of the concepts. It does not matter that your experiment has been done a thousand times before or that your teacher already knows the results. What matters is that you don ’t know the results and that you can work independently to find a verifiable answer. Should I work in a group or by myself? The decision about working individually or in a group should be given careful consideration.
