Part 1: Research and plan
Students can research what type of plastic that they want to make (from corn, potato, milk, etc).
They can use the Smarter Science framework and their steps to inquiry poster or booklets (http://smarterscience.youthscience.ca/posters-and-pdfs) to brainstorm what variable that they would like to change and what they would like to stay the same. They may choose to compare types of plastic (commercially available vs. potato plastic vs. plastic made with casein, etc.) or thickness or different types of preparation (plastic made from potato starch powder vs. from grated, real potato).
