This lab is a CLASSIC and your students will love it! This is the easiest way that I have found to teach students about chemical and mechanical weathering. All you need: test tubes, small chunks of limestone, a balance, and a couple test tube stoppers. Personally, I LOVE lab investigations that require a few days of "waiting" in between setup and completion as students love to check on the progress of their limestone samples, and they look forward to "Day 2" of the lab. I have used this for years and it works! Have fun :)
The designed PDF can be enjoyed the way it is, but a straightforward editable word doc is included as well.
