I took pictures of some other beverages to look at. I want the students to compare the ratios for each beverage of total sugar to number of sugar packets. I would like the students to graph them and find the constant of proportionality. Then I'm thinking I want them to find the rates of total sugar to number of ounces for each beverage. I plan on having them make comparisons using unit rates and then answer questions about how much milk they would have to drink to get the same amount of sugar as in a bottle of Coke, for instance.
Since I've never tried this kind of activity before, I'm looking for any feedback on issues I should plan ahead for and good ways of organizing such an activity. Any feedback on my plans to extend the investigation?
Thank you to anyone out there in the MTBoS that's willing to help me out!
One possible extension could be about the weight of sugar in each drink as compared to the liquid.
ReplyDeleteAlso, I think having the physical amount of sugar there, in addition to the video, would be a great way to illustrate the point.
For slightly older students, you could do the same with cigarettes and the amount of tar, etc...
I saw your post and thought I would love to do the same thing, then found Sarah's post here- http://mathequalslove.blogspot.com/2012/04/sugar-packets-and-proportions.html. I am creating an activity to go with it and I would be happy to send it along when I have it done. -Courtney
