August 2009 - GCSE Science 5-a-day
Every GCSE Science sheet published in August 2009, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in August 2009
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st August 2009State two factors that increase a driver's thinking distance.
- 2nd August 2009Name a typical material used to make a permanent magnet, and a typical material used to make an induced (temporary) magnet.

- 6th August 2009A yeast culture respires without oxygen. Name the two products of this reaction, and name one industrial process that relies on it.
- 7th August 2009A man who is a known carrier of cystic fibrosis (Ff) has children with a woman who has been confirmed to carry no cystic fibrosis allele at all (FF). Explain why none of their children can have cystic fibrosis.

- 11th August 2009Concentrated sodium chloride solution (brine) is electrolysed using inert electrodes. State the products formed at the cathode and at the anode.
- 12th August 2009Explain why increasing temperature increases the rate of a reaction, referring to both the frequency and the energy of collisions.
- 13th August 2009State the difference between a pure substance and a formulation.
