November 2004 - GCSE Science 5-a-day
Every GCSE Science sheet published in November 2004, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in November 2004
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st November 2004Name three non-specific defences of the human body.
- 2nd November 2004A 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.
- 3rd November 2004Name the equipment used to measure the abundance of a small plant species within a sample area.
- 4th November 2004State the two main steps used to produce potable water from a fresh water source.
- 5th November 2004State the charge on a calcium ion (Group 2).
- 6th November 2004Convert a concentration of 0.20 moles per cubic decimetre of NaOH into grams per cubic decimetre. (Mr = 40)
- 7th November 2004State the energy transfer that occurs during an exothermic reaction.
- 8th November 2004Define the term 'hydrocarbon'.
- 9th November 2004In a chromatography experiment, a dye spot travels 4.5 cm and the solvent front travels 6.0 cm. Calculate its Rf value.
- 10th November 2004Define the resolution of a measuring instrument.

- 14th November 2004A 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.
- 15th November 2004Explain 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.
- 16th November 2004Why does active transport require energy?
- 17th November 2004Name the vector that spreads the protist pathogen that causes malaria.

- 19th November 2004A man has genotype XY. State his sex, and state which sex chromosomes are found in the sperm cells he produces.
- 20th November 2004Name one way to make a rate of reaction experiment more valid rather than simply more precise.
- 21st November 2004Define an isotope.
- 22nd November 2004A sealed flask containing 12.0 g of reactants is shaken and a reaction occurs. What is the total mass afterwards?
- 23rd November 2004In the industrial extraction of aluminium, explain why the aluminium oxide is dissolved in molten cryolite rather than melted on its own.
- 24th November 2004Explain why increasing the surface area of a solid reactant increases the rate of a reaction.
- 25th November 2004State the difference between a pure substance and a formulation.
- 26th November 2004Explain why burning a fuel can produce nitrogen oxides even if the fuel itself contains no nitrogen.
