Facilitator Set-Up for Animal System Lab
Print off four copies of each station card in color per lab table.
Laminate each card or place in pocket protector. Provide pens at
each station.
Print off four copies of graphic organizer per station. To provide the
differentiation experience:
– Station 1 provide participants with only the graphic organizer and a
transparency pen.
– Station 2 provide participants with the graphic organizer and names of
systems (Do not include all systems)
– Station 3 provide participants with the graphic organizer and pictures of
systems (Do not include all systems)
– Station 4 provide participants with a body system overview sheet.
– Station 5 allow participants to choose from the four methods of
differentiation above.
Students will need a copy of the student sheet to fill in.

Opossums Play Dead
When opossums are startled or feel threatened they often play
dead which is also known as playing possum. This behavioral
response is known as thanatosis. To play dead, the opossums’
heart rate decreases, it lies on its side, and its body stiffens as
muscles contract. The possum drools and does not respond to
external stimuli. Many possums release feces or urine. Scientists
believe that this behavior is designed to deter predators including
wolves.

Pistol Shrimp Stuns Prey
The pistol shrimp has an adaptation that allows it to defend its
territory and stun or kill prey. The adaptation is a front claw that
functions like a water gun. When prey approach, the shrimp
contracts muscles which pull against the exoskeleton. The muscle
contraction results in the claw closing quickly. As a result, water is
displaced rapidly producing the a stream of water that stuns and
sometimes kills the prey. The closing of the claw also produces a
snapping sound that may startle predators.

Blood Shoots From Lizard’s Eye
Horned lizards have a defense mechanism that includes shooting
blood from their eyes. The major veins surrounding the eye of the
lizard are controlled by muscles. When the lizard contracts these
muscles, blood flow is increased to the head. As a result, a
specialized membrane similar to an eyelid fills with blood. Muscles
in the eyelid and eye contract to shoot blood when predators
approach. Scientists believe the blood deters predators.

Baby Koala Eats Feces
Baby koalas are mammals and begin their life drinking their
mother’s milk. The production of milk is controlled by a hormone
called prolactin. The young koala must transition from milk to the
eucalyptus leaf which is the primary diet of the koala. Surprisingly,
eucalyptus leaves are indigestible to young koalas. To prepare to
digest eucalyptus, juvenile koalas feed on pap. Pap is a specialized
form of feces produced by the mother. Pap allows the mother
koala to pass microorganisms which inhabit the intestine to her
offspring. As a result, the juvenile koala acquires the bacteria that
necessary to digest eucalyptus leaves.

Body System
Function
Nervous System
Senses stimuli; coordinates response to stimuli
Circulatory System
Transports gases, nutrients, waste, and hormones to and from the body cells.
Excretory System
Filters the blood to remove waste.
Digestive System
Breaks down food into smaller molecules that can be absorbed and distributed to cells.
Reproductive System
Produces eggs and sperm; develops and nurtures offspring.
Endocrine System
Produces hormones; regulates growth, metabolism, and development.

N. fowleri – Brain-Eating Amoeba
N. Fowler is an amoeba found in tap water, freshwater lakes,
pools, or streams. When a person comes into contact with water
containing these amoebas, the amoeba enters the body through
the nasal passage. The amoeba travels to the brain using the
olfactory nerves as a road. The amoebas’ use the brain as food. As
a result, the most common cause of death is hemorrhaging
(bleeding) in the brain and necrosis (death) of brain tissue. The
symptoms include headaches, fever, nausea and vomiting. As the
infection progresses it causes seizures, hallucinations, and altered
mental states. This infection is so severe that infected individuals
often die with in 1-2 weeks of infection.
