The chemistry about soapmaking is interesting. All it requires is oil and sodium hydroxide (lye). Get a good soapmaking book from amazon, and it will describe the chemistry behind soapmaking. You can even find a lot of information about soapmaking online. It depends on what the goal of your project is, but you can study the effects of using different types of oils (vegetable, crisco, lard), or you can study the effects of using different temperatures, or different stir times, or different amounts of lye vs. oil. I would only change one variable, make sure everything else is constant for the best results. Be meticulous in your observations and note taking. Plus, when you are done, you will have loads of soap to use! Good luck!

A lot of people send plastic items like milk containers for re-cycling or disposal. For people interested in re-using the plastic at home for crafts and hobbies, etc, you could look at whether there is any simple and cheap chemical process (perhaps a safe and cheap solvent) that can reduce the plastic items to a sludge, allowing it to be moulded into other items. You might look at adding plastic-hardeners to convert soft plastics into harder, more durable plastic.
