Here are experiments our science specialists have selected to support the IB* topic.


Heart Rate

Experiment #15 from Investigating Biology through Inquiry

In this Preliminary Activity, you will use a Heart Rate Monitor to determine a subject’s heart rate. After completing the Preliminary Activity, you will first use reference sources to find out more about the heart, the cardiovascular system, and heart rate before you choose to investigate a researchable question dealing with heart rate. Depending on sensor availability and your interest, you might decide to use another sensor, such as a Blood Pressure Sensor, in addition to a Heart Rate Monitor. Some topics to consider in your reference search are:

  • heart
  • heart rate
  • cardiovascular system
  • physical fitness
  • maximum cardiac rate
  • homeostasis
  • sympathetic nervous system
  • parasympathetic nervous system
  • heart-rate recovery time
  • fitness index
  • baroreceptor reflex
  • diving reflex

Introduction to Neurotransmitters using AChE

Experiment #16 from Advanced Biology with Vernier

In this experiment, you will

  • Observe the reaction rate of acetylcholinesterase (AChE) found in heart tissue.
  • Compare the reaction rate of AChE from different fractions of heart tissue.
  • Observe the effect that the compound tacrine has on the reaction rate of AChE.
  • Generate a dose-response curve for the compound tacrine.
  • Estimate the effective IC50 of tacrine on heart AChE.
