Did you know you can make paintings or drawings using sunlight? You can do it by leaving objects on top of special sun print paper until the light creates an imprint of the objects. How does this process work? How long should you leave the paper in the sun to get the best result? What does any of this have to do with the process of making the microchips that power our phones and computers? Try this project to find out! Check out this page for more science projects related to this process.  Read more

Some laundry detergents have added enzymes that break down proteins, helping to remove them from the cloth fibers, and thus remove stains. You can perform a scientific test of these enzymes' stain-fighting ability. Do background research on the enzyme(s) in the detergent, and on the substances you choose for making the stains. Try to predict for which substances the enzymes will be effective. Cut a piece of light-colored cotton cloth into identical 10 cm squares. Choose different… Read more

There are three different kinds of polymers used for kitchen plastic wrap: low density polyethylene (LDPE) (e.g., Handiwrap or Glad Wrap), polyvinyl chloride (PVC) (e.g., Reynolds PVC Foodservice Wrap or Boardwalk PVC Food Wrap Film) and polyvinylidene chloride (PVdC) (note: Saran Wrap used to be made with polyvinylidene chloride, but has switched to polyethylene. You will need to search for another brand that uses PVdC if you want to test it). Which of these materials is least permeable to… 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
