For this lab, we needed these supplies:
-Pipette of Phenol Red
-Pipette of Water
-Spoonful of Sodium BiCarbonate
-Spoonful of Calcium Chloride
-Ziploc Bags
-Safety Glasses
Safety Concerns:
-Phenol Red stains clothing.
-WEAR SAFETY GLASSES!!!
-Do not sniff anything, only waft.
-Do not eat anything.
Descriptions:
-Phenol red is a red liquid that can stain clothing.
-Calcium Chloride is white and in little chunks.
-Sodium bicharbonate is a white, soft powder.

Experiment 1:
We mixed all of the necessary supplies together in a small ziploc bag. The "dry" products were put in one corner of the ziploc bag and the liquids were put in the other corner. (The video shows this better). After all the supplies were put in the bag, we shook the bag and made sure all of the supplies got mixed together. As we were doing this, we observed different physical changes, for example, color, temperature, a gas was produced, etc. A video will be posted later in the blog to show this experiment.
After Experiment 1, we did two other experiments to test which components did what physical reaction in the experiment.
Experiment 2:
We mixed phenol red, water and calcium chloride together in one bag. Following the same steps as the first experiment, we then shook the supplies together and recorded observations. Again, the video will be poster later in this blog to show exact physical changes.
Experiment 3:
We went along the same process of experiment two, but instead we put phenol red, water and sodium bicarbonate together. A video will be posted to show the physical changes.
