class discussion?
Okay let’s have
an active class
discussion!

questions
Pouring Water Demonstration
Planet 1
Planet 2
Planet 3
Planet 4
What will happen when you fill a cup
with water and then turn it over?
Should we be
exploring other
planets in
search of life?
In what ways have we been able to
explore other planets/moons?
Comparing current methods of
exploration:
Satellite/Probe
Pros
Cons
Mobile Robot
Manned Mission
What would be the best way to
explore other planets/moon?
Journal Question:
What can you learn
from dissecting a
fetal pig? Do you
think it is worth it?
Explain.
To truly explore other planets, we
need to be able to interact without
barriers.

2. Watch movie
and answer
questions.
3. Have fun!
JQ: Would you choose to be

JQ: Is an Avatar living or
non-living?
How do you construct an Avatar?
“Good science is good observation!”
What does that mean?
Quick Dissection Activity and Data
Collection
In order to
understand how we
will survive space
exploration, we
must understand
how our bodies are
“put together”
To review organ systems thru dissection video:

How can I remember all eleven organ systems?
C DR SMILE RUN
Cardiovascular
Digestive Respiratory
Skeletal Muscular Integumentary Lymphatic Endocrine
Reproductive Urinary Nervous
Circulatory System
Function –
transports
substances
throughout the
body using heart
Organs – heart,
arteries/veins &
blood
Digestive System
Function – breaks
down food into
usable substances &
absorption through
intestines
Organ – esophagus,
stomach, and
intestines
Respiratory System
Function – moves
air in and out of
lungs
Organ – trachea,
pharynx, bronchi
and lungs
(diaphragm
helps)
Skeletal System
Function – provides
support and structure
to the body, site for
blood production (red
and white cells),
Organ – Bones
Muscular System
Function – allows
your body to move
through contraction
and relaxation
Organs– muscles
Integumentary System
Function – serves as
a barrier & protects
against infection (1st
line of defense)
Organ – skin, nails,
hair follicles,
sweat glands
Lymphatic System
Function – defend
against pathogen
and disease with
white blood cells
(2nd line of defense)
Organs –lymph
nodes/lymph
vessels
Endocrine System
Function – slowly
relays messages
that regulate
the body
(growth and
development)
Organs –
glands
Reproductive System
Function –
production of
sperm & egg cells
to create
offspring.
Organs – testes &
penis; ovaries,
fallopian tubes,
uterus.
Urinary System
Function –
filters &
eliminates
waste from
the blood
Organ –
kidneys,
bladder
Nervous System
Function – quickly relays
messages to and from
brain through cells called
neurons that regulate
behavior.
Organs – brain, spinal
cord, sense organs
Journal Question: How can you
learn about yourself by
dissecting the fetal pig?
Explain.
What are all organ systems
working toward?
Homeostasis – process by
which organisms keep
internal conditions
relatively constant
despite changes in the
external environment.
Examples: temperature, heart
rate, blood pressure, etc.
Objectives:
-Use technology appropriately in school
-Visualize the 11 organ systems
- Recognize that by studying the fetal
pig you can understand how a human
and is constructed.
-Visualize and interconnectedness
between organs and organ systems.
-Develop basic dissecting skills.

your desk.
Your homework
tonight is to
complete the
Dissection Lab
Internal Dissection
1.

expose internal organs.
3. Identify all internal
organs and show
teacher.
4. When finished, work on
Post-lab questions.

2. Digestive System
3. Urinary System
Going Further:
Remove the Brain
The organ system and brain
must be intact in order to
receive full credit for it.

in the bag provided
and bring up front.

clean tools and tray,
return to cart.

JQ: Did the fetal
pig dissection meet
your expectations?
Elaborate.
Take out your lab.
You need your
textbook tomorrow.
1. Fontanelles are the
“soft spots” on a young
human, or pig’s skull.
What would be the
benefit of having spaces
between the sections of
the skull? Explain.
2. Humans, like the pig,
have cartilidge rings
holding their trachea
(windpipe) open. Why do
they need these rings?
1. When most
organs/tissues swell, they
grow bigger until the
damage is fixed. What
restricts the brain from
swelling, and what could
happen if the brain swells
too much?
2. In many mammals, the
lungs are late to develop.
Why would they develop
later than many other
organs?
Fetal Pig Dissection Write-up
1. What was the purpose
of the fetal pig
dissection?
2. Compare and contrast
the organs/organ
systems of the fetal
pig and the avatar.
3. Why are the anatomy
and physiology
different between the
fetal pig and the
avatar? Explain
JQ: What do you
see?
Welcome to
Name that Image!
How are these

that magnifies
images that are
too small to be
seen with the
naked eye.
