Intermediate 2 Biology are studying Natural Selection. Organisms best adapted to the environment survive and go on to produce offspring. So what colour of worm would be most suitable for survival? S3 are investigating this by placing out different coloured worms and looking to see which ones will "survive". To make it a "fair test" they have to make sure that their worms are all the same length so here they are cutting the green coloured "worms" equally to 4cm.
