Can you better explain the unbalanced forces again with respect to moving objects? I know they can be balanced (even though my misconception logic says otherwise) but I am still not sure I understand HOW or WHY.
I also made an observation: At least via the video coverage available, both the cameraperson and the teachers have spent more time (except in the 6th workshop classroom) with the all-boy groups, as well as allowing more boys to speak during the class discussions. As a psychologist I actually do not find this surprising, just continually interesting, given the research in this area. I wonder of anyone else noticed this?
