October 2022 - GCSE Science 5-a-day
Every GCSE Science sheet published in October 2022, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in October 2022
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st October 2022Why does a potometer measure water uptake rather than transpiration directly?
- 2nd October 2022Why does the rate of photosynthesis fall at very high temperatures?
- 3rd October 2022Define the term allele.
- 4th October 2022Explain why large-scale deforestation increases the concentration of carbon dioxide in the atmosphere.
- 5th October 2022State the four stages considered in a life cycle assessment.
- 6th October 2022Why does simple molecular carbon dioxide have a much lower melting point than giant covalent silicon dioxide?
- 7th October 2022Define oxidation in terms of electrons.
- 8th October 2022State two units that the rate of a reaction can be measured in.
- 9th October 2022Explain why carboxylic acids are described as 'weak acids'.
- 10th October 2022Explain why the natural greenhouse effect is necessary for life on Earth, rather than being a purely harmful process.
- 11th October 2022A 3 kg object is raised 2 m. Calculate the gravitational potential energy gained. (g = 9.8 N/kg)
- 12th October 2022State the correct SI unit for density.
- 13th October 2022A GM tube detects a count rate of 240 counts per minute from a source. After 15 days the count rate has fallen to 30 counts per minute. Show that this data is consistent with a half-life of 5 days.

- 22nd October 2022Name the three types of strong chemical bonding.
- 23rd October 2022State two reasons why a percentage yield is less than 100 percent.
- 24th October 2022State what is meant by the activation energy of a reaction.
- 25th October 2022Define the term 'hydrocarbon'.
- 26th October 2022Explain why the baseline is drawn in pencil rather than ink.
- 27th October 2022Give one reason for taking the gradient from the line of best fit rather than from two data points.
- 28th October 2022State the equation linking potential difference, current and resistance.
- 29th October 2022Define half-life.
- 30th October 2022A shopping trolley has a mass of 25 kg. Calculate its weight, taking g = 9.8 N/kg.
- 31st October 2022A student wraps a coil of insulated wire around an iron nail and connects it to a battery. Name the device this creates, and state one way to increase its magnetic field strength.
