Grade 7: Week of January 3-7

Our new unit is the respiratory system, or the system whereby oxygen is used as energy in the body and then breathed out as carbon dioxide through the lungs. We are first learning about parts of the respiratory system and its functions. Students will explore vocal cords through the use of rubber bands to show vibration, and their own lung capacity. Students will learn how to perform the Heimlich maneuver in case of choking, and further examine the dangers of smoking. Due to inclement weather, we were not able to dissect the heart but will do so Friday - an interesting and informative activity for those who are not squeamish!
