4th Grade Lung Lab 11/18/13

This week we are finishing up Chapter 5 on Systems of the Human Body. Today was lab day —  We used 2 balloons, 2 rubber bands, a water bottle, a straw, and modeling clay to model a lung and a diaphragm. The lung part was very easy to model — the diaphragm was much harder!! The sturdier the bottle the more likely the student was to make a working diaphragm. Lesson learned for this newbie Science Teacher — next year I will tell students to bring in 20 ounce Soda bottles, Sunny Delight bottles, or Gatorade! These were the ones that worked! Even though not all diaphragms were in working condition — I think we all had lots of fun and learned lots!!
