I have contributed to investigations into the role of microorganisms in producing and breaking down some materials. 

SCN 2-13a

Benchmarks:

·  Demonstrates understanding of how microorganisms, including bacteria, viruses and fungi, can multiply rapidly.

·  Investigates and explains the action of some microorganisms used in food production, for example, yeast in bread and bacteria in yoghurt.

·  Describes how some micro-organisms break down food causing it to be inedible or harmful if digested, and how others exist in the gut to break down food to aid digestion.

·  Investigates, observes and records how microscopic organisms are necessary for the process of decomposition (the breaking down of dead material – decay).
