Moving Across the Membrane: Challenge Paper
An Olympiad-style paper: 10 questions in 20 minutes, +3 for a right answer and -1 for a wrong one. Diffusion, osmosis, the potato experiment and active transport. One asks you to choose a picture, and one reads a graph. Every answer has a worked solution that names the usual slip.
