June 2026 - GCSE Science 5-a-day
Every GCSE Science sheet published in June 2026, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in June 2026
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st June 2026Define electric current.
- 2nd June 2026A source has a half-life of 5 days and an initial activity of 1600 Bq. What is its activity after 15 days?
- 3rd June 2026A shopping trolley has a mass of 25 kg. Calculate its weight, taking g = 9.8 N/kg.
- 4th June 2026A 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.
- 5th June 2026Explain why red-shift observations support the idea that the universe is expanding, rather than Earth simply being at the centre of the universe with everything moving away from it.
- 6th June 2026Calculate the surface area to volume ratio of a cube of side 2 cm.
- 7th June 2026Name the vector that spreads the protist pathogen that causes malaria.
- 8th June 2026Explain, in terms of respiration, why a build-up of lactic acid causes muscle fatigue during vigorous exercise.
- 9th June 2026A man has genotype XY. State his sex, and state which sex chromosomes are found in the sperm cells he produces.
- 10th June 2026Give the resolution of a burette that can be read to the nearest half of a small division.
- 11th June 2026Why is an atom electrically neutral?
- 12th June 2026State the law of conservation of mass.
- 13th June 2026In the industrial extraction of aluminium, explain why the aluminium oxide is dissolved in molten cryolite rather than melted on its own.
- 14th June 2026Explain why increasing the surface area of a solid reactant increases the rate of a reaction.
- 15th June 2026Give one piece of evidence that a solid sample is impure, based on its melting behaviour.
- 16th June 2026Explain why carbon monoxide is dangerous even though it has no smell.
- 17th June 2026Why can no device be 100 percent efficient?
- 18th June 2026Why is melting described as a physical change?
- 19th June 2026A gardener pushes a mower with a force of 60 N through a distance of 8.0 m. Calculate the work done. Use W = F x s.
- 20th June 2026A wave has a frequency of 50 Hz. Calculate its period.
- 21st June 2026Explain, in terms of forces, why an orbiting satellite does not travel off in a straight line.
- 22nd June 2026Convert 0.05 mm into micrometres.
- 23rd June 2026State the function of the valves in the heart and in veins.
- 24th June 2026Name the organelle in a plant cell where photosynthesis takes place.
- 25th June 2026State one risk factor linked to type 2 diabetes.
- 26th June 2026The 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.
- 27th June 2026Name one method used to sterilise fresh water during the production of potable water.
- 28th June 2026Write the formula of calcium chloride and explain the ratio.
- 29th June 2026Write the word equation for the reaction between zinc and hydrochloric acid.
- 30th June 2026Hydrogen 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.
