4. Hungry Alligator Teacher Notes
Contemplate
Set up enough space for books, paper, scissors and other materials and for demonstrating your
model.
Gather some books or search internet sources for information about other sources of food for
alligators. Choose a type of food. Then draw it and cut it out or make it. Prepare an information
sheet, digital slides, or notes for your demonstration.
You are demonstrating alligator behavior: the motion sensor feedback allows the alligator model
to react to the food. You may wish to adjust the input numbers to the Play Sound and to the Motor
On For timing to suit your demonstration better.
Practice presenting your information about alligators and timing the demonstration.
After the alligator presentations, discuss these ideas.
How is the alligator program like a real alligator's brain?
The program is like a brain because it makes decisions and causes movement to respond to the
environment.
How is the alligator program different from a real alligator brain?
A real alligator brain is capable of more sophisticated and varied responses. It is 'programmed'
to respond to much more than a simple showing of food.
Is this an alligator or crocodile?
It is more like an alligator because they have U-shaped jaws. Crocodiles have more pointed and
narrow jaws.
Alternative ideas...
Describe a day in the life of your alligator by drawing a series of pictures. When is the alligator
awake? When is it eating?
