August 2006 - GCSE Science 5-a-day
Every GCSE Science sheet published in August 2006, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in August 2006
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st August 2006Where in a plant are stem cells found?
- 2nd August 2006Name the process by which dissolved sugars are transported in the phloem.
- 3rd August 2006Why is photosynthesis described as endothermic?
- 4th August 2006Define the term allele.
- 5th August 2006State one human activity that reduces the amount of land available for other organisms.
- 6th August 2006State the two substances that must both be present for iron to rust.
- 7th August 2006State the size range of a nanoparticle.
- 8th August 2006Why is aluminium extracted by electrolysis rather than by reduction with carbon?
- 9th August 2006Explain, using collision theory, why increasing the concentration of a reactant in solution increases the rate of a reaction.
- 10th August 2006Explain why carboxylic acids are described as 'weak acids'.
- 11th August 2006Explain why the natural greenhouse effect is necessary for life on Earth, rather than being a purely harmful process.
- 12th August 2006What happens to the energy described as 'wasted' in a transfer?
- 13th August 2006State the correct SI unit for density.
- 14th August 2006Explain the difference between irradiation and contamination.
- 15th August 2006Explain why ultraviolet radiation can be harmful to human skin.
- 16th August 2006State two ways of inducing a potential difference across a conductor using a magnetic field.
- 17th August 2006Convert 0.02 mm into micrometres (um).
- 18th August 2006Name the products of protein digestion.
- 19th August 2006State the difference between an antibiotic and a painkiller.
- 20th August 2006A ruler is released and falls 20 cm before being caught. Using distance = 0.5 x g x time^2 with g = 9.8 m/s^2, calculate the reaction time, to 3 significant figures.
- 21st August 2006Name the equipment used to measure the abundance of a small plant species within a sample area.
- 22nd August 2006State one benefit of recycling metal rather than extracting new metal from its ore.
- 23rd August 2006Name the three types of strong chemical bonding.
- 24th August 2006Convert 250 cubic centimetres into cubic decimetres.
- 25th August 2006A 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.
- 26th August 2006Define the term 'hydrocarbon'.
- 27th August 2006Write the formula for calculating an Rf value.
- 28th August 2006Readings have a mean of 20.0 cm and a range of 1.0 cm. Calculate the percentage uncertainty.
- 29th August 2006What happens to the total resistance when a second resistor is added in parallel, and why?
- 30th August 2006What happens inside the nucleus when a beta particle is emitted?
- 31st August 2006A shopping trolley has a mass of 25 kg. Calculate its weight, taking g = 9.8 N/kg.
