Students will distinguish between descriptive, comparative, and experimental investigations.

Given investigation scenarios and lab procedures, students will identify independent variables, dependent variables, constants, and control groups.

The focus of this resource is cell homeostasis and, more specifically, osmosis. Students investigate the concept through a virtual lab, recording and analyzing data, creating sketches to represent vocabulary, and discovering the role of aquaporins in water transport through the cell membrane.
