The Pearson Edexcel A-level Biology A (Salters Nuffield) specification states that a minimum of 10% of the marks across the assessment papers will require the use of mathematical skills. This revision lesson has been designed to include a wide range of activities that challenge the students on these exact skills because success in the maths in biology questions can prove the difference between one grade and the next!
Step-by-step guides are used to walk students through the application of a number of the formulae and then exam-style questions with clear mark schemes (which are included in the PowerPoint) will allow them to assess their progress. Other activities include differentiated tasks, group discussions and quick quiz competitions such as “FROM NUMBERS 2 LETTERS” and “YOU DO THE MATH”.
The lesson has been written to cover as much of the mathematical requirements section of the specification as possible but the following have been given particular attention:
- Hardy-Weinberg equation
- Chi-squared test
- Calculating size
- Converting between quantitative units
- Standard deviation
- Estimating populations of sessile and motile species
- Percentages and percentage change
- Cardiac output
Due to the detail and extensiveness of this lesson, it is estimated that it will take in excess of 2/3 hours of A-level teaching time to work through the activities and it can be used throughout the duration of the course
