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.

It is challenging to see the relationship between parts of a model because sometimes the connections and interactions are not clearly shown or explained.
Models are useful when studying multicellular organisms because they help us understand the complexity of how different cells work together to form tissues, organs, and systems.
In summary, throughout this unit, I have learned about cell structures, organelles, viruses, and the interconnections between different body systems. I have gained confidence in using models to understand these concepts, although it can be challenging at times to fully grasp the relationships between different parts. Overall, models are valuable tools in studying multicellular organisms as they allow for a visual representation of complex systems and help us understand how different parts work together.
Throughout this unit, I have gained a deep understanding of the intricate workings of the human body and the importance of cell structures and systems in maintaining homeostasis. I now feel confident in using models to explore body systems because they provide a tangible representation that allows me to visualize and comprehend complex concepts more effectively. By studying the various types of organelles found in cells and comparing cell structures across different organisms, I have developed a greater appreciation for the diversity and complexity of life. Moreover, exploring the role of cell membranes in regulating the transport of materials into and out of cells has emphasized the crucial impact of these structures on overall cell function. Additionally, learning about viruses and comparing them to living things has highlighted the unique characteristics of these non-living entities and the significant implications they have on both human health and disease.
One of the most challenging aspects of planning and conducting investigations was ensuring accuracy and consistency in data collection. It required careful attention to detail and precision to obtain reliable results. However, this process also allowed me to observe unexpected phenomena and surprising results, which provided opportunities for further exploration and deeper understanding. It was fascinating to witness how different body systems interact and work harmoniously to help an organism survive. Creating models of body systems and comparing them to actual body systems revealed the limitations and gaps in our understanding, while also highlighting the complexity and interconnected nature of these systems.
In conclusion, this unit has provided me with a comprehensive understanding of cell structures, body systems, and their interactions. I have learned to appreciate the value of models in visualizing complex concepts and their role in scientific investigations. By exploring the different aspects of cellular and body systems, I have developed a deep understanding of how the human body functions and the intricate mechanisms that support life.
Throughout this unit, I have gained valuable knowledge about the human body and its systems. One of the highlights was conducting an experiment to study the feedback mechanisms in the human body. I selected this topic because I wanted to understand how the body maintains homeostasis. The most challenging part of planning and conducting the investigation was designing appropriate activities to stimulate different feedback mechanisms. I had to ensure that the activities were safe and accurately reflected real-life scenarios.
During the experiment, I measured the participants' heart rate while they engaged in various types of physical activities, such as rest, light activity, and moderate activity. It was interesting to observe how the heart rate responded differently to each activity level. I recorded the data and plotted it on a graph, with the activity levels on the x-axis and the heart rate on the y-axis.
The results of the experiment revealed a clear pattern. As the intensity of the activity increased, the heart rate also increased. This demonstrated the body's response to increased demand for oxygen and energy during physical exertion. It was surprising to see the significant difference in heart rate between rest and moderate activity, highlighting the importance of regular exercise for maintaining cardiovascular health.
While conducting the experiment, I noticed that some participants experienced a delayed increase in heart rate during the initial stages of moderate activity. This observation intrigued me, and I plan to further investigate this phenomenon in future experiments. Additionally, the experiment showed me the importance of proper data collection and analysis in drawing accurate conclusions.
In conclusion, conducting the experiment on feedback mechanisms in the human body was a valuable learning experience. It allowed me to apply the knowledge gained in this unit to real-world scenarios. The experiment provided insights into how the body responds to different levels of physical activity, and I am excited to continue exploring and understanding the intricate workings of the human body through scientific experimentation.
