1. Does hot water or cold water freeze faster?
Hot water freezes faster than cold water.
2. Does hot water or cold water boil faster?
Hot water boils faster than cold water.
3. Does salt water freeze faster or slower than regular water?
Regular water freezes faster than salt water.
My experiment was to see if Kool-Aid added into water made it freeze faster than regular water. I also tried Crystal Lite Lemonade in a seperate ice cube tray.
Questions for Activity One:
1.
2. My hypothesis was that with the substances added, the Kool-Aid and the lemonade would freeze slower than regular water.
3. The graph will be in a picture that will be uploaded onto the blog.
4. After testing this 2 seperate times, I did recieve the same answers, and found my hypothesis to be wrong. (again, graph will be in a picture uploaded)
5. My controlled variables were the regular water, and the temperature of the freezer in which my fridge was set at.
6. Looking at my hypothesis and my results, I found that the correct theory coming out of this was that regular water does not freeze faster than Kool-Aid and lemonade, it is in fact the same time.

This is a visual of the atoms that make up a water molecule.8. http://youtu.be/_bDLwsAwnTw
this is a link that talks about the 3 different states of water.
9. Scientific method steps:
-ask question: this is where I first realized what I wanted to experiment with, and what I was going to do.
-do research: I looked up the contents of each substance and that helped me form a hypothesis.
-construct hypothesis: this is where I made my first educated guess on what the outcome would be of my experiement.
-test: I conducted the experiment.
-analyze: I figured out if my hypothesis was right or wrong, and I also did testing a couple times to make sure I got the same results.
