  2. Learning objectives: • By the end of the lesson you should be able to: • Describe behavioural adaptations in animals using woodlice as an example.

  3. Introduction • Woodlice are invertebrates which are found under stones and decaying wood. • When woodlice are in these damp and dark conditions they _____________which increases the likelihood of __________________ ____________ Move slowly Remaining in the preferred conditions • The behaviour of woodlice in light and dark conditions can be investigated using a __________________________ Remaining in preferred conditions

  4. Aim • To investigate the conditions which woodlice prefer

  5. Method Light source • Set up the choice chamber as shown in the diagram 2. Add ten/twenty woodlice through the hole in the lid and count the number of woodlice in the uncovered part of the chamber after five minutes Moist filter paper Black paper Hole in lid

  6. Results

  7. Analysis • Draw a bar graph of the results Number of woodlice Light Dark Conditions

  8. Conclusion • Which conditions do woodlice prefer? • Woodlice prefer dark conditions

  9. Evaluation • Why were many woodlice used in the experiment? • To make the results more reliable
