August 2017 - GCSE Science 5-a-day
Every GCSE Science sheet published in August 2017, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in August 2017
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.

- 16th August 2017Explain why electricity is transmitted through the National Grid at a very high voltage rather than at the voltage used in homes.
- 17th August 2017Name the structure in a plant cell that controls the substances entering and leaving the cell.
- 18th August 2017Name the products of protein digestion.
- 19th August 2017State the difference between an antibiotic and a painkiller.
