DOK Level 2: Skill/Concept

Design a simple experiment to demonstrate the effect of exercise on heart rate using an EKG.

• Measure heart rate at rest and then immediately after 30 seconds of jumping jacks.

• Compare heart rates before and after drinking a cup of water.

• Observe changes in heart rate while holding breath for 20 seconds.

• Measure heart rate every hour, without adding any physical activity.
