6th grade window air conditioning model
The 6th graders have been learning about thermal energy transfer, by discovering how an air conditioner works. They are learning what happens at the molecular level. Seeing all of the parts and understanding what they do was a little overwhelming until they built models out of Lego bricks and pipe cleaners. The various colors allowed them to really see the energy transfer that takes place.
