i am having trouble creating a research question for chemistry, could anyone help me out, please?
This is my claim, 'Green polymers are better than synthetic polymers'. I am using polylactic acid (PLA) as my green polymer, and either Polyethylene (PE) or High-density polyethylene (HDPE) as my synthetic polymer. My teacher said I have to use at least three factors for the variables in my research question, for example, its reactivity, temperature resistance, chemical properties, strength, etc.
Thanks~~!!!
