Onion Cells Lab
This is the beginning of an inquiry lab to find the salt content of onion cells. Throughout the lab, students will have a pre-investigation with water and a salt solution to demonstrate plasmolysis in plant cells. Once they've had this initial data, they will come up with their own hypothese of what they think the salt concentration of an onion cell is, and will then develop an experiment to test their hypothesis. By the end of the experiment, students will have discovered if their hypotheses were correct or not, and will have determined the salt concentration of a plant cell.
