Let's Get it Popping......Or Not


       Last class we collaborated in groups conducting experiments with balloons. Dr. Smirnova demonstrated brushing on 'magic' blue water on top of a balloon, then poking the balloon with a needle and it not popping. It was up to the class to figure it out how and why!!!!
        This activity was really a lot of fun. My group conducted a total of 5 experiments. We tried to look at every aspect of how, what and why. We were given 5 balloons, a pin, and a beaker filled with 'magic' blue water with a wire brush inside of it.

       This activity was a way of Dr. Smirnova showing us as students what our students would be doing. She didn't give us any hints, just gave us the tools to solve the problem ourselves.
 

We had to form a hypothesis before we even got started. In the end, our hypothesis was proved to be wrong, and we discovered the liquid had nothing to do with it at all!!! It was the area of the balloon--either the top center or the bottom center of the balloon wouldn't make the balloon pop if that is where the pin is pushed in!!!!
                                                                  

          I am definitely excited to conduct experiments in my own classroom oneday!!

  1. When we conducted this experiment my group didnt feel the need to use all 5 balloons. I really like that you took into consideration, WHY were we given this many balloons and there must have been a purpose behind it. Seems your group really took the stance of being "students" and what you think your students would do in your classroom and i really like that. BTW i love your layout with all the balloons, it made me want to read your blog and i was intrigued by it.
