Interest Approach

Pick out one or several students in the class who has a pet and ask them the following questions
to begin a discussion about the intelligence of animals. How smart is your dog? How do you
know he’s that smart / dumb? What type of actions make you think that he can think and
understand at some level? After some discussion, share the following information with the class.

Rena Durr, a psychology professor at Christian Brothers University in Memphis, subscribes to the
notion that animal intelligence is essentially a problem-solving issue. Instinctual behaviors never
change, whether or not they are appropriate. "If animals relied solely on instinct, we would not see
the individual variations in behavior within species -- for example, the observation that some cats
rescue their babies from burning buildings, while others kill and eat their babies," Durr said. She
noted that octopuses were added to the list of animals that require ethical treatment in labs after one
was seen reaching out of his tank and pulling a string to turn off a light bulb above.
He preferred the dark, like the bottom of the ocean."

For years, people have been speculating and hypothesizing about the levels of intelligence that
animals have. Today, we’re going to take the knowledge that we gained from Unit 3, Lesson 7, The
Nervous System, and apply it to the animal’s world to compare and contrast animal and human
nervous systems. The things we learn will lead us into our study of animal behavior.

Summary of Content and Teaching Strategies
Objective 1. Develop further understanding about the human brain by comparing and
             contrasting it with animal brains.

        Use the Animal Nervous Systems Powerpoint presentation and attached worksheet to
        review part 1 of the lesson and compare and contrast.

        On the worksheet I’ve given you today, I’d like you to take five minutes and write 5-7
        sentences answering the question at the top of your page. Can animals think? There is no
        right or wrong answer right now, but I want you to support your opinion with some
        examples from your life. There’s no need to talk right now, and I’ll turn on some music for
        you to enjoy while you write. Don’t worry if you see me looking over your shoulder – I’m
        just curious about your opinion. OK, impress me with your opinion! (Turn music on and
Unit 7, Lesson 1: The Nervous System’s Role in Animal Behavior                                            2
       walk around room to get an idea of where the students stand on this topic. Afterwards,
       ask a few students to share their answers.)
       Using the worksheet as a guide for note taking, go though slides 1-8 with students.

Objective 2. Define and understand terms dealing with the study of animal behavior.

       Use slide number 9 to introduce ethology, or the study of animal behavior. Then
       students will alternate taking notes on the slide and completing a short activity for slides

       Slide 10 – Read definition and take notes.
       There are two ways to illustrate reflexes. The Startle Reflex is best illustrated when I do this
       . . . (pop a balloon with a pin.) Most of you jumped. Why? To illustrate the second way,
       you need to get up and press your arm against a wall for 1 minute, then step away and relax.
        After doing this, the arm should raise. Why does this happen? Do you have to consciously
       think about it for it to happen?

       Slide 11 – Read definition and take notes.
       In the margin of your paper, write this sentence: Agriculture is an important part of society.
        Now, take a look at your sentence. Did you all dot your i’s and cross your t’s? How did
       you know to do that even though I didn’t tell you too? It’s a habit you formed years ago in
       elementary school when you learned to write.

       An important part of habituation is trial and error. When I say go, find yourself a partner
       quickly and I’ll bring you a maze for one person to complete while the other times him or
       her. (After completed, hand out another copy of the same maze and give them the same
       instructions. After the third time, compare the times and you should see a decrease with
       trial and error.)

       Slide 12 – Read definition and take notes.
       Try your reasoning skills on these:
       Although each of the following sentences sounds okay at first, there's really something
       wrong with each one of them. Read the sentences and explain why each one is a little "fishy."
       1.     No one goes to that restaurant any more because it's too crowded.
       2.     I'm glad I don't like spinach, because if I liked it, I'd eat it, and it tastes awful.
       3.     If you can't read this sign, ask for help.
       1.     If no one goes to the restaurant, it can't be crowded.
       2.     If the person did like spinach, he or she wouldn't think it tasted awful.
       3.     If the person can't read the sign, she or he won't know that it says to ask for help.

       Here’s another: A man named George was hurrying to get ready for a dinner party when
       Dan rang his doorbell. "I'm just rushing off to a dinner party," said George, "but I'm sure it

Unit 7, Lesson 1: The Nervous System’s Role in Animal Behavior                                          3
       would be fine if you came along." So the two went off together. When they arrived at the
       party, George, who always enjoyed getting people to use their heads, introduced Dan to the
       other guests with the following rhyme: "Brothers and sisters have I none, but this man's
       father is my father's son."
       How were George and Dan related? (Dan was George’s son)
       These seem easy to you – but only because you know how to use your reasoning skills.
       Slide 13 – Read definition and take notes.

       Intelligence is often judged by using exercises to test short and long term memory or test
       your ability to recognize patterns. Try this one.

       What do the three words in each of the following groups have in common?
       (Example: What do the words "ram," "raven", and "bull" have in common? All three
       animals have given their names to sports teams.)
       1.     saddle, pump, slide
       2.     mustang, cougar, rabbit
       3.     department, shoe, book

       1.    Each word names a different kind of shoe.
       2.    Each word names an animal that has given its name to a kind of car.
       3.    Each word names a different kind of store.

       Make sure each of the terms we discussed today is captured on your worksheet because we’ll
       use them tomorrow to learn about the basic 10 types of animal behavior.

Objective 3. Describe the scientific work of Ivan Pavlov and its relation to behavior.

       Use slides 14-16 to teach students about the work of Ivan Pavlov and conditioning. The
       first two slides are informative. At the end of the second slide, follow the link to play a
       simple game on the internet that illustrates this concept. Then use the third slide to
       review. At the end of the three slides, ask students to use pictures instead of words to
       illustrate the concept on their worksheet.


       The last item on your worksheet asks you to re-evaluate your stance on the question “Can
       animals think?” The difference is this time; you must describe your opinion without using
       full sentences. Instead, you’ll use an outline format. I challenge you to include some of the
       terms we just learned.

       The last thing we need to review today is some of the vocabulary words we introduced. The
       better you learn them, the easier tomorrow’s work will be. You have about 5 minutes to
       spend with a partner, quizzing each other over the words on your worksheet. Go! (Turn on
       the music if you want.)

Extended classroom activity:
    The last slide of the PowerPoint presentation contains pictures of a bos indicus brain and
       zebra brain. Compare and contrast them with students while reviewing what was learned
       in Unit 3, Lesson 7: The Nervous System about the parts of the brain and their functions.
        This activity could include an outcome of writing / drawing / speaking / debating.

FFA activity:
    The topic of animal behavior is a controversial one that would be perfect for debates.
      Students can meet one degree qualification by leading a 10 minutes discussion with the
      class. This is also a good topic for prepared public speaking.

SAE activity:
   Students could complete an exploration SAE project by researching careers that deal
      with animal behavior (ranching, horse trainer, vet, etc.)

      Students should evaluate what they have mastered with the attached multiple choice quiz
      as well as a grade for their worksheet, complete with drawings, writings, etc.
