I am teaching a class on rabbits and other small animals as well as assisting in a Drama Class. My son is attending a gardening class and a trip involving six countries. It's a good experience all round.
Anyways, when we got home the lad wanted to play with some of his toys but I kept falling asleep on him due to a short sleep night, so I suggested instead that we do an experiment. We are using Supercharged Science as our science at the moment and for a while I've been wanting to the hovercraft experiment.
Being the scientists that we are we switched it up a bit.
Aurora experiment called for paper cups, CD discs, juice lids, balloons and hot glue. We chose that the lad would use a CD disc and I would use a plastic protection ring. We wanted to know if there would be a difference in how they worked. The directions Aurora gave didn't work for us, due we think to the difference in juice lids. We found what worked best was popping open the lid.
