Our Lungs

a) Definition
· We have 2 lungs; one on the left and another on the right.
· Wen we breathe in Oxygen, it goes into our nose, the windpipe and then into the bronchial tubes. It then branches into left and right which leads to the bronchioles. Here the Oxygen would be absorbed into our blood system. The heart would pump them throughout our body to assist us at doing activities.
· After doing activities, we now have Carbon Dioxide as a result of using the Oxygen. The Carbon Dioxided blood would flow back to the heart and then into the lungs which then be discharged into the environment. This is the exhale process.
· We then looked at Ze yan and Jing Kai's encyclopedia as well as Jin Nan's. The kids were amazed how black the lungs could be if a person lives near a polluted area. Thus, a smoker has very dark lungs. The lungs actual colour is pink.

b) Game: The Wheelbarrow
· Due to the haze, we played an indoor game.Ecah kid find a partner. One being blinfolded, the other would lead them walking to the end of the line passing the Sports Cone. Here, the other partner would give the blindfolded person a stick. He then has to hit a container. Upon the hitting, he would take off the blindfold cloth. The other partner now had to crawl using only his or her hands while the legs being held up by the other partner. This is a wheelbarrow. They enjoyed this game as it involves team work.
