Weather Tools

In our class everybody had to do a weather tool and four people did thermometers. Anik made his with alcohol and tap water. Andrea did hers with cooking oil. Fred and Nicole did there’s with water. So we went to the teachers lounge and we put them in a bowl of cold water and a bowl of hot water. Anik did it first in the cold water and the liquid in the straw went all the way down into the bottle .Fred did it first in hot water and it didn’t go up. We think it did not go because there was a plug in the top of the straw . Then Andrea did it in hot water second and it went up alot. Nicole did it in hot water and it went up a little. Then we put Andrea's in the cold water and it went down a little bit maybe because the oil is dense. Then Anik put his in the hot water and it almost exploded!!! We had a lot of fun doing our experiments on our thermometers.
