Welcome to Smile and Learn! Today, we’re going to discover something amazing about our bodies: the skeletal system. This is all about the bones, joints, and cartilage that make up our body.
Bones are like the hard building blocks that hold up our body. Imagine if you didn’t have bones; you would be as wobbly as jelly or a jellyfish! Bones give us shape and help us stand tall.
Joints are the special places where two bones meet. They let us move our arms, legs, and other parts of our body. Thanks to joints, we can run, jump, and play!
Cartilage is softer and more bendy than bones. You can find it in your nose and ears. It helps cushion our joints and makes sure our bones don’t rub against each other.
When the skeletal system works together with the muscular system, they form the locomotor system. This system helps us move around and do all the fun activities we love.
Did you know we have more than 200 bones in our body? Some of the important ones are the skull, which protects our brain, and the spine, which helps us stand up straight. We also have the humerus in our arm, ribs to protect our heart and lungs, and the femur, which is the longest bone in our body.
There are many other bones, like the jawbone for chewing, vertebrae in our back, clavicles near our shoulders, and the shoulder blade. We also have the ulna and radius in our arms, the sternum in the chest, the pelvis for sitting, the kneecap for bending our knees, and the tibia and fibula in our legs.
We’ve learned so much about bones today! But there’s still so much more to discover. Imagine all the fun facts you can learn by watching more videos. Don’t forget to subscribe to the Smile and Learn educational channel to keep learning and having fun!
Bone Detective: Go on a bone hunt around your house or classroom! Look for objects that are similar to bones in shape or function. For example, a chair leg can be like a femur because it helps support weight. Draw or take pictures of the objects you find and explain why you think they are like bones.
Joint Movements: Try moving different parts of your body and notice how your joints help you. Can you bend your elbow? Wiggle your fingers? Jump up and down? Write down or draw the different movements you can do and the joints that help you do them. Discuss with a friend or family member how these movements would be different if you didn’t have joints.
Cartilage Experiment: Find a piece of soft clay or playdough and a small plastic spoon. Press the spoon into the clay and notice how it sinks in. Now, place a thin piece of cardboard between the spoon and the clay. Press again and see how the cardboard acts like cartilage, cushioning the spoon. Talk about how cartilage helps protect our bones in a similar way.

Welcome to Smile and Learn!
Today, we’re exploring the systems of the human body, focusing on the skeletal system. The skeletal system is composed of bones, joints, and cartilage. Bones are hard structures that support our entire body. Without bones, our body would be very flexible, similar to jelly or a jellyfish.
Joints connect our bones and allow for movement within our skeleton. Cartilage is softer and more elastic than bones, and you can find it in areas like your nose and ears.
Together, the muscular system and skeletal system form our locomotor system. Did you know that we have more than 200 bones in our body? Some of these include the skull, spine, humerus, ribs, and femur.
Other important bones include the jawbone, vertebrae, clavicles, shoulder blade, ulna, radius, sternum, pelvis, kneecap, tibia, and fibula.
We’ve learned so much in just one video! And there are many more videos to explore. Imagine how much more you could learn!
