Primary 1, 2 and 3 loved having Professor Science come to visit them to tell them all about the sun, moon and stars.  We had the chance to explore gravity by catching bubbles and using marbles and feathers to see which would fall to the floor fist.  We were very surprised to find out they fall at the same time after watching a slow motion video.  We even got to eat donuts after discovering that the universe is in the shape of one!
