in this radio program howard stableford discovers how jurassic plankton ends up in our petrol tanks, why oil dominates world politics and what we might do when it starts to run out. its worth getting pupils to listen to the first 10 minutes or so of the program (including the bit about using a mars bar to illustrate the formation of sedimentary basins!), then get them to, for example, produce a timeline or cartoon strip to illustrate how plankton is converted to oil.
