, or number of eggs and amount of flour)? What happens if you use more or less of an ingredient than the recipe calls… Read more

Some plastics undergo an unusual transition, from a hard, glassy state to a soft, rubbery state, with increased temperature. For this project, you should do background research on the effects of temperature on different types of plastics. Make sure that you understand the difference between thermosetting and thermoplastic polymers. You should also look for information on the glass transition temperature (Tg) for different plastics. Pure polyvinyl acetate has a Tg of 28 C (about… Read more

Safety Adult supervision required for experiments using boiling water.
Science Fair Project Idea
There are many types of construction materials used for wood-frame houses. Compare the different uses for and strengths of different building materials, e.g.: particle board, plywood, pine, oriented strand board (OSB), and drywall (gypsum board, SheetRock). The Science Buddies Materials Science Resource will be helpful for learning about different ways to measure material strength. You should be sure to use the same cross-sectional area of each material in order to make fair comparisons.… Read more

You can measure the viscosity of a fluid using a glass tube and a marble with slightly smaller diameter than the tube. Seal one end of the tube. Fill the tube with the fluid to be tested. Drop the marble into to the tube and measure the time it takes to fall a fixed distance. Repeat the measurement several times, and use the average value. How does viscosity change with the amount of sugar dissolved in water? How does viscosity change with temperature? Read more

Use a video camera to analyze the angle of lift with different clubs. Measure the distance the ball travels. Be sure to conduct a sufficient number of trials with each club so that your results are consistent. This can also be a great way to work on your swing! (Idea from Goodstein, 1999, 83-85.) Read more
