Summer SAVY Session 2, Day 3 – Common and Practical Chemistry (Crooke)
Day 3: We started the morning by classifying chemical compounds as ionic or covalent. We then learned to make solutions. Each group made a solution with a different concentration of Copper II Sulfate, an ionic compound. We then heated the solution to dissolve all the chemicals and then poured it into a dish so that it could form crystals. We have been looking at the crystal formation throughout the day and will examine the results tomorrow morning. Our focus then turned to acids and bases. We learned about pH and that we all have acid breath. Our breath was used to blow into a basic solution and turn it from pink to clear, indicating that the solution had changed from basic to neutral. After lunch, we stayed in the Wyatt building to make lemonade. Students were able to choose and make five different concentrations of lemonade to determine which one tasted best. Finally, we finished our day with the slime of the day. Once again, we altered the recipe to make clear baking soda slime with glitter.
