June 2016 - GCSE Science 5-a-day
Every GCSE Science sheet published in June 2016, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in June 2016
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st June 2016Explain why the rate of an enzyme-controlled reaction decreases sharply above the enzyme's optimum temperature.
- 2nd June 2016Give one way of reducing the spread of malaria.
