May 2013 - GCSE Science 5-a-day
Every GCSE Science sheet published in May 2013, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in May 2013
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st May 2013State the four stages considered in a life cycle assessment.
- 2nd May 2013Why does simple molecular carbon dioxide have a much lower melting point than giant covalent silicon dioxide?
- 3rd May 2013Define oxidation in terms of electrons.
- 4th May 2013State two units that the rate of a reaction can be measured in.
- 5th May 2013Name the two methods used to produce ethanol industrially.
- 6th May 2013Explain why the natural greenhouse effect is necessary for life on Earth, rather than being a purely harmful process.

- 14th May 2013What is an antigen?
- 15th May 2013State why a reflex action is described as involuntary.
- 16th May 2013A student counts 3, 5, 4 and 8 dandelion plants in four separate 1 m^2 quadrats. Calculate the mean number of dandelions per quadrat.
