  • Comparing external body parts. 
  • Distinguishing the functions of external body parts. 
  • arm
  • foot 
  • hand
  • head
  • leg
  • trunk
  • worksheet 

Students identify body parts.



On the outside, our bodies are separated into the following obvious parts, head, torso, arms, and legs.  Each major part has a specific function.  The legs are used for locomotion like walking, running, jumping, and swimming.  The arms are used for holding things, lifting, pushing and pressing.  The torso or body trunk (the area between the head and legs) is used to bend and twist our bodies around.  The head contains the brain which is the "control center" of the body.  It tells us what we see, hear, smell, taste, and touch

Students have looked at what is inside their bodies, unfortunately, we cannot see these parts because of the skin.  All of the internal body parts provide the "energy" needed to make the outside body parts work.  Without muscles and bones we could not walk, sit or have any movement.  Without the stomach system we could not digest food.  Without the lungs we cold not get the oxygen which we need.  Without the brain we could not have the "directions" to make everything else work. 

  1. Distinguish for students the difference between internal and external body parts.
  2. Use the worksheet to have the students write the body part next to the part in the corresponding diagram.  Discuss the function of each of the body part.
