There are so many powerful features available in our Logger Pro software, it is easy to miss one. One such feature is the ability to display vectors using an Animated Display meter. Data from accelerometers, force sensors, and motion detectors are perfect for creating a 2-D animated vector display. You can even display an animated vector right on a video used in video analysis.
In late October 2005, employees from Vernier participated in a tree planting event in conjunction with the organization Friends of Trees. We planted 200 trees in the wetlands area surrounding nearby Beaverton Creek. As part of the 2009 Earth Day activities, David Vernier and Jim McBride checked on the trees. They used a LabQuest and our Vernier GPS Sensor to note the position and type of each surviving tree.
Integrated-Science students Erin Smyers and Nicole Loughner from Homer-Center High School in Homer City, PA, worked with their science team leader, Mark Shopland, to investigate the pH changes in an oxidation-reduction reaction. The students chose to work with Thionin based on the demonstration “Thionin – The Two-Faced Solution” published by Flinn Scientific Inc. (Publication No. 0815.00).
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.
As part of Project Lead The Way engineering courses, Ken Kessenich at Pius XI High School in Milwaukee, WI started teaching a new unit that involves simple machines. He wanted his student to see REAL problems instead of simulations to demonstrate effort force and mechanical advantage.
