Activity #21-22: Heart Pump and Muscle

Today students examined how are heart is like a pressure bulb. They both have valves, they both pump in one direction, and they both pump liquids. Students experimented with two pumps to find out these characteristics of the heart. Next, students examined how our heart is a muscle. We first did 4-corner vocab to define muscle, draw a picture, and use it in a sentence. Next students looked at how our heart is like a muscle which contracts and expands to pump blood throughout our body. Finally, students RAPP a paragraph of how our heart is like a pressure bulb.
