Blog # 4(Reflection)
In AP Bio class, this week we were learning about the pH level and the pH scale. the experiment we did this week was to find out what pH range can Elodea plant survive in. We used the pH papers, the Elodea plant, and Solutions to see how they would effect the plant. The plant survive and was in a good condition when it was added to the water which was the normal pH range (7). But it died in some of the solution because they were too strong and too week. I learned that water is the best solution for plants and for human as well.

This week we were dealing a lot with chemistry and how is it effect our life. we did a lab to taste and see if the water a universal solvent. I learned that water is a great solvent, because it can dissolve the most type of substances.This is because solutes for the most part are able to dissolve in water with the exception of some solutes like oil. I have learned a lot this week about water and makes it a great universal solvent.
