  1. B3.2 lesson 4 animal communication - Describe the different types of animal communication (Grade B) - Give examples of the different types (Grade A) - Explain how animal communication is beneficial (Grade A)

  2. COMMUNICATION What is it? How is it done? How can it help animals to survive?

  3. Types of Communication • Visual • Sound • Tactile • Chemical

  4. 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.

  5. 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.

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

  7. 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.
