Main Curriculum Tie:
Background For Teachers:
Teachers should be familiar with the structures and functions of the organ systems of our bodies. The body puzzle is very useful for a quick brush up.
Student Prior Knowledge:
Intended Learning Outcomes:
Without any previous discussion, have the students work in pairs to solve the puzzle.
After the students have had enough time to complete the puzzle, call on students to read the function and structures of each organ system.
Discuss in more depth with the class about the circulatory and respiratory systems. If you have models of the heart and lungs that would be great.
Teach the students how to measure their heart rate by taking their pulse, either from their wrist (radial artery) or their neck (carotid artery) for 20 sec then multiplying by 3 to have beats per min (BPM).
Teach the students how to measure their respiratory rate by counting the number of breaths for 20 sec then multiplying by 3 for breaths per min (BPM).
Have the students measure and record their resting heart rate and respiratory rate.
In a place with enough space, have one student per group dance to the song YMCA with their arms for one minute. That student will measure his/her own heart rate and their partner will measure the 1st student's breathing rate. You will have heart rate and breathing rate for one student only at this point. This will be the intermediate heart and breathing rate.
Repeat the YMCA portion of the lab with the other student.
Have the first student now do jumping jacks for a minute. Have the student doing the exercise measure their own heart rate and their partner should measure the jumping jack students' breathing rate.
Repeat this exercise with the other student.
In small groups have the students exchange their heart and breathing rates for all phases of heart and breathing rate.
Students should now calculate the averages for their small groups.
Teach or review with the students how to make a graph. (The x and y axis and that all graphs should have an x axis title, y axis title, overall title.)
Finish with a discussion on the trends the students observed and how these organ systems work together, not independently.
