Task 1: What understanding and misconceptions about food chains
and feeding relationships are revealed by these pupil-generated food chains?
Task 2: Below are some teacher questions and pupil responses
which reveal some misconceptions and incomplete understanding.
- Consider how you would appropriately respond to some of these answers.
Teacher question 1: What kinds of predators live in the woods around
- birds, insects and animals
- snakes, poisonous spiders and crocodiles
- venus fly traps
Teacher question 2: What’s happening here? (showing pupils the
following food chain:)
green plant ® rabbit ®
- it means that foxes eat rabbits and green plants
- after the fox eats the rabbit, we have to give it food or it will die
- there are loads of rabbits and quite a lot of foxes - but if all the rabbits
got killed, then we'd have to feed the foxes or they would all die too
Teacher question 3: What would happen to the other living
things if all the foxes died?
- the rabbits would be happy and more would grow
- the rabbits would grow bigger
Teacher question 4: Why are there more rabbits than foxes?
- so the foxes don't get hungry
- because there's lots of grass
- because someone feeds them
- because rabbits have lots of babies
Teacher question 5: How come the dead plants and animals in the woods disappear?
- they just disappear!
- birds and mice eat them
- they rot, then insects eat them
- people bury them
- they go into the soil and fertilise it, and keep making the soil deeper
