LESSON ACTIVITY Grade Level - High School Biology Math Background - Algebra I Lesson: Students are in small groups and using the heart rate monitor and labpro; they will take their heart rates before and after engaging in light activity. (i.e. jumping jacks, one-arm push-ups, or unicycle riding) After engaging in the activity, students should take special notice of how long it takes for their heart rate to recover.

STUDENT ASSIGNMENT Every student will collect data and construct a graph that illustrates their heart rate before, after, and recovering from activity. After analyzing each others graphs, students should be able to deduce what characteristics of the graph correlate to principles of heart rate. Students will also work with ratios to extrapolate what their heart rate graph would look like if they had engaged in longer activity. Higher order learning will be stressed when students are asked on assessment whether data makes sense. (i.e. is this graph possible? Is this heart rate realistic?)
