Science Buddies: "Ask an Expert"

My third grade son selected turning Milk into Plastic for his Science Fair. I have found all kinds of information on how to do it. My question is how would I word the Problem/Question portion of the project? We want to keep it pretty simple. The only thing I've really came up with is "Can milk be turned into plastic?" It's been years since I've used the scientific method. Any suggestions would be appreciated as I am still the mom who knows everything in his eyes. Thank you

Hello. We noticed you posted the same question in the Physical Science Forum. It helps both our mentors and students if you only have one thread open so that our mentors can best help based on what has already been discussed. Based on your question, we feel the question is better suited to the Physical Science forum. Therefore, we are closing this thread.

Good luck, and thanks for using Science Buddies!
