This activity investigates the relationship between heart rate and exercise and students write a CER argument to explain this relationship. This can be used to teach about the circulatory system, cellular respiration, exercise and health, and homeostasis of the body.
Students take their resting heart rate and then do 1 minute of exercise and measure their heart rate again. Students then read a passage about changes in heart rate then write an argument to explain how exercise affects heart rate.
This comes from my “Quick and Cl-Ev-R” series. Each activity is designed for students to practice writing scientific arguments with Claim, Evidence, and Reasoning based on real world data and experiences. Each activity includes a quick hands on activity or demonstration, data collection, and corresponding reading focusing on the scientific concepts presented in the activity.
