Imagine trying to figure out one possible combination to a mixture, when there are over 100 possibilities. The 8th graders had to look at the physical and chemical properties, to somehow figure out the mixture. A group of students thinks that Baking Soda and Citric Acid is what’s in the mystery mixture. That group thinks that Baking Soda and Citric Acid is in it for a lot of reasons. One reason is that the mystery mixture has circular round objects in it and the Citric Acid is circular and round. Another one is that when you cut open the Citric Acid it’s crystal clear inside. The mystery mixture is also crystal clear inside when you cut it open. The fizz time of the mystery mixture and Baking Soda and Citric Acid were both roughly 11 minutes
