Using Vernier Digital Probes in AHS Anatomy and Physiology

Q&A with Arlington High School Science Teacher Cory Bavuso on using Vernier digital probes with Anatomy and Physiology students

Vernier probes are computerized measuring devices that capture Vernier Probesdata via specialized sensors. Cory Bavuso describes how she has been using Vernier digital probes with her students.  AEF hopes to purchase more of these probes for the science department as part of the AEF Technology Initiative 2015 fundraising effort.

How are Vernier digital probes used in your classroom, and what are their benefits to students?

Vernier has designed a wide variety of probes, all of which may be attached to a handheld “LabQuest” interface. The interface graphs data collected by the probes. We use the EKG sensors and heart rate monitors in anatomy & physiology class.

What do the probes allow you and students to do that you couldn’t Vernier Probes2have done without them?  What do they teach students?

Vernier probes have been great for anatomy & physiology. They allow us to conduct many of the experiments that would be done in an exercise physiology lab, without the expensive equipment.

Why do you need more of these probes? 

Right now I have a few heart rate monitors and EKG probes. These allow the students to do labs relating to the cardiovascular and muscular systems. There are many labs we cannot do because we lack the correct probes. I’d love to have the chance to do labs with spirometers, accelerometers, blood pressure sensors, and surface temperature probes.  More advanced labs will often combine multiple probes, allowing students to collect and analyze data regarding multiple variables. For example, if a student is exercising, it is possible to measure VO2 max, changes in blood pressure, and heart rate simultaneously.

What about the project is most fun and exciting for the students?Vernier Probes3

Students love to be the test subjects of their experiments. Learning about how the heart works is interesting and important; actually measuring electrical activity in your own heart makes the subject matter fun and exciting.
