Every GCSE Science sheet published in July 2014, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in July 2014
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st July 2014Name the four stages usually considered in a life cycle assessment of a product.
- 2nd July 2014A student says that metals conduct electricity because they contain free-moving ions. Explain why this statement is incorrect, and give the correct explanation.
- 3rd July 2014Convert 250 cubic centimetres into cubic decimetres.
- 4th July 2014A student heats solid copper carbonate strongly in a test tube, and it breaks down into copper oxide and carbon dioxide. Heating must be continued throughout the reaction for it to keep going. State whether this thermal decomposition reaction is exothermic or endothermic, and explain your reasoning.
- 5th July 2014Name the two industrial methods of cracking.
- 6th July 2014Write the formula for calculating an Rf value.
- 7th July 2014Readings have a mean of 20.0 cm and a range of 1.0 cm. Calculate the percentage uncertainty.
- 8th July 2014What happens to the total resistance when a second resistor is added in parallel, and why?
- 9th July 2014What happens inside the nucleus when a beta particle is emitted?
- 10th July 2014Explain, using Newton's Third Law, why a swimmer is able to push themselves forward by pushing backward against the water.
- 11th July 2014State what happens to the magnetic field around a straight current-carrying wire if the direction of the current is reversed.
- 12th July 2014State what red-shift shows about the motion of most distant galaxies.
- 13th July 2014State three factors that increase the rate of diffusion.
- 14th July 2014Which type of pathogen causes athlete's foot, a fungal skin infection?
- 15th July 2014State the word equation for aerobic respiration.
- 16th July 2014State one ethical concern raised by embryo screening.

- 18th July 2014What did the alpha scattering experiment show that the plum pudding model could not explain?
- 19th July 2014Magnesium is burned in an open crucible and the mass increases. Explain why.
- 20th July 2014State the name given to the negative electrode in electrolysis.
- 21st July 2014Explain why using a light sensor and data logger is more reliable than timing by eye in the disappearing cross practical.
- 22nd July 2014Describe the result of the test for carbon dioxide.
- 23rd July 2014Give one piece of evidence used to link human activity to recent climate change.
- 24th July 2014Give one advantage and one disadvantage of wind power.
- 25th July 2014Why does the temperature stay constant while a substance boils?
- 26th July 2014A box has a driving force of 250 N forward and friction of 180 N backward. Calculate the resultant force, including its direction.
- 27th July 2014Explain, in terms of particle motion, why a wave can transfer energy without transferring matter.
- 28th July 2014Name the region of the Solar System where most asteroids are found.

- 30th July 2014Name the substance in red blood cells that binds oxygen.
- 31st July 2014Explain why anaerobic respiration releases much less energy per glucose molecule than aerobic respiration.
