See-Through Body

See-Through Body lesson plan

What if you could you see inside yourself with X-ray vision? Use Crayola® Washable Window Markers or Crayola Window Crayons to create a life-sized look inside your body.

  • 1.

    The human body has more than 200 bones called the skeletal system. This network of bones has many important jobs. Your skeleton supports your body, protects internal organs, works with muscles to create movement, and contains cells that help keep your body healthy. Find out more about your skeletal system.

  • 2.

    Organs are two or more kinds of tissue joined together to perform a task. For example, your heart is a major organ whose job is to pump blood through your body. A group of organs forms an organ system. Find out the names and functions of your body's major organs.

  • 3.

    Can you imagine what all these bones and organs look like inside you? Find out by making a See-Through Body! Ask a classmate to use Crayola Twistables Crayons on craft paper to trace the outline of your body. When you finish tracing each other, use Crayola Scissors to cut out your outlines.

  • 4.

    Ask your teacher to help you find a large area of glass on which you can trace yourself. Tape paper to glass. Use Crayola Washable Window Markers or Crayola Window Crayons to trace the outline on the glass.

  • 5.

    Use the markers to draw major bones and organs in your body. If you change your mind, just wipe with a damp paper towel and draw again. Label each bone and organ if you like. Isn't the human body truly amazing?


  • Children research major organs and the skeletal system of the human body.
  • Students identify the function of human skeletal and organ systems.
  • Children create a life-sized outline of their bodies and draw the skeletal system and major organs inside.


  • Outline your body on paper. Make skin-colored flaps with Crayola Multicultural Crayons to cover each area. Underneath the flaps, draw major organs.
  • Create a giant puzzle of yourself using the life-size outline. Add details to your drawing. Cut the drawing into pieces. Ask a friend to put you back together!
  • Teachers are encouraged to use this project or an adaptation of it to assess children's knowledge of the human body at the end of a unit of study.
