- SKELETAL SYSTEM: THE BONES IN YOUR BODY: WHAT DO THEY DO? 2 nd
Grade
- Slide 2
- Subject: Bones of the human body Educational Objectives: For
every student to understand the basic bones in the body Learn what
they bones do The importance of them and certain bones Be able to
identify bones
- Slide 3
- DIRECTIONS Click, read and learn! Look and study the slides,
the information, and the pictures. Learn about everything the bones
do and why we have them. Be ready to answer questions! Do not worry
if you get them wrong. Part of learning is making mistakes. So just
go back and try again. Click on the screen and read. When you see
an arrow, like the one in this corner, Click it, you are ready to
go to the next slide.
- Slide 4
- THINGS TO KNOW: THE BASICS What are bones? Bones are what
shapes our bodies. They are everywhere in your body. Squeeze your
finger. Feel something hard? That is one of many of your bones. In
your hand you can even see your bones moving. Just wiggle your
fingers and look at the top on your hand. See the bones moving?
What is the Skeletal System? It includes all the bones, from your
head to your toes, in your body. The skeletal system plays a very
important part of your whole body. Go back to the Question
- Slide 5
- THE TRUTH ABOUT BONES YYou have 206 bones in you TThe largest
bone is the femur TThe thing bone or your upper leg TThe smallest
bone is inside your ear TThey are alive! Go back to the
Question
- Slide 6
- WHY DO WE HAVE BONES? PProtection TThe bones keep everything
safe inside of you like your lungs, heart and brain. SSupport TTo
shape the body WWhat if we didnt have bones? We would look like a
puddle MMovement LLets you move around. TThink how often you move
around while sitting, walking, playing. Your bones let you do that!
Go back to the question We have bones for 3 main reasons
- Slide 7
- WHAT ARE BONES MADE UP OF? They are not just hard things inside
your body They have a hard outside and a spongy inside There are
lots of material in your bones, one of the most important ones is
bone marrow
- Slide 8
- WHY BONE MARROW IS IMPORTANT The Bone marrow at the center of
the bone and makes blood cells for the body Blood vessels run
through the center of the bone so that the bone receives food,
oxygen and minerals (minerals keep you healthy!) It makes red blood
cells (needed to transport oxygen throughout the body) These red
blood cells supply oxygen to our soft tissues, and white blood
cells to fight germs or disease. They also gives us energy by
storing and releases fat.
- Slide 9
- THE SPINE Your spine is one part of the skeleton that's easy to
check out: Reach around to the center of your back and you'll feel
its bumps under your fingers. That is your spine! The spine lets
you twist and bend, and it holds your body upright. It also
protects the spinal cord, a large bundle of nerves that sends
information from your brain to the rest of your body. The spine is
special because it isn't made of one or even two bones: It's made
of 26 bones in all! These bones are called vertebrae (say:
ver-tuh-bray) Every bone is important in your body but there are
some that play a very important part in keeping you alive like the
spine, ribs and skull
- Slide 10
- THE SKULL Knock on your head. Feel hard? Touch beneath your
eyes, you can feel the ridge of the bone that forms the hole where
your eye sits. That is part of your skull. All the bones in your
head/ face are called the skull The skull protects the most
important part of your body, your brain! The skull is actually made
up of different bones. Some of these bones protect your brain,
whereas others make up the structure of your face. Go back to the
Question
- Slide 11
- THE RIBS Run your fingers along the side of your body. Feel the
bumps? Those are your ribs! Your ribs act like a cage around your
chest. Because of this cage, they keep your lungs, heart and liver
safe Your ribs come in pairs, and the left and right sides of each
pair are exactly the same You have 12 pairs of ribs
- Slide 12
- HOW DO BONES MAKE YOU MOVE Fixed JointsMoving Joints Joints
that are stay in place and do not move at all are called fixed
joints Along the side of your skull you have fixed joints Joints
that move are called moving joints. These joints are the ones that
let you climb a tree, eat food, and play board games. There are two
types of moving joints Hinge joint these joints let you bend and
straighten like your elbows and knees Ball and socket joint- one
bone is shaped like a door knob and it meets at the other bone that
has a hole that fits. These joints are located at your shoulders
and hips. They let you do some serious moving in almost every
direction like for swinging a baseball bat, dancing and running.
The place where two bones meet is called a joint Some joints move
and some do not. Click on the cameras to see a picture
- Slide 13
- KEEPING YOUR BONES HEALTHY Protect those skull bones (and your
brain inside!) by wearing a helmet for bike riding and other
sports. Eat healthy foods that include a lot of calcium, which
helps bones harden and become strong. Food like yogurt, milk,
salmon, and even broccoli have calcium Stay active!! It is good for
every part of your body to stay active, exercise, and play.
- Slide 14
- FIXED JOINTS The place where two bones meet is called a joint
Fixed Joints Fixed joints to do not move. The lines on the skull
are fixed joints Click here to return to slide
- Slide 15
- MOVING JOINTS The place where two bones meet is called a joint
Joints that move are called moving joints. All the red circle are
moving joints Hinge joint these joints let you bend and straighten
like your elbows and knees Ball and socket joint- They are made up
of the round end of one bone fitting into a small cup like area of
another bone

- THINK: QUESTION 1 What do think the human skeletal system looks
like? Click the picture
- Slide 17
- TRY AGAIN Try to imagine what you would look like without skin
or what is under your skin Click on the question mark to go back to
slide to help you answer the question.
- Slide 18
- CORRECT! Good imagination. That is what the skeletal system
looks like! Click the smiley face to continue
- Slide 19
- QUESTION 2 You have read a lot about bones so far, lets see if
you remember it. Read and then answer the question What is the
largest bone in your body called? Femur(thigh) Funny bone Inside
your ear The hand

fill in the blanks. Click on the space to see answer. Then click
finish when you are done. Finish!! skull Ribs spine Hinge joint
Ball and socket joint
- Slide 28
- FANTASTIC JOB! YOU HAVE REACHED THE END Hopefully, you have
learn about the human skeletal system and why we need one to live.
The reason why we have bones and why they are the key to keep our
organs and bodies safe. There is much more to learn about bones, if
