Fifth graders are truly acting like scientists...wait, they ARE scientists!
The five mystery chemicals identities are still unknown at this time, and even though we combined them with drops of water, the mixtures didn't really tell us many distinguishable properties. Many were still sticky, gooey, and white. Some of the mixtures felt a little more grainy than others, but we still couldn't determine one from another distinctly.
So after creating a class properties table for the five chemicals, we had an in depth discussion as scientists do. Students suggested that maybe the six drops of water they used wasn't enough and that we should add more. Since only one of the chemicals dissolved, then maybe adding more would dissolve more of the chemicals?
So that began our series of tests today! We mixed each of the five unknown chemicals with 10 mL of water and stirred them for a total of a minute and a half. After letting them sit, we noticed that some "settled" more than others. We restirred them and sent them through filters to close out our lab, and we'll wait for tomorrow's results! Keep up the great work, scientists!
