• RED SLIDE: These are notes that are very
important and should be recorded in your
science journal.

-Nice neat notes that are legible and use
indentations when appropriate.
-Example of indent.
-Skip a line between topics
-Don’t skip pages
-Make visuals clear and well drawn. Please label.
Kidneys
Ureters
Urinary Bladder

• RED SLIDE: These are notes that are very
important and should be recorded in your
science journal.
• BLACK SLIDE: Pay attention, follow
directions, complete projects as described
and answer required questions neatly.

• Keep an eye out for “The-Owl” and raise
your hand as soon as you see him.
– He will be hiding somewhere in the slideshow
“Hoot, Hoot”
“Good Luck!”

 New Area of Focus: The Muscular System.

• Movement is carried out by the muscular
and skeletal system working together.

• Muscles turn chemical energy into kinetic
energy or the energy of motion.

“I eat mice to give me the
chemical energy so I can
flap my wings (kinetic).”

chemical energy to flap my
wings (kinetic).”

• How many muscles are in the human
body?
– A.) 650,000,000
– B.) 6,500
– C.) 650
– D.) 65
– E.) 6.5
– F.) Nobody Knows.

• Blood vessels are also woven into the
muscles to…

• Upon stimulation by an action potential
(Your Brain and nerves), skeletal muscles
perform a coordinated contraction by
shortening.

• Muscle can also be voluntary and
involuntary.

involuntary.
– Voluntary muscles you can control.

involuntary.
“I love you.”

involuntary.
– Involuntary muscles are ones that you can’t
control.

• Which is voluntary and which involuntary?
A B

A = Voluntary B

A = Voluntary B Involuntary

A = Voluntary B Involuntary
Kind of, you can
control it, but it
also works on its
own.

 Muscle Fiber: Long fibers that run parallel
to each other and are held together by
connective tissue.

 They contract

connective tissue.
 They contract and relax.

• Activity! How muscles work?
– Interlock your fingers with your palms toward
you. (Actin, Myosin)

• Activity! How muscles work?
– Push the fingers together so that the overall
length from one thumb to the other is
decreased (sarcomere length decreases).

• Individual muscles can act only to shorten,
and not to lengthen the distance between
two attachment points. (Tendons)

• Individual muscles can act only to shorten,
and not to lengthen the distance between
two attachment points. (Tendons)
– They can only pull, they can’t push.

• An example would be the contraction of the
biceps and a relaxation of the triceps.

• Smooth muscles work by sending a signal
in a wave over several cells

• Smooth muscles work by sending a signal
in a wave over several cells
– This wavelike action helps in moving food
through the intestine.

• Activity! Move the golfball (food) through
the intestine (long bag) with your fist in a
wave motion.
-Have some table
members hold rulers,
-One or two members
work together to wave
the ball through entire
intestine using only a
fist.
-Some water and dish
soap will make the
process easier.

• Video Link! (Optional) Muscular System
• 7 minutes
– https://www.youtube.com/watch?v=C6u0u_59UDc

• Activity Sheet! Please fill in the correct name
for some common muscles on the human
body. Use the website below to help you.
– Common names for muscles will work.
• Example – Pectoralis Major can become Pectorals.
– http://www.gwc.maricopa.edu/class/bio201/muscl

Please add some of the more
common names to your sheet.

This is on the quiz.

“Oh-no!”
“We have to do it again.”
“But without our sheet.”

• Review Opportunity before doing it again.

– Music for quiz
• http://www.youtube.com/watch?v=QEjgPh4SEmU

“Did you know
that your tongue
is a group of
muscles.”

• Bonus: Which Rocky Movie is this?
– Do you know the name of the Russian?

• Chicken Leg Dissection Available Sheet

• Lab Activity! Chicken Dinner.

• Lab Activity! Chicken Dinner.
– Caution! This lab will deal with raw meat.
Pathogens can be present.
– Do not put hands in mouth / rub eyes.
– Clean all surfaces thoroughly
– Watch out for cross contamination (Pencil
lands in raw meat and then you put
contaminated pencil in your mouth).
– Use refrigeration prior, and if lab carries over
another day.
– Dispose of meat properly at conclusion.
– Wash hands after clean-up.

Wear gloves and protective eyewear
during this lab.

during this lab.
Gloves to help you stay germ free,
and eyewear to prevent serious injury
as sharp objects will be used.

Use common sense. Safety First,
Last, and Always.

• Picture of best tool to use in this lab.

• We need you to perform this dissection
like surgeons.

• We need you to perform this dissection

in the results table.
– Make at least one observation of the skin.
• 2) Look at the hip bone / move it.
– What type of joint is it?
• 3) Gently move the knee joint?
– What type of joint is it? Can it move sideways?

• Step 3
• 1) Skillfully pull / cut to remove the skin using your
dissection tools.
– Is fat tissue present? Describe it in your journal
• 2) Look for fascia (shiny lining over muscles)
• 3) Examine the Muscle Tissue and record your
finding in the results table.

• Step 4
• 1) Separate the muscles into bundles
using your fingers until you have a small
pile of muscle bundles.
• 2) Look for tendons at the end of the
muscle bundles or still attached to the
bone.
– Record results in data table.

• Step 5
• 1) Look for arteries (blood vessels), and
thin nerves around the muscle and
tendons.
• 2) Carefully cut the tendons away near the
joint and look for ligaments.
– Record findings about the ligament in the data
table.
• 3) Identify the Femur, Tibia, and Fibula to
your teachers.

• Step 6
• 1) Skillfully remove excess material to
expose the joint A (knee).
– Don’t cut the ligaments / cartilage
• 2) Move this joint around and observe the
“Hinge”
– Make a sketch of this joint in your journal
• 3) Record properties of cartilage (Tissue
that lets joints slide easily and absorbs
shock) between joints on your data table.

• Step 7
expose the joint B (Hip).
“Ball and Socket”
– Make a sketch of this joint in your journal

• Step 7
expose the joint B (Hip).
“Ball and Socket”
– Make a sketch of this joint in your journal.

• Step 8
• 1) Skillfully cut the ligaments around each
joint and remove the bones.
– Complete the bone section of the data table.
• 2) Draw a sketch of the ends of each bone
and how they fit together.
• 3) Using your hands, break the Tibia in
half and make a sketch of the bone
marrow.
– Red =Place where blood cells are made.
– Yellow = Fats are made.

• Step 9
• 1) Dispose of all parts of chicken leg to
disposal area (trash bag).
• 2) Carefully bring all tools to clean up area
and clean properly.
• 3) Disinfect area properly.
• 4) Remove eyewear and gloves with
teacher approval and dispose of gloves
properly. –Watch for contamination!

• Activity for digestive system!
– Place small piece of chicken meat and bone
into a jar with vinegar.
– Take a similar size of meat and cut with a knife
into many pieces and place in another jaw
(simulated chewing)
– Add vinegar and cap jar and set aside until you
reach the digestion system / digestive juices.
