Bones
Definition
• the hard connective tissue forming the
substance of the skeleton of most vertebrates,
composed of a collagen-rich organic matrix
impregnated with calcium, phosphate, and other
minerals.
• Review: Tendons are tough inelastic bands that
hold attach muscle to bone. Tendons allow your
muscles to move your bones!
Purpose of Bones in the Body
• The main job of the skeleton is to provide
support for our body. Without your
skeleton your body would collapse into a
heap. Your skeleton is strong but light.
Without bones you'd be just a puddle of
skin and guts on the floor.
Purpose Cont…
• Your skeleton also helps protect your
internal organs and fragile body tissues
• The brain, eyes, heart, lungs and spinal
cord are all protected by your skeleton.
• Your cranium (skull) protects your brain
and eyes, the ribs protect your heart and
lungs and your vertebrae (spine,
backbones) protect your spinal cord.

Breaking Bones
• Bones are tough and usually don't break
even when we have some pretty bad falls.
• Bones will bend a little, but if you fall the wrong
way from some playground equipment or maybe
your bike or skateboard you can break a bone.
• Doctors call a broken bone a fracture.
Healing
• Bones are made of living cells.
• When a bone is broken your bone will
produce lots of new cells to rebuild the bone.
• These cells cover both ends of the broken
part of the bone and close up the break.
How do you keep your bones
healthy?
• Bones need regular exercise to stay as strong
as possible. Walking, jogging, running and other
physical activities are important in keeping your
bones strong and healthy.
• Riding your bike, basketball, soccer, gymnastics,
baseball, dancing, skateboarding and other
activities are all good for your bones.
• Make sure you wear or use the proper
equipment like a helmet, kneepads, shin guards,
mats, knee pads, etc... to keep those bones
safe.
Strengthening your Bones
• Strengthen your skeleton by drinking milk
and eating other dairy products (like low-
fat cheese, frozen yogurt, and ice cream).
They all contain calcium, which helps
bones harden and become strong.
Activity 1: Labeling the Bones
Activity
• Get into Groups of 3 or 4
• Gather 1 roll of tape & small sheets of paper
• In your group you will need 1 model, and 2 or 3
labelers
• You are to label each bone on the body on your
model
• When you are done raise your hand so the
teacher can check the model
• Remember: DO NOT touch any model in their private
parts, if you do you will be sent to the office, given a
referral, and ALL of your points will be lost for the day
Activity 2 – Tape Skeleton
• Get into groups of 3
• Materials: 1 big sheet of paper, 1 roll of
tape, 1 pen/pencil
• Your group is to create a skeleton out of
tape and tape it on the sheet of paper.
• You are to label each individual bone.
Activity 3: Bones Song
• Get into groups of 3 or 4
• Your group is to create a song or rap
about the bones
• This activity is to help you remember the
names of the bones and where they are
on your body.
• At least one member of your group will
have to perform the song for the class.
