Welcome students! Introduce yourself and the lesson “Heart Rate Hero.” Explain that today we will learn how to measure our heart rate at different times and see how exercise affects it.

Read the lesson objective out loud. Emphasize why understanding heart rate helps them stay healthy.

Explain that heart rate is how many times the heart beats per minute. Mention normal teen resting range (60–100 BPM).

Show a simple diagram of wrist and neck pulses. Demonstrate finding the radial pulse on your own wrist.

Advance to next slide when students are ready. Hand out or direct them to the worksheet.

Explain the exercise: 2 minutes of jumping jacks at a steady pace. Model a few jacks if needed.

After 1 minute of exercise, pause and measure immediately to capture active rate.

Guide students to rest for 1 minute, then measure recovery rate.

Project this template on the board as an example. Encourage neat, accurate entries.

Use the questions to lead a brief class discussion. Call on volunteers to share observations.
