Free Skeletal System Labeling Worksheet
Understanding the human body starts with learning its foundation—our bones. This skeletal system labeling worksheet helps students identify key bones in a fun and interactive way.
Designed for hands-on learning, this free science worksheet encourages kids to label each part themselves, reinforcing their knowledge of anatomy.
Whether you’re exploring human biology at home or in the classroom, this printable makes studying the skeletal system both engaging and memorable.

What is the Skeletal System?
The skeletal system forms the framework of our body, giving it structure and support.
It consists of 206 bones, all working together to protect vital organs, allow movement, and store essential minerals like calcium.
Without our skeletal system, standing upright or even simple movements like walking and lifting objects wouldn’t be possible.
It also protects delicate organs—our skull shields the brain, while the rib cage guards the heart and lungs.
Now, let’s explore some of the most important bones in the body!
Skull
The skull protects the brain and supports the face. Made up of 22 bones, it includes the cranium, which acts like a helmet, and the facial bones, which form our jaw, nose, and eye sockets.
Fun fact: Babies are born with soft spots (fontanelles) in their skulls that allow their heads to grow and change shape during infancy!
Humerus
The humerus is the long bone in the upper arm, connecting the shoulder to the elbow. It plays a key role in arm movement, allowing us to lift, throw, and carry objects.
Fun fact: The phrase “funny bone” comes from the ulnar nerve, which runs along the humerus. Bumping it sends a tingling sensation down the arm!
Rib cage
The rib cage is made up of 12 pairs of ribs that wrap around the chest, protecting the heart and lungs. Some ribs are attached directly to the sternum (breastbone), while others are more flexible, allowing us to breathe and move easily.
Try this: Take a deep breath in and feel your rib cage expand—this is how it helps with respiration!
Radius
The radius is one of the two bones in the lower arm, located on the thumb side. It allows us to rotate our forearm, helping with motions like twisting a doorknob or turning a key.
Fun fact: The radius and ulna work together to allow your hand to move in different directions!
Spine
The spine, or vertebral column, is made up of 33 small bones called vertebrae. It supports the body, allows flexibility, and protects the spinal cord, which sends messages between the brain and the rest of the body.
Fun fact: Humans are actually slightly taller in the morning because the cartilage between our vertebrae compresses during the day!

Pelvis
The pelvis is a bowl-shaped bone that connects the spine to the legs. It supports the body’s weight when we stand, walk, and run, and it also protects important organs like the bladder and intestines.
Fun fact: Women’s pelvises are slightly wider than men’s to assist with childbirth!
Femur
The femur is the longest and strongest bone in the human body, running from the hip to the knee. It helps us stand, jump, and run, absorbing the impact of movement.
Fun fact: The femur can withstand forces up to 2,500 pounds—stronger than concrete!
Tibia
The tibia, or shinbone, is the larger of the two bones in the lower leg. It supports most of our body weight and helps with walking and standing.
Try this: Tap the front of your lower leg—you’re feeling your tibia, which sits just beneath the skin!
Fibula
The fibula is a thinner bone that runs alongside the tibia. While it doesn’t bear much weight, it helps with balance and muscle attachment.
Fun fact: The fibula is often used in bone grafts to repair other bones in the body because it can regrow after part of it is removed!

Label the Parts of the Human Skeleton
Our skeletal system labeling worksheet is a hands-on way for kids to learn these bones by labeling them on a diagram.
On this free printable science worksheet, students will see an unlabeled skeleton and match the correct bone names.
Using a model skeleton is a great way for kids to explore the human body in a hands-on way, reinforcing what they learn from the worksheet.
