This in an interactive activity in where students read graphs their peer’s heart rate during baseline line data for regular beats per minute (BPM), for a one minute session of jogging in place, and heart rate until it returns to its normal resting place. It is important for students to know how to read graphs because in various career opportunities reading graphs is a necessity. For example, a doctor read graphs on his or her students medical charts, a mechanic reads a graph from data gathered from scar diagnostics tool, a self-employed business man creating a profits graph during summer months, and so many more. Students’ heart rate will be measured using a Hand-Grip Heart Rate Monitor recorded in a graph on a TI-83 or TI-84. This activity aligns to CCSS.MATH.CONTENT.HSF.IF.B.4 in which students will copy each individual student’s heart rate vs. time graph on the worksheet, and then use the graph to explain the relationship between the two quantities by explaining the intercept, places where the graph in increasing or decreasing, the relative maximum, end behavior, periodicity, and (if applicable) symmetries.
After the first student’s at rest BMP is noted, student will run in pace fast, and then let a minute to a minute and a half to recover. (Note: For all the above steps student must be holding on to the heart monitor at all times and in the correct way—the hand monitor arrow is facing up and toward the sensor, which is also facing up).
Example graph is shown below:
Materials needed for the activity:
- Hand-Grip Heart Monitor
- TI-83 or TI-84 graphing calculator with EasyData Program
- Projector
- Heart in Motion!
This activity was made for only needing one heart monitor and one Ti-83 or TI-84 graphing calculator. The students take turns going up and checking their heart rate at rest, then when running fast in place, and again at rest. The Heart in Motion! Worksheet can be printed “x” number of times; where x = the total number of students in your classroom.
