The school science fair is always a must for Bayley. We got there a little late, and then Hayden tried to escape at the end, so it wasn't the best...but I do hope he enjoyed it. He liked looking at the experiments the 6th graders put together, and he LOVED the OMSI presentation...probably because there were explosions involved.
It was a great science overview, even if they had trouble seeing from the chairs. They had a parent light a hydrogen filled balloon...and then one with hydrogen and copper so it would be a different color, to show the kids the difference between a physical change and a chemical change.
