Module 7: Gradient & Barriers: Passive
Students explore passive diffusion and osmosis. By adjusting parameters of the system, such as permeability of the membrane or particles concentration, students can learn to predict the resulting flow of water or dissolved materials. They can explore a model of an erythrocyte in hypotonic or hypertonic solutions.
Objectives and Goals
Students will be able to:
AAAS: THE LIVING ENVIRONMENT: CELLS - Every cell is covered by a membrane that controls what can enter and leave the cell.
THE LIVING ENVIRONMENT: CELLS - The work of the cell is carried out by the many different types of molecules it assembless, mostly proteins.
THE PHYSICAL SETTING: THE STRUCTURE OF MATTER - The rate of reactions among atoms and molecules depends on how often they encounter one another, which is affected by the concentration, pressure, and tempoerature of the recting materials.
Life Science: The Cell - Cells have particular structures that underlie their functions.
