Skeletal System Labeling

The skeletal system is the support structure of the body, it gives the body its shape.

The main parts of the skeleton that need to be labeled are the skull, the rib cage, the tibia, the humerus, the spine, the pelvis, the radius, the femur, and the fibula.


Nervous System Worksheet

The nervous system is the command center of the entire body. Starting at the brain it controls everything you feel, see and think.

The words that the children will learn when using our nervous system worksheets are the brain, the brain stem, the cerebellum, the spinal cord, and the nerves.


Respiratory System Labeling Printable

The respiratory system is what helps us breathe.

The new words included in this worksheet are the nose, mouth, larynx, trachea, and the 2 lungs.


Circulatory System Labeling Worksheet

The circulatory system pumps the blood from the heart to the lungs to get oxygen. The heart then sends that blood around the body.

The words that need to be labeled are the vein, the heart, and the artery.


Digestive System Activity

The digestive system turns the food and drinks we eat into nutrients and energy we need to survive.

The words the kids need to label are the mouth, the small intestine, the large intestine, the esophagus, and the stomach.
