What things do all animals have in common?
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.
What are some ways animals differ?

Behaviors Definition or
explanation Examples
1. Survival
2. Innate
3. Learned
4. Seasonal
5. Rhythms
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.

Learned?
