  1. Modeling Activities for Human Body SystemsMichelle Varnau St. Lawrence Elementary and Middle School Santa Clara, CA

  2. Modeling Activities • Models with Inquiry Purpose • 5th & 7th Grade CA State Science Standards • Next Generation Science Standards • Sample Models • Osmosis Cell Containers • Lung Bottles • Respiratory Disease Straws • Skeletal Pasta • Rubber Band Tendons • Intestinal Tapes • Esophagus Model Lab • Resources

  3. Inquiry with Models 1998 California State SS 2013 DRAFT Next Generation SS Students demonstrate understanding… Students Know… • Going beyond labeled pieces of a model. • Student construction and creativity skills. • Using science and engineering practices.

  4. Cell Models Osmosis with tubing connectors Diffusion with Food Coloring

  5. Respiration Models Respiration Disease Straws Demonstrating breathing with constricting airways. Lungs Bottles Without using a y-connector, how can two small balloons be added?

  6. Skeletal Models Rubber Band Hand Tendons – overuse with typing and video game movements Skeletal Pasta Backbone model then deciding how to attach the other bones.

  7. Digestive Models Intestinal Tapes Measure out distance of digestive track with old video tapes or adding machine paper. Esophagus Balloon Model Sample Kit

  8. Model Materials Rocket balloon, scissors, marbles, liquids, and hand motions Esophagus Model Esophagus Location Measure about 25cm from throat to chest area. Predicting Ease of Peristalsis Motion dry, water, dish soap, oil

  9. Dry Balloon Repeat with smaller marble. Notice hand movement needed to get sphere down the tube. With ends of balloon cut off, work in pairs to move marble through dry balloon.

  10. Wet Balloon Repeat peristalsis movement with larger marble in the tube. Place marble and balloon in a small bowl of water to allow the inside to be completely wet. Use towels for clean up of extra drips. Notice if it is easier or harder than the dry balloon.

  11. Wet Balloon Add a few drops of dish soap on the inside of the balloon and spread around. Repeat peristalsis motion with marble and notice if easier or harder or the same as the water.

  12. The Real Esophagus • Saliva’s Role • Small Portions • Smooth and Striated Muscles Involuntary Muscles

  13. Resources Materials Curriculum • Reuse or Recyclable Materials • Restaurant Supply and Toy Stores • ESS • AIMS • RAFT
