In the Diffusion Osmosis Inquiry Lab Solution for AP® Biology, students participate in two baseline activities that branch out with opportunities for inquiry during which a hypothesis is formed, tested and justified.

Includes access to exclusive FlinnPREP™ digital content to combine the benefits of classroom, laboratory and digital learning. Each blended learning lab solution includes prelab videos about concepts, techniques and procedures, summary videos that relate the experiment to the AP® exam, and standards-based, tested inquiry labs with real sample data. FlinnPREP™ Inquiry Lab Solutions are adaptable to you and how you teach with multiple ways to access and run your AP® labs.

Big Idea 2, Investigation 4, Science Practices 2, 4, 5

How do cell membranes help regulate internal cellular makeup? In this Inquiry Lab Kit, students participate in two Baseline Activities that branch out with Opportunities for Inquiry during which students will develop a testable hypothesis and then design an experiment that they can plan, discuss, evaluate, execute and finally justify to their peers.

In the first Baseline Activity, students study the diffusion of ions into a model cell. Questions like, “How does the rate of diffusion influence the ability of a cell to obtain needed nutrients?” and “How might the surface area-to-volume ratio affect the rate of diffusion into a cell?” help guide the students to design their own experiments. In the second Baseline Activity, students test the ability of various substances to diffuse across a semipermeable dialysis membrane and analyze results to identify solutions as hypotonic, hypertonic or isotonic. Students use these observations and guiding questions like, “Is the rate of diffusion directly proportional to the solute concentration?” and “How would diffusion of a starch solution be different than that of a protein?” to develop their inquiry experiments.

Includes detailed teacher notes, reproducible student handouts and enough materials for eight groups of students to complete the Baseline Activities and to prepare for the inquiry activities. A 0.01-g precision balance is required and available separately. A refill kit for the Diffusion and Osmosis Inquiry Lab Kit for AP® Biologyis also available (FB2086).

FLINNprep is just one of the powerful learning pathways accessed via PAVO, Flinn’s award-winning gateway to standards-aligned digital science content paired with hands-on learning.
