Directions:Match the bone vocabulary with

the bones on the human skeleton.Record the terms

one the mini skeleton

worksheet.

1. What is the skeletal system made of?

Bone

Cartilage (spongy tissue between bones and joints)

Muscle (that attach themselves and allow us to move many different ways)

2. How many bones are there is the human skeleton?

206

3. What are the largest and smallest bones in our body?

• Largest “Femur”

• AKA thigh bone

• Usually grows to about 2 feet long

• Smallest “Stirrup”

• Located in your ear and looks like a stirrup on a saddle used for horseback riding

HINT

4. What are the 3 main functions of the skeletal system?

Provides structure, enables you to stand up

Protects delicate organs and tissue (e.g. your skull protect your brain, your ribcage acts like armour for your and

Muscles attach themselves to bone, allows you to move

HINT

5. Why is it necessary for our survival?

• Without bones, you would just be a puddle of skin and guts on the floor

6. How do our bones grow?

• They fuse or grow together to form larger bones

7. How does a baby’s skeletal system compare

to a full grown adult’s skeletal system?

• Babies are made mostly of cartilage. The cartilage grows and thickens. Over time, its replaced by bones.

• Babies are born with over 300 bones

• A full grown adult has only 206 bones

• Why? The cartilage and bone fused together over time as the baby grows to be an adult

Bone

Cartilage

Cartilage is spongy tissue often located

between joints to

prevent them from rubbing together. We

also have cartilage in

our nose and ears.

8. Can we do anything to help our bones grow better and stronger?

• Drink milk, eat lots of low-fat dairy products

• This provides lots of calcium

• Be active. Exercise!

9. What are the different ways bones can be injured?

• Complete fracture: bone is in 2 pieces

• Greenstick fracture: crack on one side, not all the way through

• Single fracture: broke in one place

• Communicated fracture: in more than 2 pieces or is crushed

• Bowling fracture: bends but does not break. Most common in kids

• Open fracture: sticking through the skin

Both animals and humans can break bones …

10. How does a doctor diagnose types of breaks?

• The doctor has the technician take an x-ray so they can see the damage beneath the skin and determine what type of break/fracture occurred.

Carefully examine these xrays. Can you determine which bone has been

broken or fractured?

Oh my! What have we here?!

What about here?!

11. How are a break and a fracture different?

The mean the SAME thing!

Break = Fracture

Fracture = BreakI will need two brave volunteers…

12. How should a break/fracture be treated so it heals properly?

• Step 1: determine the type of break• Step 2: set it (re-break, surgery, pins etc.)• Step 3: wrap it in a special bandage• Step 4: cast is required

13. What is the difference between a vertebrate and an invertebrate?

A Few Examples

What would you classify a

Sea Cucumber

as?

Let’s Infer …The Sea Cucumber

• I know a Sea Cucumber lives in the sea

• It’s long and narrow like a cucumber or a balloon

• The Bill Nye video that we the saw yesterday said many invertebrates live in water because they can move despite not having a backbone

• They used a balloon to demonstrate how an invertebrate moves

Skeletal Comparison Project

* You may work with a partner. Use the required format. Must include minimal of 3 examples for each criteria.

Step 1:Choose 2 animals and compare their skeletons. Find an image of both, copy and paste them onto your chart. Make sure they are small enough to fit your chart.

Step 2:Using the chart provided, list POINT FORM how they are similar and how they are different from each other and from the human skeletal system?

* Remember, our focus is the skeletal system NOTwhere they live, what they eat, fur or no fur, etc.
