Our demo was on pH. I believe our presentation went well. It wasn't the most exciting presentation but I think people stayed awake.


1. I learned that by adding salt to water it allows items such as an egg to float.

2. I learned the difference between mixture and solution. Mixture being two substances which never really combine. Solution is two substances that become one.

3. I learned what adhesion and cohesion is and how it works.

4. I learned that salt water is more conductive than any other water.

5. I learned that a balloon with water will not pop, but without it will.
