Mystery Canisters and the Sunday Search
Remember the days of 35 MM film? And those film canisters that the film came in?
Well, there are many fun labs that one can do with these canisters. (read: labs that could be done with other materials too, but the canisters are FREE, and teachers LOVE free)
Anyway, I am doing a mystery canisters lab soon with my 6th grade crew, during which they have to design canisters that will sink, float, and "suspend" in water. I need a total of 35 canisters. Yesterday, I must have gone to 6 different Targets, Walgreens, and CVS pharmacies. They were very nice about allowing me to dig through their recycling, but all I came up with so far were 20 canisters!
Luckily, I started early. In a plea to get some from parents, I posted it on my homework website. Who knew these would be so hard to come by. I guess it makes sense given that so many now shoot digital....
