AQA GCSE Combined Science 8464 / Combined Science 8461 4.4.2.1 Aerobic and Anaerobic Respiration PRACTICAL: Suggested Starter: Draw a diagrma of a plant cell (F) Label a diagram (F). Which cells might have the most mitochondria (give examples of cells and geroup work or debate). Main Activity: Set up the experiment and get pupils to complete this at different temperatures per group, then get pupils to try different tempertures. Collect the data as a class. Identify the control variables in the experiment as a class at the beginning to make sure all data is valid. Pupils could either complete a graph of the experimental results and interpret this and evaluate the experiment (H). Pupils are collecting data and bringing this together, so those that work faster or take time to wait for the experiment to work will need some data or questions to work on as they are going through this. Use the visualiser to compare different pupils graphs. Write an explanation of how the experiment works, linking this to the equation for respiration and the absorbtion of carbon dioxide by the sodium hydrogen carbonate. Suggested Plenaries: draw a diagram of a mitochodria and show what goes in and out. Write a definition of aerobic respiration and correct as a class. Suggested Starter: Compare aerobic and anerobic repsiration in a table. Demonstrate resiration in yeast , possibly at different temperatures. Ask them to write the differences between this experiment and the one carried out from last time (no sodium hydrogen carbonate used, only carbon dioxide). Give the equation for anaerobic respiration in animals and yeast and ask studetns to list similarites and differences. Main activties: (optional): Investigate the rate of respiration in yeast using carbon dioxide. Interpret graphs on the respiration of yeast cells. Compare aerobic and anaerobic respiration in a table. Suggested Plenaries: question race game between two sides of the class (different groups) on topics for respiration in general.
