I would like comments on this lesson plan please. I wrote it for one of my college classes and saw many people was needing lesson plans concerning the body. I hope this helps. Please let me know how it works. Thank you. Vicki
Science Lesson Plan
Grade Level: fourth
Topic: How oxygen travels through the body.
A. Phase 1: Lesson introduction
1. Tell the students we are going to demonstrate the way oxygen travels through the body.
2. Today we are going to learn how oxygen travels through the body. How does oxygen go from the lungs into the blood and through out the body?
B. Phase 2: The Open-Ended Phase
Let's demonstrate how oxygen travels through the body. Have two students be each side of the heart and go to the middle of the room. Have two students to be the lungs and go to the corner. Have two students be capallaries. Then have rest of the student line up behind the lungs. Need red circle to represent blood that had oxygen in it. When we breathe in oxygen it goes into the lungs. From the lungs where does the oxygen go? (into the blood) Have everyone walk to the lungs and hand them a red circle. Where does the blood go from the lungs?(in the heart) So take the red circle and to go is the left side of the heart. The left side pumps the blood into the body. Using the body parts we have here, where should the blood with the oxygen go? (the fingertips) At the fingers the oxygen is given to the muscle and the blood picks up carbon dioxide. Give the cappillaries your oxygen and get carbon dioxide. Where does the blood go now?(back to the heart) After going to the heart where can the blood get more oxygen? (the lungs) Go back to the lungs and get your carbon dioxide. What happens to the carbon dioxide? (breathe out) What is inhaled? (oxygen) The process starts all over again. Lets try it one more time.
C. Phase: The Convergent Phase
Can you tell me how oxygen is received? (breathing in) Where does the oxygen go? ( in the lungs) The oxygen leaves the lungs and goes to the body parts. What is oxygen exchanged for? (carbon dioxide) When the carbon dioxide is received where does it go? ( to the heart) From the heart, where does the blood get rid of the carbon dioxide? ( at the lungs) What have we learned today? (oxygen is needed in order to stay alive) Why can we not use carbon dioxide to stay alive? (carbon dioxide is the waste product of the oxygen) What makes carbon dioxide the waste product?( after the body uses the oxygen it becomes carbon dioxide) Why is come carbon dioxide not needed to stay alive? ( it is a waste product and too much could cause a sort of poisoning) What can we generalize about the oxygen and carbon dioxide in the body?( oxygen is needed throughout the body to make the body function. Carbon dioxide is the waste product of the body and released by exhaling)
D. Phase: Closure
Will tell me how the oxygen gets into the blood. (We breath in air that contains oxygen into our lungs. The blood picks up the oxygen in the lungs.) How does the blood go from having oxygen to carbon dioxide? ( the blood moves through the body. The oxygen is exchanged for carbon dioxide at capillaries) How does the body get rid of carbon dioxide? (the blood with the carbon dioxide travels back to the heart, then to lungs. At the lungs it is exchanged for carbon dioxide.)
E Phase: The Application
We are going write the journey of the oxygen through the body. Start at how the oxygen is received and end at how the carbon dioxide exits.
