High CO2 Levels Putting You to Sleep?
Roland Stout, Associate Professor of Chemistry at the University of North Carolina at Pembroke, challenged his environmental chemistry class to find an interesting and environmentally significant carbon dioxide source or sink and to verify their findings using a CO2 sensor.

Drop Counter as Fraction Collector
Although the Drop Counter was developed to record drops during titration, attaching the Luer-lock stopcock to the outlet of a chromatography column adapts it for use as an inexpensive fraction collector for column chromatography.
Force Plate Used to Test Wing Spar
Ron Bowerman knows how to motivate students—competition. In his physics class, students compete for a simulated high stakes contract with an airline. Physics and engineering skills are put to the test as students work in engineering teams that try to design the lightest and strongest wing spar for an airplane.
Balloon Launch Uses Vernier Technology
The FIRST LEGO® League Team from Reston, VA recently took part in the High Altitude LEGO Extravaganza (HALE) balloon launch. Their payload included a LEGO NXT Robotics System with a Vernier NXT Adapter and two Vernier sensors—a UVB Sensor and a Surface Temperature Sensor.

Studying Acceleration at Amusement Parks
Richard DeLombard of NASA’s Glenn Research Center in Cleveland has come up with a unique way to get students to analyze acceleration graphs from amusement park rides.

Anscombe’s Quartet
Have you ever wondered about how much outlier points influence the curve fits you do in software like Logger Pro? Or, how much you can rely on measures like the slope uncertainty or the correlation coefficient as a judge of how good a line fits your data?
Vernier Used Around the GLOBE
Is the heat given off by 500 people enough to change the temperature inside a large auditorium? How does the temperature and salinity of a tide pool compare to that of the nearby ocean water? These were just two of the questions posed to about 250 students from 52 countries who gathered in Cape Town, South Africa, this summer for the GLOBE Learning Expedition (GLE). And of course, Vernier equipment was used to investigate the answers to those questions.
Activities for Vernier Solar Power
From our solar dashboard, you can see a live camera view of the roof solar panels, our weather station data, and a live display of the power production of the panels. There are also tables and graphs you can use to investigate the energy production of the panels over time. It is our hope that you will be able to use this information to facilitate the study of solar energy production with your students.
You can download the background information, complete with data and sample questions from our Solar Dashboard »
Measuring Motor Speed
Brian Lamore, physics teacher at the Chinquapin School, Highlands, Texas, has his students build a “Beakman’s” Motor to study electromagnetic induction. This simple motor can be built in a single class period and the activity is always a favorite of his students. But nothing makes an activity more interesting than a little competition, so Brian challenges his students to build the motor that will spin the fastest.
Spectral Analysis of Fireflies
10 year-old Ben Carter of Nashville, Tennessee, was curious about the light given off by a firefly. Ben has inherited his natural curiosity and love of science from his father, Vernier consultant David Carter. Ben borrowed his dad’s Vernier Spectrometer and used it to capture the emission spectra of the fireflies.
