The title of the graph should include the variables being graphed. So, for instance, "The Effect of Different Types of Physical Activity on Heart Rate" might be a good title for this graph.You need a vertical (Y-axis and horizontal (X-axis), and these axes need to have numbers on them in uniform increments (or scales). For example, if you observed that the person's heart rate ranged from 60 beats per minute to 180 beats per minute, that is a range of 120 beats per minute. You could setup the scale such that each increment on the axis represents 10 beats per minute. If you are using graph paper, this would require 12 boxes if you are starting the axis at the lowest level of 60 beats per minute, or this would require 18 boxes if you are starting the axis at 0 beats per minute. You may choose to do either. If you think your graph looks too crunched with those scales, you can always have each increment represent 5 beats per minute. This will extend the size of the Y-axis. The choice is yours. Since you observed heart rate as the dependent variable, remember to place this variable on the Y-axis.
Dependent variables will always be placed on the Y-axis.
• For bar graphs like this one, the scale for the X-axis just needs to be the different categories you used. So, "Rest", "Light Activity", "Moderate Activity", etc. For bar graphs, you do not need to use numbers for your scale.• Your axes always need labels to allow a person reading the graph to quickly' determine what each axis represents.
• Also, for axes that have numbered scales, these labels should include the units in which you measured the data.
• For example, for the Y-axis, "Heart Rate (beats per minute" would be an appropriate label and units. Notice how the units are placed within parentheses. For the X-axis, "Activity Level" would be okay.
Plotted Data:
• Finally, once you have set up the axes, you are ready to plot your data.
For a bar graph, you just need to find the heart rate for that activity level and create a bar that rises from the bottom of the y-axis to this point on the graph.The last thing that needs to be added to the Results section is a short paragraph describing how the experiment went. Was there anything that happened during the experiment that could have compromised the results? Were there any results that you measured that surprised you? If so, explain why they surprised you. Were there any interesting and unexpected phenomenon that you noticed while you were collecting data? If so, describe it and the conditions that triggered it. Was it repeatable? If so, how did you get it to repeat. If, on the other hand, everything went according to plan with no surprising results or interesting phenomenon observed, you can also state this as well.
This paragraph allows you to convey to another scientist how you think the experiment went while you were collecting the data and if there are any interesting observations that should be explored more deeply.1. How did you select which feedback mechanism in the human body to study?
2. What was the most difficult part of planning or conducting your investigation?
3. Do you think your answer is the only right answer? Explain.
1. In selecting the feedback mechanism in the human body to study, we considered factors such as its relevance to our research question and its potential for yielding meaningful results. We also took into account the availability of resources and previous studies conducted on the topic to inform our decision.
2. The most difficult part of planning or conducting our investigation was determining the appropriate variables to measure and control. We needed to ensure that our experiment was well-designed to isolate the effects of different types of physical activity on heart rate, while minimizing any confounding factors. This required careful consideration of the experimental procedure and careful control of variables such as subject selection, activity intensity, and duration.
3. No, we do not believe that our answer is the only right answer. Scientific research and understanding are constantly evolving, and different studies may yield different results or interpretations. Our findings contribute to the existing body of knowledge on the topic, but further research is still needed to fully understand the complexities of the feedback mechanism in the human body related to physical activity and heart rate.
1. The decision to study the feedback mechanism in the human body was based on its relevance and significance in understanding physiological processes. Feedback mechanisms play a crucial role in maintaining homeostasis and regulating various bodily functions. By studying this mechanism, we can gain insights into how the body responds and adapts to changes in the environment or internal conditions.
2. The most difficult part of planning or conducting the investigation could be the selection of the variables and designing the experiment. It requires careful consideration of the research question, identification of appropriate variables, determining the methods of data collection, and ensuring the validity and reliability of the experiment. Additionally, controlling external factors that may influence the results and analyzing the data effectively can also pose challenges.
3. No, my answer is not the only right answer. The selection of the feedback mechanism to study and the difficulties faced during the investigation can vary depending on individual perspectives, research goals, and the specific context of the study. There may be other equally valid choices or challenges that researchers may encounter in different investigations related to feedback mechanisms in the human body. It is important to consider multiple viewpoints and approaches in scientific research to gain a comprehensive understanding of the subject matter.
To answer the first question, "How did you select which feedback mechanism in the human body to study?", you may have chosen the feedback mechanism based on your research interests, previous knowledge, or the relevance of the feedback mechanism to a specific topic or problem you wanted to investigate. It is important to justify your selection by explaining why it is significant or how it relates to the overall research question.
The second question, "What was the most difficult part of planning or conducting your investigation?", can vary depending on the specific experiment or study you conducted. It is important to reflect on the challenges you faced during the planning and execution stages. Some common difficulties might include obtaining suitable samples or subjects, ensuring accurate measurements and data collection, dealing with unexpected variables or limitations, or managing time and resources effectively. By addressing this question, you can provide insights into the practical challenges associated with your investigation.
Regarding the third question, "Do you think your answer is the only right answer? Explain.", it is crucial to acknowledge that scientific research often provides multiple perspectives and interpretations. While your answer might be based on rigorous experimentation and analysis, there could be alternative explanations or approaches that could yield different results. Science encourages open-mindedness and continuous exploration of various possibilities. Therefore, it is important to explain that your answer represents the current understanding or conclusion based on your investigation, but it might not be the only valid interpretation or solution in the field.
