What are some examples of animals?

Finish and turn in outline 1.1

Begin the next outline (1.2 or 1.3)

Multicellular Many EUKARYOTIC cells with no cell walls Form tissues

Reproduce sexually Some can reproduce by “budding”

Develop from embryos Stages of development

Have specialized parts; organs

Move

Are heterotrophs/consumers

Choose any animal.

Use the 6 statements on the prior slides to EXPLAIN why it is an animal. You MAY NOT use the underlined words.

Ex: Monkeys can climb, …

VERTEBRATES – skull & backbone

less than 5% of all animals

INVERTEBRATES – no backbone •Most of the animal kingdom!

Analyzing Data… •Find the pie graph on page 5

•Answer these questions:

1. What group of animals has the most

species?

2. How many species of beetles are there on

Earth?

3. How does the number of beetles

compare with the number of mammals?

4. How many species of vertebrates are

known?

9 Groups… Porifera Cnidaria Platyhelminthes Nematoda Annelida Mollusca Arthropoda Echinodermata Chordata

Invertebrates

Vertebrates

Asymmetry: no symmetry; irregular

Radial: like a wheel;

Radiate from center

Bilateral: split down the middle;

2 identical sides

What are the 6 characteristics that make something an animal?

What group of animals is the largest?

What is the part labeled at A on the microscope pictured here? How much does part A magnify your slide?

How do you figure out total magnification of a slide?

With your group, put the slips of microscope directions in order from the first step to the last.

Behaviors Definition or

explanation Examples

1. Survival

2. Innate

3. Learned

In order to stay alive;

Find food, water, avoid

Being eaten; use little energy

Predator: eat animals

Prey: eaten by animals

Camouflage: blend in with

Background

Coloration: bright, etc. to

warn

Doesn’t depend upon

learning or experience;

Influenced by genetics

Communication;

acquire language

Modified by watching or

experiencing

Language (German

English, Spanish, etc.)

Behaviors Definition or

explanation Examples

4. Seasonal

5. Rhythms

Things done in

response to the

season

Hibernation: period of

inactivity; lower body

temperature; winter

Estivation: slow

period; hottest part of

summer; reduced

activity

Internal clocks or calendars

Biological clocks: natural

cycles; clues from nature;

seasonal, hibernation,

migration, etc.

Circadian: around the

day; daily cycles; sleep,

eat, etc.

Behaviors Definition or

explanation Examples

6. Navigation

7. Social

How animals find their

way from place to place

Landmarks; mental

maps; smells, etc

Communication; territory;

pheromones; noise, body

language, touch; live in

groups

Interactions with others

of the same species

What characteristics make something an animal? Describe 1 type of symmetry.

Innate: controlled by

genetics

Learned: innate behavior

that is modified

NATURE VS NURTURE…

Critical Thinking & Reading • Read “Masters of Navigation”.

• Answer the following:

1. Is the migration of the Blue-winged Teal innate or

learned? Explain

2. Is the migration of the New Zealand Cuckoo innate or

learned? Explain.

3. For migration, birds use combinations of visual

clues, smell, the Earth’s magnetic field and the sun.

Which would be more useful in unfamiliar areas?

Explain.

To find the most food

using the least energy

Finding Food…

Blend in

Some change color or appearance

Camouflage…

Protection from predators

Chemicals

Herds

Defense…

Avoid animals with colors

and patterns associated

with pain, illness, etc

Stay away!!!

Warning Coloration…

Travel from one place to

another

Obtain food, water,

nesting

Migration…

Period of inactivity

Decreased body temp

In winter

Food is scarce

Hibernation…

Nonfiction Reading

• Read the article on bat hibernation

on page 24 of your textbook.

• Answer the questions on the activity

page Mrs. Lock gave you.

Period of reduced

activity

In summer

Estivation…

Internal control of

natural cycles

Use clues from

surroundings to set

“clock”

When to fly south

Biological Clock…

Daily cycles

When to go to bed

Circadian Rhythms…

Find way from one place to

another

Navigation…

Internal Clock Activity

• Find the Internal Clock activity

• Using a stopwatch, have 1 partner estimate the time of 60 seconds. Repeat the trial 2x.

• Estimate 60 seconds while taking pulse.

• Estimate 60 seconds while breathing.

• Switch partners.

• Answer the questions.

Between animals in the same species

Smell; pheromones

Sound

Body language

Touch

Communication…

Pros

Help spotting predators

Help finding/killing food

Cons

Attract predators

Compete for food

Transmit disease

Living in Groups…

Yawning Cycles

• For 1 day, keep track of the number of times

you yawn. Take note of what times and

what conditions are present when you

yawn.

• Graph your data on the activity sheet Mrs.

Lock gave you.

Animal Behavior Assignment

• Make a chart – Behavior / Definition/ Example / Innate or Learned

• List 5 of the 10 behaviors discussed today.

• Write a definition for each behavior.

• Then, give an example for each behavior.

• Finally, identify whether your example is innate or learned.

Behavior Definition Example Innate or

Learned?
