Central Idea: The human body is an intricate system that is constantly changing.
Students learned that the circulatory system is like FedEx. The red blood cells in the blood are constantly delivering oxygen, nutrients, and waste to different parts of the body. In order to understand this concept better, students assembled a complex game involving the circulatory system. The goal of the game is to deliver the oxygen and sugar/protein pieces to the cells, the CO2 to the lungs, and the waste produced by cells to the kidneys. 
In class discussions this week, questions about asthma and diabetes were brought up. Even though asthma is a lung condition, we were able to see how it would affect the entire body with the circulatory system in mind. Also, diabetes affects how the body uses blood sugar. In terms of our game, the red blood cells would not be able to give the cells the sugar. Therefore, there would be too much sugar in the blood at times.
On a different note, we had a few fun surprises this week! Sania decided to write a song at home about the skeletal system, and Sarah brought in a deer skull for us to look at. Avaia brought a bone in that she found at Roots and Shoots. Thanks for sharing! : )
