B4g: Decay
We try to prevent food going off (decaying) but we want decay to happen when sewage is treated or when compost is made. This item is concerned with the process of decay and some examples. The experiments on decay provide the opportunity to plan a test of a scientific idea, analyse and interpret data using qualitative and quantitative techniques, present information and draw a conclusion using scientific and technical conventions. The survey of preservation techniques provides the opportunity to use ICT sources and tools to collect secondary data.
