November 2014 - GCSE Science 5-a-day
Every GCSE Science sheet published in November 2014, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in November 2014
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st November 2014What observation showed the nucleus is positively charged and very small?
- 2nd November 2014A force of 40 N is applied 0.25 m from a pivot. Calculate the moment.
- 3rd November 2014A rectangular coil carrying a current is placed in a magnetic field, with its two long sides parallel to each other. Explain why the coil rotates rather than moving in a straight line.
- 4th November 2014A student measures 24 cubic centimetres of gas in 3 minutes. Calculate the rate.

- 6th November 2014Give one way of reducing the spread of malaria.
- 7th November 2014Define homeostasis.
- 8th November 2014Give one example of variation that is caused purely by the environment rather than by genes.
- 9th November 2014A sample contains 90% of an isotope with mass number 10 and 10% of an isotope with mass number 11. Calculate the relative atomic mass, to 1 decimal place.
- 10th November 2014Why do elements in the same group have similar chemical properties?

- 21st November 2014Give one risk of stem cell treatment.
- 22nd November 2014Why does a potometer measure water uptake rather than transpiration directly?
