Topic 7 Practical Ideas
Topic 7 Practical Ideas
There are few labs and practical activities which lend themselves to Topic 7. In the Swiss Alps we even managed to do a succession study, post glacial retreat in a couple of locations.
I've already included a couple of relevant labs elsewhere. Try looking at the relationship between water temperature and dissolved oxygen Water Temperature and Dissolved Oxygen, the radiative forcing of greenhouse gases Greenhouse Gases Radiative Forcing Effect, and the Impact of Burning Vegetation.

7.2 Greenhouse Gases Radiative Forcing Effect
Greenhouse gases have a positive radiative forcing effect on atmospheric temperature. Radiative forcing is the difference between the incoming solar radiation and the amount of energy radiated back. We...
7.2 Modelling the Albedo Effect 1
Different land surfaces have different albedo. Dark surfaces absorb light while lighter surfaces reflect more light. There is a nice youtube video showing how different coloured ice melts at different...
7.2 Ocean Acidification
As this topic has become more prevalent in the news, more students have expressed an interest in investigating it experimentally. One student extended this topic into her Biology extended essay. For a...
7.2 Viewpoints on Climate Change and Solutions
Before starting to design a questionnaire for this investigation you should check out this advice Designing Surveys and Questionnaires. This topic is a real minefield of opinions, politics, religion...
