Students will work in groups to create a Cartesian diver and answer questions about how density affects the movement of the diver, use 2 elements & 2 compounds to demonstrate their knowledge of elements, mixtures & compounds, calculate the density of a block and find their percent error, and create a density column after looking up the density of 5 different liquids.
This is a great summative activity or could be broken up into parts and used separately. I have it set up with each activity at each student lab bench, but you could turn this into stations easily.
