December 2012 - GCSE Science 5-a-day
Every GCSE Science sheet published in December 2012, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in December 2012
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st December 2012State the difference between an antibiotic and a painkiller.
- 2nd December 2012Name the two parts of the central nervous system (CNS).
- 3rd December 2012Name the group of organisms that break down dead plant and animal matter, returning mineral ions to the soil.
