A Resource for Free-standing Mathematics Qualifications Climate A The Nuffield Foundation 1 Photo-copiable Unit Advanced Level, Working with algebraic and graphical techniques Notes This is an adaptation of an activity that was written by Sylvia Knight (University of Oxford Atmospheric, Oceanic and Planetary Physics) and Jon Gray (Banbury School) for a Nuffield project linked to the climate prediction .net project. This version, Climate A, of the activity assumes students have access to Excel, but there is also an alternative version, Climate B, a paper-based activity requiring use of a graphic calculator. Either of the activities can be used independently, or students can use both – this would allow them to compare the methods used (useful for the Applying Mathematics part of the course). The work may be shared between students if you wish. The activity can also be adapted for use as an assignment, but in this case it is recommended that students are given less help than is currently written into the activity (to enable them to achieve high marks for their Coursework Portfolio by working independently). It is also advised that a different percentage increase and decrease are used to avoid the possibility of students using the answers given in these Teacher Notes. The incoming radiation can, for example, be decreased down to 20% or increased up to 200%. Prior knowledge needed Before using this activity students will need to have learnt how to use a spreadsheet to: write spreadsheet formulae involving both relative and absolute cell references; draw graphs; use trendlines to find polynomial regression lines. Note that if students know how to substitute data values into exponential functions and solve the resulting equations they could be asked to find their own exponential functions to model the temperature data.
