May 2023 - GCSE Science 5-a-day
Every GCSE Science sheet published in May 2023, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in May 2023
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st May 2023Convert 0.05 mm into micrometres.
- 2nd May 2023State the function of the valves in the heart and in veins.
- 3rd May 2023State three factors that can limit the rate of photosynthesis.
- 4th May 2023Explain why type 1 diabetes is treated with insulin injections rather than tablets.
- 5th May 2023The Arctic fox has small, rounded ears compared with the desert fennec fox, which has very large ears. State whether this is a structural, behavioural or functional adaptation, and explain how it helps the Arctic fox survive.
- 6th May 2023Explain, in terms of particle size, how reverse osmosis separates water from dissolved salt.
- 7th May 2023Write the formula of calcium chloride and explain the ratio.
- 8th May 2023Explain why aluminium cannot be extracted from aluminium oxide by heating with carbon.
- 9th May 2023Hydrogen reacts with chlorine to form hydrogen chloride: H2 + Cl2 -> 2HCl. Use the bond energies given to calculate the overall energy change for this reaction. Bond energies: H-H = 436 kJ/mol, Cl-Cl = 243 kJ/mol, H-Cl = 432 kJ/mol.

- 16th May 2023State two ways of increasing the force produced by a motor effect setup, for a wire of fixed length at a fixed angle to the field.
- 17th May 2023Why does taking repeat readings and calculating a mean improve the data?
- 18th May 2023Name the plant tissue that transports water and dissolved minerals from the roots to the leaves.
