G-man had to complete a science project for his class by the end of the quarter. We didn't have it done in time for the science fair. It turns our 2nd graders aren't the best communicators. G only gave me a weeks notice for that one. But now we are learning the questions that need to be asked to try and overcome those communication barriers. Plus I have no room to talk. I think I'm the queen of poor communication skills.
G-man chose to blow up balloons with carbon dioxide by mixing vinegar and baking soda. We were trying to see if we could create enough gas to make one burst. We were able to get one to fly off the soda bottle. But not to burst. I was tired of using up all my vinegar.
It was the perfect 2nd grade science project. G-man really loves chemistry and blowing things up.
