This science lab has a paper version and a version that can be done over Google Documents.
I have my students get to the link of the document and then save a copy. Please do the same so you do not edit my version.
The URL to get to the Google Doc is on the paper copy version.
Students can type their answers in the Google Doc while doing their lab and then share their labs with you in real time.
This lab reviews density and runs through a few small experiments to teach the idea of density through inquiry and a 3e cycle.
