Student Activity Kit, STEM Investigation, Is Yeast Alive?

How do scientists know if something is alive? There are certain characteristics of all living things that the scientific community uses to judge whether something is alive. On first observation, yeast does not look like a typical living thing. In this activity, students will hypothesize about yeast and then test to see if their hypothesis is correct. Using this information, they will be able to come to a conclusion to the question of whether yeast is alive. Kit contains enough materials for 15 groups. Teacher's Guide and Student Study Guide copymasters are included.
