5. Research and prepare a 4-minute talk about how animals communicate information with each other. This should be a general talk with lots of examples rather than an in-depth talk on one aspect. We will then hear each others talks.

6. IL Find out more about particular types of communication, for example threat displays to fend off predators or competing males, territorial scent marking, singing or other displays to attract mates. Produce a presentation or poster which we can look at next lesson.

7. Plenary Compile a list of the benefits and disadvantages of chemical communication, compared with visual or auditory communication.

8. Plenary Advantages could include: the fact that chemicals do not depend on lighting conditions (as visual signals do), they may be sensed over great distances and around corners, and they last longer (e.g. a scent trail can last for days). Disadvantages are: that they only spread downwind, the information content is often lower than with sound or visual, and chemicals in scent trails can be washed away by rain.
