In celebration of Earth Day, we held our annual “Swap It,” where employees swapped used books, shirts, and videos with each other. A recycling bin was provided for old tennis shoes, and everyone brought healthy snacks for the afternoon.
We also worked with SOLV to pick up trash and debris around Beaverton Creek. Dave Vernier and Jim McBride took a LabQuest with the Vernier GPS sensor to collect the location of the trees Vernier planted in Beaverton Creek a few years ago.

In the latest edition of The Caliper, we take a LabQuest to Antarctica, investigate spectroscopy at a grocery store, and study the diving reflex! Read it online or join our mailing list to have The Caliper delivered to your school or e-mail inbox twice a year.
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. With this setup, you might want to explore the hearing response of your students. What is the lowest frequency that your students can hear? What about the highest frequency?
John Melville, one of our Biology Staff Scientists, 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.
The hoop spring bumpers in the Bumper and Launcher Kit are excellent examples of Hookean devices. To investigate Hooke’s law, we’ll use the Bumper and Launcher Kit, Dual-Range Force Sensor, Vernier Dynamics System, and Motion Detector to determine how the length of the hoop spring is proportional to the force applied.
Have you ever noticed that the bananas you bought look different in the store than they do when you get them home? This is because not all lights used in grocery display cases are the same. The main reason for having different lighting is to improve shelf life of perishable products. Nevertheless, you can be sure some research has gone into determining the best light to entice you to make a purchase.
Recently, a few of us at Vernier drove from our office in Beaverton, OR to Seattle, WA for a conference. We attached a Vernier GPS Sensor to a LabQuest and collected data throughout the trip. LabQuest not only records the latitude and longitude of each point, but the speed, direction, and altitude, as well.
By its name alone, LabQuest seems destined for adventure. When I decided to go on a National Geographic Expedition to Antarctica in January, there was no doubt in my mind that I would be taking mine with me. Sailing from Ushuaia, Argentina, we spent almost two days crossing the infamous Drake Passage.
The new Vernier Power Amplifier allows your students to drive a variety of devices, including speakers, lamps, small DC motors and RLC circuits. The Power Amplifier delivers ± 10 V and currents up to 1 A. It works with any waveform, including DC, sine, square, triangle and sawtooth.
Now when you collect sensor data around the globe with LabQuest or a computer, your students
can record their exact latitude, longitude, and altitude. Vernier’s new GPS Sensor is as small as your
thumb, and is affordably priced for school budgets.
