| Dissolving M&Ms (sugar) in water & alcohol |
It's been a while since I've checked in about our chemistry class this year! Over the last month we've played with dissolving salt and sugar in water, alcohol and oil. We've discovered how the polarity of molecules affects how quickly the molecule can dissolve salt or sugar (if it can dissolve it at all). Here's Mane in action:

We have continued to be very happy with MiddleSchoolChemistry.com! It's taken a lot longer to work through the lessons that I thought it would because we are doing every experiment and project in the lessons unless we absolutely cannot find materials. The early lessons were a breeze. The later lessons are more dense, and both Mane and I are getting a lot out of them! I'm understanding chemistry a lot better than I did in college!

Do you mind sharing the link to the one that involved making crystals with salt and sugar?
It is not a lab to make salt & sugar crystals. It is a lab to look at salt & sugar crystals with a magnifying glass and then dissolve them in water, testing rates of solubility. If you leave the glasses sitting out, the water will evaporate and crystals will forms again, if that's the sort of thing you're looking for.
