2 12 Puffy Head, Bird Legs Information for Teachers GENERAL LESSON OVERVIEW This lesson gives students the opportunity to learn about the effect of gravity on their own bodies by shifting their body orientation from head upwards to feet upwards. Observable and measurable effects occur within 10 minutes. Lesson Opening: Fill a plastic glove with red colored water (see the Blood Flow in Space activity) and draw a face on the wrist of the glove and feet on two of the fingers. Hold the glove with the wrist up and ask students to observe where the blood pools in the glove (in the fingers/ feet ). Ask students if they have ever had their feet swell while standing for a long time and allow them to share some personal experiences. Then ask students what would happen to the blood in the glove if you hold the glove by its feet ( blood runs into the wrist/ head ). Demonstrate the fluid shift in the glove when it is held by the fingers, and ask students if they think that blood pools in the lowest part of their own bodies when they change orientation. At this point, students are ready to begin the activity to answer the question: How does gravity affect blood circulation and the distribution of fluids in the body? Teacher Directed Instruction: Show students the laboratory materials and demonstrate the testing position for measuring fluid shift in the human body. Emphasize the importance of measuring the calf circumference at the same point before and after the test interval. This laboratory is written for groups of 2-3 students who should be able to measure in millimeters, follow written directions, and perform basic mathematical calculations. Students with cardiovascular problems or who aren t feeling well should not be the test subjects. Structured Inquiry: All students will be following the same procedure, but their ideas, explanations, and body responses will differ. Be sure that students are not forced into documenting change in appearance and calf circumference that they do not see. Scientific integrity is more important than confirming an expected result. A few people show little or no change after 10 minutes. This lack of change is an example of the diversity of human adaptation to changing conditions. Collecting data from the entire class provides the opportunity for students to compare individual data to group trends. Conclusion: Ask students to relate their observations of body changes to changes in body orientation. Did they see any differences in the physical characteristics of person before the test compared to after the test interval? Also ask students to describe how their hypothesis compared to their results. Finish your discussion with connections between the puffy head, bird legs of astronauts and the changes that are expected in patients who must lie in bed for days at a time. Ask students to compare the fluid shift in long term bed rest patients to the fluid shift in astronauts in microgravity conditions. Encourage students to go to the NSBRI web site to find out more about measuring fluid shift.

3 Puffy Head, Bird Legs 13 BACKGROUND INFORMATION Gravity helps to push blood downward into the legs and feet of a person standing on the surface of Earth. The human circulatory system must use energy to pump blood upwards counter to gravitational force. When a person lays down with both legs straight up, gravity acts to push blood from the legs and feet toward the head and chest. If this position is maintained for several minutes, the legs lose a significant amount of their volume through the loss of fluid and will become thinner. The head will gain blood and fluids. Veins are likely to protrude and become more visible. The head will become bloated with the extra fluid and appear fuller. A similar fluid shift from the lower extremities to the upper body occurs in astronauts while in the microgravity conditions of space. The facial appearance of astronauts on Earth is noticeably different from that in space. In addition, their legs become thinner in microgravity; thus, the terms puffy head and bird legs. The fluid shift change can also cause an increase in astronaut sinus pressure creating the feeling of a stuffy nose and affecting their sense of smell. Upon returning to gravity conditions on Earth, the head resumes its normal appearance, and the legs revert to normal size. A longer stay in space can result in more lasting changes. After the fluid shift to the upper body, excess fluid is removed by the kidneys and the body establishes a new equilibrium with a decreased total volume of blood. With less blood to pump, the heart can decrease in muscle mass due to reduced workload. The prolonged thinner condition of the legs combined with the greatly decreased use of the legs in microgravity compared to Earth can lead to reductions in muscle mass or atrophy. If the human body were exposed to the opposite conditions (an increase in gravity compared to Earth) the gravitational force on body fluids would be greater. More blood would flow into the legs and feet, increasing their volume with a corresponding decrease in blood from the upper body and head. Until the body could compensate, there would be less fluid in the head and it might appear thinner. MATERIALS Metric tape measure Exercise pad or blanket (optional) Clock with a second hand Chair TEACHING HINTS Prompt the students to notice the texture, color, and shape of the head. Such descriptive words as lean, muscular, firm would be appropriate. (The head change is more easily observed in slimmer subjects.) Ten minutes can be a long time for students to wait patiently for a change in leg circumference. Give your students a short activity to complete while they are waiting, such as finding out how the human body maintains blood flow to the head or finding out how lividity in a corpse tells police about the position of the person at death. It is important to measure the before and after leg circumferences at the same place on the leg. A mark on the subject s calf could be made with a piece of tape or a small ink mark.

4 14 Instead of having students plug numbers into the % change equation without thinking, have students look at % change of the circumference of a balloon losing and gaining air. Be sure they easily distinguish between positive change (increasing circumference) and negative change (decreasing circumference). If you don t have tape measures, calf circumference may be determined by using string, which is marked, then measured on a meter stick. A transparency of the data tables is helpful to display the data and assist the students in compiling the data from the various groups.

