Today students used their data from yesterday's experiment (the Newton's finished today) to determine what the Mystery Chemical was from a given Chemical Data Sheet. Students had to use what they knew about solubility to prove their answers. This assessment goes towards our "Materials Identification" target.
Next week, we will be looking at the crystal left behind from our citric acid and "mystery chemical" solutions to see if we can use that property to distinguish between chemicals. We will be doing a fun activity with super saturated solutions next week- Thursday or Friday. Students will be learning about how temperature affects solubility and then seeing in real life how that works. For this activity, each student needs to bring in a glass jar to use for their solution. They will bring them home during the last week before vacation. Additionally, I will need one box of Borax soap per homeroom- Arbour's homeroom is all set because one was brought in today.
