This is a guided lab as part of a series. Students examine yeast for signs of life based on the characteristics of living organisms. In this first lab, students look for the excretion of waste, specifically carbon dioxide using the indicator Bromothymol Blue (BtB) solution.
Later in the series, students become more and more independent to design their own investigations, construct data tables and support argument using evidence. I also offer a package with a calendar and additional instructional tools.
