Human Physiology Innovative Uses

John Melville, our Biology Staff Scientist, has found that our Goniometer is a great sensor for investigating running. As shown in the sample data below, students can use a LabQuest and the Goniometer to record joint angle data from the knee while running. The running waveform contains both a large and a small peak.

Vitamin B2, also known as Riboflavin, is a vital component of the cofactors that support all flavoproteins. The highest concentrations in the body are found in the liver, kidneys, and heart. This vitamin is very important to the heart because it plays a key role in allowing aerobic (oxygen-based) energy production to occur. A great…

Laura Cerletty, a physiology teacher at Whitnall High School in Greenfield, WI, and Stephen Biscotte, a physiology teacher at Cave Spring High School in Roanoke, VA , have developed an innovative way to compare two methods of measuring blood pressure using Vernier products. The Data Mark feature in Logger Pro and LabQuest app makes this…

Laura Cerletty, an anatomy and physiology teacher at Whitnall High School in Greenfield, WI, and her students modified our CO2 to O2 Tee for improved performance when connecting the Oxygen Gas Sensor to the Spirometer. We were inspired to create the new O2 Gas Sensor to Spirometer adapter that replaces the CO2 to O2 Tee.…

We recently visited Dr. Deborah Schenberger’s biomechanics research lab at the University of Portland in Portland, OR. She has designed some experiments to look at issues related to barefoot running, a running trend popularized by Christopher McDougall’s book Born to Run. Without the padding provided by traditional running shoes, barefoot runners minimize their heel strike,…

John Melville, our Biology Staff Scientist, has developed an innovative way to demonstrate how the electrical and physical events of the cardiac cycle are related using a Blood Pressure Sensor (BPS-BTA $105) and an EKG Sensor (EKG-BTA $147) with our award-winning Logger Pro software. EKG with Blood Pressure Pulse Blood pressure is a measure of the changing fluid pressure within the…

Our biology staff scientist, John Melville, has been working with our new LabQuest Mini and has found a way to integrate video analysis into a simple muscle physiology experiment. EKG sensors are attached to the bicep and forearm muscles to record muscle activity. A Low-g Accelerometer is then attached to the wrist to measure joint…

If you have ever wanted to introduce your students to the study of human biomechanics, we have found a great product for you. While attending the Annual Meeting of the Human Anatomy and Physiology Society (HAPS), we came across two excellent interactive models that use Vernier sensors and our LabQuest to study human biomechanics. The…

LabQuest App v.1.2 includes a separate application called the Audio Function Generator. This application generates audio signals through the LabQuest internal speaker or through external stereo speakers. To start the application, tap the Home icon in the tool bar and then select Audio Function Generator. Explore the relationship between frequency and pitch either with the…

Dr. John Melville, our Director of Biology, developed an innovative diving reflex laboratory exercise while teaching at Wartburg College. In the lab, students learn basic heart anatomy, histology of arteries and veins, and perform an EKG using Vernier sensors. The students then develop their own experiment, which often involved the diving reflex. Weddell Seal The…
