SCN 3-05a
By contributing to experiments and investigations, I can develop my understanding of models of matter and can apply this to changes of state and the energy involved as they occur in nature.
Ion Migration (Demo) – Diffusion of lead nitrate and potassium iodide – yellow lead iodide precipitate at boundary.
Diffusing precipitates – microscale – a microscale version of the above experiment (and some similar ones) which enables the concept to be put across by pupil experiment rathern than demonstration.
SCN 3-05b
I can explain some of the processes which contribute to climate change and discuss the possible impact of atmospheric change on the survival of living things.
When a Fossil Fuel is Burned (Demo) – Collection of water and carbon dioxide when a Bunsen burns.
