The class created a candy blood model using Karo syrup, Red Hots, mini marshmallows and sprinkles.
To view the lesson: The 5th graders felt the effects of asthma by breathing through a straw and emphysema by breathing through a coffee stirrer.
The students dropped meter sticks and discovered the human body's reaction time when responding to a stimulus. They tried to grab the stick as soon as they saw their partner drop it and then measured at what centimeter their hand clenched it.

The students created circulation wheels to show the flow of oxygenated and deoxygenated blood through the human body.
To view the lesson: The students used pipe cleaners, clay, foam insulation, PVC pipe and paper to recreate the layers of the human bone.
Using the top of a 2-liter bottle (the chest cavity), a balloon (the lung), grocery bag (the diaphragm) and a rubber band, I created a working lung model for the class. When the bag was pulled down (or the diaphragm was contracted) air pressure decreased and the balloon expanded. When the bag was resting up (or the diaphragm was relaxed) the air pressure increased which pushed the air out of the balloon.
