Our Scientist of the week taught us about the breathing balloon! He mixed sodium bicarbonate (baking soda!) with vinegar and the balloon started to “breathe” and inflate! He explained why, but then the crew wanted to try the experiment again with adding water to the vinegar to see what would happen when the baking soda was added. The next balloon got BIGGER! Finally, they wanted to see what would happen when they added baking soda to water, they were not so impressed with the results, but they did a lot of thinking! Below are the pictures!! They had a blast learning together and asking lots of questions!!
