May 2011 - GCSE Science 5-a-day
Every GCSE Science sheet published in May 2011, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in May 2011
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.

- 3rd May 2011Define the term 'wavelength' of a wave.
- 4th May 2011State the difference between an alternator and a dynamo.
- 5th May 2011A microscope has a x10 eyepiece lens and a x20 objective lens. Calculate the total magnification.
- 6th May 2011Name the products of protein digestion.
