What instructions can be given to someone to measure their breathing frequency in one 1 minute? Count her breathing frequency for 1 minute. 3. What will you do to make the results of your experiment more accurate? Please repeat once more. ACTIVITY 2 1. What will you do for 1 minute so that your legs form 90 degrees, and your hands touch your thighs? Ask one of your friends to sit quietly for 1 minute. 2. What instructions can be given to someone to measure their breathing frequency in one 1 minute? Count her breathing frequency for 1 minute. 3. What will you do to make the results of your experiment more accurate? Please repeat once more. Procedure ACTIVITY 3 1. What will you do for 1 minute so that your body forms a 180 degree straight line, but you need energy to support your body? ask your friend to stand up for 1 minute. 2. What instructions can be given to someone to measure their breathing frequency in one 1 minute? Count her breathing frequency for 1 minute. 3. What will you do to make the results of your experiment more accurate? Please repeat once more. ACTIVITY 4 1. What will you do for 1 minute so you can slowly move forward and in an upright position? Ask one of your friends to walk leisurely for 1 minute. 2. What instructions can be given to someone to measure their breathing frequency in one 1 minute? Count her breathing frequency for 1 minute. 3. What will you do to make the results of your experiment more accurate? Please repeat once more. Procedure ACTIVITY 5 1. What physical activity should you do for 1 minute if you want to go up and down from the ground floor to the top floor of a building? Ask you friend to walk up and down the stairs for 1 minute. 2. What instructions can be given to someone to measure their breathing frequency in one 1 minute? Count her breathing frequency for 1 minute. 3. What will you do to make the results of your experiment more accurate? Please repeat once more. ACTIVITY 6 1. What will you do for 1 minute in order to elevate your heart rate and make you arrive faster? Ask one of your friends to run for 1 minute. 2. What instructions can be given to someone to measure their breathing frequency in one 1 minute? Count her breathing frequency for 1 minute. 3. What will you do to make the results of your experiment more accurate? Please repeat once more. Result Write the result in the form of a table consisting of the names of students, body positions (laying down, sitting quietly, standing up), body activities (walking leisurely, walking up and down the stairs, and running), trials and the average of breathing frequency! Discussion Please answer the question by discussing with your group and write the answer! 1. Based on your observations, which body position has the highest breathing frequency? Breathing frequency is highest when standing, and lowest when lying down/reclining. 2. Please explain why ‘that’ body position has the highest breathing frequency? The lung has to pump less forcefully when the rest of the body is at the same level, when lying down, so pressure is less. When a person is standing, their diaphragm and chest muscles have to work against gravity to move air in and out of the lungs, which requires more effort compared to sitting or lying down. As a result, the breathing rate tends to be higher in the standing position. 3. Do you think body activities affect breathing frequency? Yes, it does. 4. Please explain why your answer, whether it is yes or no! Because based on the observation the result it has a different breathing frequency in each body activity. Climbing the stairs and running has a higher breathing frequency than walking. This can happen, because when we do heavy activity like exercise, our body's need for oxygen increases when expending more energy. Oxygen is required for aerobic cellular respiration, the process by which glucose is burned in living organisms to produce energy. Conclusion Based on the results of the experiments and discussions you have done, what can you conclude? In conclusion, various body activities or positions, including physical activity and levels of relaxation, can all affect breathing frequency by influencing the body's oxygen demand and carbon dioxide removal needs. Based on the table, the highest average of frequency of breathing is when we climbing the stairs and followed by running. This means our observation is inline with the theory.
