Edvotek™ Advanced Placement Laboratory Kit 1: Principles and Practice of Diffusion and Osmosis
Experiments help students develop an understanding of the molecular basis of diffusion and osmosis and its physiological importance.
Manufacturer: Edvotek™ 281
- Analyze how solute size and concentration affect diffusion across semi-permeable membranes and how these processes affect water potential
- Calculate water potential of plant cells
- Class size: 40 students working in groups of 4
Part B: Experiment approximates an osmotic system by demonstrating net flow of water through a dialysis membrane.
Part C: Involves the calculation of potato cell water potential from experimental data.
†Beakers can be substituted with clear, disposable plastic cups.
Class size: 40 students working in groups of 4.
