Today, we started class today by continuing working on this question:
In small groups, you will devise a plan on how to separate the following frozen mixture of sawdust, iron fillings, sand, and sugar.
Ever group discussed with there tables about how they are going to separate these.
Our group said that we would melt the ice cube in a glass container. The less dense material (wood) will be floating and we will scoop it out. Then we will use a magnet to attract the iron filling out of the water. Then we will pour the water, sand, and sugar mixture through a coffee filter and into a glass container so the sand and water/sugar is separated. After that, we will heat the water/sugar mixture. We predict that by doing this, the water will evaporate and the sugar would stay in the glass container.
After we came up our own experiments, we performed it. This experiment has to be done within the class period.
When performing our experiment, we were very careful when heating the water with dissolved sugar. Another group heated the water/sugar for too much and had the same outcomes as our sugar lab. I am not really sure about how to prevent this. Is there a certain temperature that sugar separates to carbon and water?
