CHEMISTRY: Great job today… although, it was kind of weird watching you chew gum in class!
Lab reports are due Saturday midnight – to be saved to your Google Dropbox as a PDF. Double check your calculations, sig figs, etc. Remember you are finding the percent of SUGAR in gum, so that means the mass of what goes on top? Show all your data – everything you measured, and everything you calculated. And don’t forget the conclusion!
BTW – I think you’ll find that percent composition problems are really easy to catch on to. Make sure, though, you can write chemical formulas (I won’t give them to you!) and that you’ve memorized the formulas for acids and those chemical names for common substances so that you’ll have something to find the percent composition of!

I really enjoyed the bubble gum lab today!!
That lab was way easier than I anticipated! I had no idea sugar made up that much mass of gum!
I’m really glad percent composition is easly and not awfully difficult. Hope to have more labs like it 🙂
Really missed you today
I thought it was really cool how we found how much grams of sugar were in a piece of gum!
It was nice to be able to chew gum in the name of science and find the percent composition of the sugar in the gum by dissolving the sugar in our mouths.
I enjoyed chewing gum and finding the percent composition of sugar in gum!
thanks for posting the lessons. I will be back on tuesday.
I really liked the gum lab this week!
Thank you for posting this! I really enjoy finding percent composition!
This weeks labs were really fun. Who knew math and chemistry could be so fun!
The labs this week were really fun.
I like the empirical formula problems. I really understand them.
I remember this lab! So much fun and easy to understand too(: Hope y’all have fun with this
