Introducing the project: Producing a TV show about how an animal uses its senses.

Planning Get into groups(6-8). Decide which animal to focus on. Clear assignments.

The animal’s name Decide what type of show : It’s unique sense Decide what type of show : A documentary, a drama, a cartoon, other show

Clear assignments Each member picks a different topic to find information about Food( what the animal eats) Habitat(where the animal lives) Size(size of the animal or population) Myths about this animal(what people think)

Preparing Visit a zoo , watch an animal documentary,look at books, surf the Internet……to find information about the animal. What it eats and how it finds food in the wild How it protects itself How it communicates with other animals How it attacks people or other animals (if it does) How it helps people or other animals (if it does)

Producing 1. Focus your research on how your animal uses its senses. 2. TV is very visual so pictures should be presented in an easy to see way. 3. Each member must work on different part of the show, keeping in mind the overall design. 4. Each member has to proofread the writin at least once, correct mistakes if there are any, and add any new ideas they can think of.

Presenting Present your show to the class. Put you display on the display wall.

Homework Do Parts partA, B and C on page 90 in Workbook. Review words and phrases in this unit.

Blue shark

The shark has senses specially adapted for the animal's life underwater. Smell is a shark's most acute sense. Approximately 70 percent of the shark's brain is used for olfactory (smelling)  functions. Experiments have shown that sharks can detect prey solely by smell, and the hungrier the shark, the less stimulant needed to elicit a reaction.

Sharks are sensitive to light and can detect certain objects even in murky water. Some have a tapetum lucidum, a mirror like layer under the retina of the eye that reflects incoming light and increases the amount of light available to the eye. (Cats and other animals whose eyes "glow in the dark" also have this feature.)

Sharks do have ears, but the role of hearing in the shark's location of prey is not well understood. A shark can detect sound waves and disturbances in the water with its lateral line, or lateralis, system. This is a series of thin canals, filled with water, that runs along the animal's side. The canals are attached to nerves that send signals to the shark's brain.

Sharks can also sense electric and magnetic fields Sharks can also sense electric and magnetic fields. Sensory pores located on the shark's head can detect a prey's bioelectric field even if the prey is buried in sand. A shark can also detect the Earth's magnetic field. Open-ocean sharks may use this information to navigate and orient themselves.
