    For everyone who needs to take observations for class :((( here:
    Once the Phenol Red was mixed into the other ingredients, the mixture began to fizz, followed by the color changing yellow. One end of the bag was hot and the other cold, because the liquid is endothermic. As the mixture continues to fizz, you can see there's an evolution of gas where the bag is swelling up. This chemical reaction has a generation of gas, its exothermic, endothermic and color changing. Another observation is, if you put your ear next to the bag you are able to hear the fizzing that is happening because of the chemical reaction. When water is added to the bag, an orange and red color begins to show.

    Did the mass changed after the reaction?

      Law of Conservation of Mass. Mass/Matter cannot be destroyed or created, so it obviously stayed the same. Hope it helped!

      According to Flinn Scientific's instructions for this experiment, "Calcium chloride, baking soda, and water [which is probably part of the phenol red solution] combine to produce carbon dioxide gas.

      The appearance of gas is a sign of a chemical reaction. When substances mix, they can create gas naturally as a part of the reaction.

    Yes, experiments are important, and should be introduced as early as possible. I very much appreciate that view of the teacher here. However, I think the design of this experiment is quite bad, to be honest. It is too chaotic. The things one can (potentially or hopefully) learn from this experiment could be much better taught with a differently designed experiment.
