Biology KS3/GCSE: Osmosis Rap
Science presenter Jon Chase describes the difference between a ‘selectively permeable’ and ‘partially permeable’ membrane, as well as the terms ‘crenation’ and ‘lysis’.
In doing so, he performs a rap about the basics of osmosis.
Ask students to list the similarities and differences between diffusion and osmosis.
Students could then complete a practical exercise to measure the change in mass of small sections of raw potato when placed into distilled water and different concentrations of sugar.
These short films will be relevant for teaching biology and science in general at KS3 and KS4 in England, Wales and Northern Ireland and National 4/5 in Scotland.
