I think if you put it in cold water nothing will happen. ...Haley I think warm water because warm water melts sugar. ...Ricki |
Our Procedure: We got two beakers of water, one
hot and one cold. We put the sugar lumps in the glasses.
We kept track of the time and saw which dissolved faster.
...Kailani First we got a cup with hot water and then we got a cup with cold water. We took the temperature of the water in each glass. then we dropped a sugar cube in each class and made our observations. ...Joe F. |

Thoughts on doing
experiments:
The exsperment was fun because everyone worked together.
We worked together by not fighting and taking turns. ...
Karl I like doing the exsperiments because they take brains to think about the questions. I really liked the exsperiment when we put the vinegar in the bottle and put the baking soda in the bottle. ...David I like doing these things because it's fun and you learn stuff that you might have not known. Even if you are doing experiments like dropping an ice cube in pop and watching it dissolve and turn into a liquid it's fun. It's fun to be a scientest sometimes. ...Alex I think expirements are fun. They help you understand the process better. They also help you fill out lab sheets better and not have so many questions. ...Ashley S. I like exsperments because time goes very fast. ...Brandon |
