Inquiry with Models
1998California State SS
Students Know…
2013 DRAFTNext Generation SS
Students demonstrate understanding…
o Going beyond labeled pieces of a model.o Student construction and creativity skills.o Using science and engineering practices.
Cell ModelsDiffusion with Food Coloring
Osmosis with tubing connectors
Respiration ModelsLungs BottlesWithout using a y-connector, how can two small balloons be added?
Respiration Disease StrawsDemonstrating breathing with constricting airways.
Skeletal ModelsSkeletal Pasta Backbone model then deciding how to attach the other bones.
Rubber Band Hand Tendons – overuse with typing and video game movements
Digestive ModelsIntestinal TapesMeasure out distance of digestive track with old video tapes or adding machine paper.
Esophagus Balloon ModelSample Kit
Esophagus ModelEsophagus LocationMeasure about 25cm from throat to chest area.
Model MaterialsRocket balloon, scissors, marbles, liquids, and hand motionsPredicting Ease of Peristalsis Motiondry, water, dish soap, oil
Dry Balloon
With ends of balloon cut off, work in pairs to move marble through dry balloon.
Repeat with smaller marble.
Notice hand movement needed to get sphere down the tube.
Wet Balloon
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.
Repeat peristalsis movement with larger marble in the tube.
Notice if it is easier or harder than the dry balloon.
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.
