In this activity, students investigate whether there is any evidence that earthworms can respond to vibrations in the ground.
By the end of this activity, students should be able to:
- justify their opinion about a strategy for catching worms and provide evidence for this opinion
- state the evidence that has been collected and analysed to substantiate their position
- link vibration production to worm numbers and worm behaviour.

Often scientists make observations and hypothesise an explanation. Hypotheses can be tested by other scientists as they build up evidence to refute or provide evidence for a hypothesis.
