December 2014 - GCSE Science 5-a-day
Every GCSE Science sheet published in December 2014, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in December 2014
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st December 2014State two long-term stores of carbon that removed carbon dioxide from the early atmosphere.
- 2nd December 2014A 3 kg object is raised 2 m. Calculate the gravitational potential energy gained. (g = 9.8 N/kg)
