In this activity, you will collect data, collate it, and visualise it. Roles that need to be filled: 1. A volunteer to do some jogging on the spot 2. A timer (someone will need a watch or a phone) 3. Someone to record measurements Instructions: 1. Measure the resting heart rate of the volunteer 2. The volunteer must jog for 30 seconds. After this, 30 seconds, record their heart rate. 3. As soon as the heart rate is recorded, the volunteer must jog for 30 more seconds. Record their heart rate again. 4. As soon as the heart rate is recorded, the volunteer must jog for 30 more seconds. Record their heart rate again. Record the data in a table like: Heart Rate Time Resting heart rate (t 0) First set of 30 seconds (t - 30) Second set of 30 seconds (t-60) Third set of 30 seconds (t -90) Now: 1. Take your data points and think about how you could display this data. Make a visualisation of the data points. 2. Look at the starting and end points. What differences can you see? 3. Do you think, if you continue to do this process, the heart rate of the volunteer will continue to increase uncontrollably? Why or why not? 4. Do your data points seem to show some kind of function? Week 2 (Functions & Visualisation) This response should be no longer than 1 A4 page (not including graphs or tables). This response relates to criterion 1 (mathematical understanding), criterion 2 (reflection), and criterion 4 (communication of mathematics) in the grading rubric for this assessment task. In your own words (in no more than 150 words), provide an answer to the question "What is a function?". As part of your answer, state how you can identify a function just from looking at a visualisation or a graph. In the heart rate activity, do you think that a function exists that relates heart rate to the amount of time jogging? Why or why not? Are there any limits or assumptions to deciding whether or not a function exists. If you think a function exists, state what you think this function would be. As part of your response, show the data you collected during the activity and visualise the data collected. Reflect briefly (no more than 100 words) on the process of deciding whether a function exists or not for the heart rate activity.
