This is part 6 of a 7 part hands-on unit study on anatomy of the human body. Create a lung model, measure lung capacity, dissect a lung, play a respiratory relay race, and more! These lessons are geared toward 4th-5th grade level children and their siblings. They were created by another creative mom for our weekly homeschool co-op. We meet each week for 2 1/2 hours and have 33 children between the ages of 1-13. Use these fun lessons with your classroom, family, after school program, camp, or co-