5 Puffy Head, Bird Legs 15 ANSWER KEY FOR THE STUDENT DATA SHEET Hypothesis: (a) Accept any reasonable answer. One might expect a greater fullness in the head and face due to the extra volume of fluid being pulled towards the head by gravity. (b) Accept any reasonable answer. One might expect a decrease in leg volume due to gravity s pull of blood from the legs and feet. Data: 1. Answers should reflect the normal appearance of the head and face. 2. Answers are objective. An increased fullness would be expected. Blood vessels might become more prominent. 3. Answers will vary. Subject may report feelings of stuffiness in the sinuses and fullness or heaviness in the head. 4. Answers depend upon the experimental data. 5. Answers depend upon the experimental data. (A decreased circumference from #4 is expected.) Data Table: Answers depend upon experimental data. Use the following formula for determining percent change. % change = (Post Test Circumference - Pre Test Circumference) X 100 Pre Test Circumference Calculation Example: If your calf had a circumference of 350 mm while sitting, then a circumference of 340 mm after 10 minutes of leg elevation, then, the % change would be: % change = ( ) X % change = (-10) X % change = % (note: three significant figures) In this example, the calf circumference decreased almost 3% indicated by the negative sign in the % change. Though individual measurements will vary, no student s calf circumference should increase. Students must not contract their leg muscles during measurement, and should measure exactly the same place on the calf for pre and post test data. Expected Conclusions: 1. Yes. Changes were due to gravitational force on the fluid in the legs causing a fluid shift to the head. 2. Yes. Decreased calf circumference is due to gravitational force on the fluid in the legs causing a fluid shift from the legs to the head. 3. The fluid that pools in the legs and feet at 1 G shift throughout the body when gravity is reduced. The result is more fluid in the head and chest, with less in the legs and feet in microgravity. (There are also cardiovascular effects with longer exposure to microgravity environments.)

6 16 4. No. Gravity would again exert an Earth-normal pull on the body fluids. The extra fluid in the head would be pulled downward. The decreased fluid in the legs would again be supplemented by the downward pull of gravity on the body fluids. (Note: If the astronaut has spent more than one month in space, it would take several days for the body to regain its normal volume of fluids. This is because, in space, the kidneys have eliminated what they perceive to be an excess of body fluid.) Going Beyond: 1. The astronaut s head and face would appear more stark or thinner due to gravity s greater pull of fluid downward from the head. 2. The astronaut s legs would have a greater circumference because the increased gravity would pull more fluid into the feet and legs. 3. A digital camera may be used to take photos of student faces both before the test and at the end of the 10 minute test interval. Be certain to take the photos from the exact same distance and to take the photo before the student changes position at the end of the 10 minute test. Quantitative measurements can be made from the printed photos to demonstrate how much change occurs in the face before and after the experiment. ASSESSMENT Performance Tasks A performance task could be used to assess science inquiry skills. Examples: 1. During a test, pass around two balloons of different sizes and labeled before and after with a measuring tape and questions about the % change in circumference and whether the change was an increase or a decrease; 2. Give students a list of class before and after data, ask them to graph the data and summarize the group trends. 3. Give students a scenario including hypothesis and results similar to this lab, and ask students to describe how the results verified or disproved the hypothesis.

7 Puffy Head, Bird Legs 17 Puffy Head, Bird Legs Student Activities PROBLEM How does gravity affect blood circulation and the distribution of fluids in the body? BACKGROUND Gravity helps to push blood downward into the legs and feet of a person standing on the surface of Earth. When a person lies down with both legs straight up at a 90 o angle, gravity acts to push blood from the legs and feet to the head and chest. A similar fluid shift from the lower extremities to the upper body occurs in astronauts while in microgravity conditions (one millionth of Earth s gravity). In this activity you will model on Earth the distribution of blood toward the upper body that astronauts experience in microgravity conditions in space. MATERIALS Metric tape measure Exercise pad or blanket (optional) Clock with a second hand Chair PROCEDURE 1. Work in groups of two or three. Select one of the members of the group to be the test subject. 2. With the test subject in a sitting position, observe the facial shape and skin features. Record your description on the Student Data Sheet. 3. Measure the circumference of a calf at its widest point to the nearest millimeter. Record the data on the Student Data Sheet. (Note: Mark the level on the calf where the measurement was made, so the calf will be measured at the same place at the end of the experiment.) 4. Have the subject lie down, with her/his back to the floor and legs against the wall at a 90 o angle to the torso. Have the subject maintain this position for 10 minutes 5. Observe and record facial shape and skin features while the subject is still in the test position. 6. Ask whether the subject has any unusual feelings in the head and face, and record his/her responses. 7. With the subject still in the test position, measure the calf circumference at the same location as the pre test measurement. Record your data on the Student Data Sheet. 8. Calculate the percent change in the calf circumference and record your results. 9. Gather leg circumference data from the other groups and enter the data on the Group Data Sheet. 10. Design a double bar graph to display the pre- and post-data collected from each test subject in the class. 11. Write your conclusions. Correct Position for Puffy Head, Bird Legs

Describe the facial shape and skin features at the end of the experiment. 4. Did the test subject report any unusual feelings in the head and face? If so, describe them. 4. What was the circumference of the calf after elevation (to the nearest millimeter)? 5. What was the percent change in the circumference of the subject s calf? EQUATION: % change = (Post Test Circumference - Pre Test Circumference) X 100 Pre Test Circumference

9 Puffy Head, Bird Legs 19 GROUP DATA TABLE: Compile data on the circumference of calves of test subjects before and after leg elevation. Student Name Pre Test (mm) Post Test (mm) % Change GROUP DATA GRAPH: Remember to title and label your graph, including units of measurement.

10 20 CONCLUSIONS: 1. When a person s legs are raised above the head and torso, do you observe any head and facial changes? If so, why do you think these changes occurs? 2. When a person s legs are raised above the head and torso, do you observe any change in calf circumference? If so, why do you think this change occurs? 3. How would circulation be affected if gravity weren t forcing blood down into the legs and feet of a standing person? 4. An astronaut with a puffy head and bird legs returns to Earth, after a short time in space. Would you expect these changes in his body to be permanent? Why or why not? Going Beyond: 1. If an astronaut walked around on a planet with 2 G (two times the gravitational pull of Earth), what changes would you expect in the face and head? 2. On the same 2 G planet, what changes would you expect in the circumference of the legs?
