This is a lesson designed to meet specification points for the new OCR GCSE (Gateway) Biology 'Cell-level lsystems’ scheme of work.
The lesson begins with a recap from the last lesson, children are shown images of pieces of equipment which could be used to measure the rate of photosynthesis. Students can discuss, and write down in their books, a simple method using the equipment pictured. They can then self-assess their answers using the answer provided on the PowerPoint.
Children will now be given a worksheet which describes an experiment carried out to test the effect of carbon dioxide concentrations on the rate of photosynthesis. Students will need to plot a graph to represent the results, and then answer questions about this data.
Lastly, students will be introduced to the idea of the inverse square law - when you double the distance from a light source, the light intensity falls by a factor of four. Students will then need to use this to answer some questions in their books.
