Lub Dub: Acting out the circulatory system

As part of our study of the human body, we have been learning about the circulatory system. This week, we watched some Magic School Bus and Bill Nye the Science Guy videos to learn about how the heart pumps blood around the body distributing oxygenated blood to all the cells. Yesterday afternoon we spent some time acting as blood cells, picking up oxygenated blood in the lungs and carrying it to different cells in the body, then picking up carbon dioxide to be carried out. We learned how to check our pulse and felt our resting heart rate (one of the students who did a science fair project on heart rates showed us the places to check), then jogged in place to see how our heart rate sped up. Then we created our own stethoscopes from cups, funnels and tubing, and listened to our partners' heartbeats. Finally, we compared our stethoscopes to real stethoscopes - and found that some of ours worked just as well!

And tomorrow, we get to hear from a Navigator parent who is a cardiologist!
