Draw Inside the Human Body


Life-size chalk drawings of body systems decorate playgrounds and sidewalks while demonstrating new learning.


1. Locate pictures, models, and information about human skeletal, circulatory, digestive, and respiratory systems.

2. Find a safe outdoor location with ample space for students to lie on the surface and have room to draw. Mural paper may be used as an alternative.

3. Work with partners to trace body outlines with Crayola® Sidewalk Chalk or Sidewalk Crayons.

4. Individuals draw in the body system(s) they are studying.

5. Discuss, assess learning, then wash away with a garden hose or the next rainfall.

Safety Guidelines

Adult supervision is required for any arts & crafts project. Observe children closely and intervene as necessary to prevent potential safety problems and ensure appropriate use of arts and crafts materials. Some craft items, particularly beads and buttons, are potential choking hazards for young children. Avoid use of such small parts with children younger than 3 years. Craft items such as scissors, push pins and chenille sticks may have sharp points or edges. Avoid use of materials with sharp points by children younger than 4 years. Read all manufacturers' safety warnings before using arts and craft supplies.

Outdoor Crafts—Choose safe outdoor areas, away from traffic and dangerous equipment. Close adult supervision is required.


  • Observe take-apart models of internal organs. Encourage children to reassemble the models. Invite health care professionals to show sample X-rays.
  • For children with mobility challenges, a computer drawing program might be useful.
  • Ask students to invent games about body systems, such as creating a playground trail filled with health challenges and fitness decisions.
  • Young children and those with special needs may need assistance tracing bodies on ground surfaces. Assist as needed then invite them to draw major organs inside the outlines.
