Scenario 5: Exercise and Heart Rate Scenario: A student wants to know if the intensity of exercise affects their heart rate. They decide to measure their heart rate after different levels of exercise (walking, jogging, and running) for 10 minutes each.answer it, and find the step by step answering this the by step Making an observation: - Asking a question: - Formulating a hypothesis:- Performing an experiment:- Recording and analyzing results: - Drawing a conclusion: - Communicating the results:
Answer (1)
Answer:1. Making an Observation:The student notices that their heart seems to beat faster after exercising.e.g: After I run or jog, I feel my heart beating faster than when I just walk.2. Asking a Question:Does the intensity of exercise affect heart rate?e.g: How does the level of physical activity (walking, jogging, running) affect my heart rate?3. Formulating a Hypothesis:A hypothesis is an educated guess or prediction.e.g: If the intensity of exercise increases, then the heart rate will also increase.4. Performing an Experiment:Design a test to collect data. (Use the same person)Steps:Exercise types: Walking, Jogging, RunningDuration: 10 minutes eachAfter each activity, measure heart rateRest between each activity to return to resting heart rate5. Recording and Analyzing Results:Write down the heart rate after each type of exercise.e.g: Activity Heart Rate (bpm)Walking 90 bpmJogging 120 bpmRunning 150 bpm6. Drawing a Conclusion:Summarize findings based on the data.e.g: The data shows that heart rate increases as exercise intensity increases. Therefore, the hypothesis is supported.7. Communicating the Results:Share the findings with others.e.g: Create a chart or graph and present it in class orWrite a short report explaining the method and results
