This week we continued our Mixtures and Solutions unit. Students learned to use new tools, including: a balance, a screen, and a filter as they attempted to separate mixtures and get me back the materials we started with. At this point, 2/3 of the materials have been returned, including the gravel and the diatomaceous earth. We have set up evaporation dishes to attempt to retrieve the salt back from the sodium chloride and water solution. A few more days will determine if they were successful. It is looking good so far though!
