Copy of 3rd Grade Skeletal System
Transcript of Copy of 3rd Grade Skeletal System
Skeletal System What are Bones? The framework of bones which provides support, protection, and movement to the human body. Protect your internal organs from harm.
Support your body & give it shape.
Provide a frame for your muscles, allowing you to move.
Store minerals and make blood cells which keep your body healthy. Did you know a baby is born with over 300 bones, but an adult only has 206 bones?
Bones are the individual pieces that create the Skeletal System.
Without bones we would just be a puddle of skin and guts on the floor! Four Functions
of a Bone What is a Bone made of? Underneath the Outer Layer is a spongy material, almost like honeycomb, which is much lighter and slightly flexible.
In the Center, bones contain a jelly-like substance called Bone Marrow which is constantly producing new blood cells. A bone has 3 layers:
The Outer Layer is very hard and compact, which means it is very strong, dense, and tough. The Spine The is the central support of the body.
It's made up of smaller bones called Verebrae which are separated by cartilage to keep the bones from rubbing against each other.
There are 26 Verebrae in the human body. Ribs "Your rib cage is made up of 12 Vertebrae, 24 ribs, and a breastbone in 3 parts. It protects your heart and lungs from knocks and bumps." Hands & Feet Your foot has 26 bones (tarsals, metatarsals, and phalanges).
Your hand has 27 bones (carpals, metacarpals, and phalanges).
These bones are EXTREMELY flexible! Shoulders & Arms The Skull The Skull protects our brains and sensory organs.
It consists of 22 bones, 8 of which form the cranium, leaving 14 to form the face.
A baby's skull doesn't fuse together until age 2, allowing room for it to grow and change. Cranium Facial Bones Phalanges Humerous The clavicle and the scapula create your shoulder.
Your arms are formed by the radius, ulna, and humerus bones. Clavicle Scapula Ulna Radius Your lower arm is one of the most common broken bones in the world! Have you ever broken your arm? Hips & Thigh The largest and strongest bone in the human body is the Femur! The bones within the hips help us stand upright and move. Pelvic Girdle Femurs Knee & Lower Leg Tibia and Fibula are the two bones in the lower leg or calf.
The knee allows you to bend your legs which enable you to run, walk, jump, sit...anything and everything. Can you feel your patella or knee cap? Tibia Fibula Patella Broken Bones Your bones are tough stuff — but even tough stuff can break.
Like a wooden pencil, bones will bend under strain. But if the pressure is too much, or too sudden, bones can snap.
You can break a bone by falling off a skateboard or crashing down from the monkey bars.
There's more than one way to break a bone or fracture a bone.
A hairline fracture is a thin break in the bone, but bones can also be snapped in two pieces like a tree branch after a storm.
No worries, though! It only takes 4 to 6 weeks for a broken bone to heal with the help of a cast and/or crutches. Bone Health We know bones are strong, but how to they stay strong?
Bones need vitamins like:
Vitamin B6 and B12
Healthy bones give you more mobility, flexiblity, and strength! Bone Dance http://wallwisher.com/wall/bloominbones Put Your Skulls Together! Adaptations ELL Learners
I would add the Spanish word for each bone in the Skeletal System on my Prezi then work with them individually or in a group when answering Bloom's questions. I could also provide an extra worksheet/glossary for Spanish to English terms on the Skeletal System.
Learners with Disabilities
Most students do better with a hands on activity, by working with others, or strictly by hearing - all of which are included in my presentation with an interactive game, a music video, and questions for student collaboration.
I would expand even more on the Skeletal System for these students. Every student learns differently, but every student can learn with the help of 21st Century technology because teachers can now meet each student’s needs. Programs like PowerPoint, Prezi, and SlideRocket keep student’s attentive and active in learning, rather than being bored by plain ol’ lecture. By including images, videos, interactive teaching games, and student collaboration with Web 2.0 tools in these presentations we can successfully reach each student on their level. These tools not only give students a different view of what they are learning, but it also gives us feedback on how much a student has learned or what they need to focus on more. My lesson on the Skeletal System includes several of these methods which meet 21st Century Learning standards. 21st Century Learning GLE: 1C Grade 3
