we put one spoon full of baking soda and calcium chloride in one side of the bag and tied it off from the other corner with the pipette of phenol red then we shook and mixed them well. it turned yellow and it was bubbly and foamy and it was cold and the bag popped because it filled up with air and it smelled like rubbing alcohol.

1. baking soda and phenol red made it cold
2.calcium chloride and phenol red made it hot
3.orange. what made the color change was the calcium chloride and the baking soda and phenol red made it turn orange.
4.the temperature started to change right when the chemical touch the color change a little bit after that.
5. All of the experiments required a liquid for a reaction to occur in the bag.
6. Gas is the new substance formed when all chemicals are mixed in the bag. Chemicals responsible are both the solids and water.
7. An experiment that could be tested is to add different amounts of water to see if calcium chloride's looks would change.
8. A temperature isn't the only change that indicate a chemical reaction because their is also the physical change and the smell.
