AO3 – develop and refine practical design. Learning objective Time Learning Outcome Learning activity with opportunity to develop skills Assessment opportunities Resources The movement of water across partially permeable membranes by osmosis. The concept of water potential. 0.4 weeks Define osmosis in terms of water potential. Explain the movement of water due to osmosis into or out of cells. Explain the effect of osmosis on plant and animal cells. Learning activities: teacher explanation of osmosis and potential to arrive at an A-level definition jigsaw learning: working in teams of three, one student goes to each information station to discover about the effect of placing plant and animal cells in solutions with different water potentials (the terms hypotonic, hypertonic and isotonic are not specification terms) students feedback to one another teacher assessment and explanation to address of weakness exam questions. Past exam paper material: HBI3T 2014 EMPA Students could undertake the BIO3T ISA P from 2012 Rich question: Present diagrammatic representation of cells with numerical water potentials and ask students to represent the net movement of water with arrows between cells.
