In this activity, students are expected to recognize and identify components of a cell membrane as well as construct a membranes correctly using cutouts of the components. After identifying and building the cell membrane, students will be given a set of “concentration situations” that they must set up using the cutout pieces. They will then use the labeled arrow cutouts to show what movement will take place in that specific situation. In this manipulative activity, they will model the following types of movement: diffusion, facilitated transport, active transport, and osmosis.
This is a great hands-on activity that helps students conceptually understand the different types of movement across a cell membrane. Membrane transport is such an intangible idea because it happens on such a small scale. This interactive lesson turns membrane transport into a tangible concept. It helps students conceptually understand osmosis, a concept that students traditionally struggle with. This is an excellent lesson for your visual, kinesthetic, and English Language learners. In addition to the manipulative cutouts, there is also a student assessment sheet, a key, and ample teacher instructions with diagrams to help explain the activity.
• Print and copy student assessment page (1 per person)
• Print in color membrane manipulative cutouts (1 set per group of 2)
• Laminate, cut and place cutouts in bags (Cutting instructions: Cut the lipid layers out as two long pieces. Cut all other pieces out individually.)
