Voluntary Recall on the Vernier Circuit Board 2

Vernier Circuit Board 2

Due to potential safety concerns, Vernier is conducting a voluntary recall of the Vernier Circuit Board 2 (order code VCB2). The issue is that it is possible to place the switch between two positions. When this happens, the power can short circuit and overheat the switch to dangerous temperatures. While no injuries have been reported, this affects Vernier Circuit Board 2 units that were purchased between August 2015 and April 2018.

Those who own one or more Vernier Circuit Board 2 units need to:

  1. Stop using the Vernier Circuit Board 2 immediately.
  2. Remove all batteries from the battery holders immediately.
  3. Arrange for a retrofit of the circuit board to eliminate this problem by providing your information in the Vernier recall form.

Once the recall form is filled out, Vernier will send the customer a prepaid UPS label to return the unit(s) for a free upgrade.

This recall was conducted, voluntarily by Vernier, under the Consumer Protection Safety Commission’s Fast Track Recall process. Fast Track recalls are initiated by firms who commit to work with CPSC to quickly announce the recall and remedy to protect consumers.

Coding with mBot: Self-Driving Vehicles Module

The topic of self-driving vehicles is one that combines diverse issues ranging from engineering to federal regulations. While it may be years before you have a self-driving car in your driveway, you can use mBot in your classroom today! Equipped with ultrasonic distance, line-following, and light-level sensors, mBot is an affordable, easy-to-program robot designed to bring coding and computer science education into the real world. With our new Coding with mBot: Self-Driving Vehicles module, a set of nine guided coding activities that build upon each other, you and your students can successfully learn to program mBot to mimic many self-driving car actions.

In Coding with mBot: Self-Driving Vehicles, students write programs to make mBot perform activities such as following a line, avoiding an obstacle, and parallel parking. Along the way students learn basic coding and troubleshooting skills. The activities are aligned with the Computer Science Teachers Association’s K-12 Computer Science Standards, and require only an mBot, the free mBlock software (based on the popular block-based programming language Scratch), and some patience for the occasional traffic jam.

In the first activity “Driving mBot,” students are introduced to mBlock software and write a program that allows them to control mBot’s movement in four directions, make sound with mBot’s buzzer, and turn on the built-in LEDs. Teaching tips and example programs in the accompanying Instructor Information support you as you facilitate student learning.

Download Activity 1, “Driving mBot,” as a free preview at

Coding with mBot: Self-Driving Vehicles will be available soon as an electronic download and is included free with your purchase of one or more mBots from Vernier. If you already own mBot, you can purchase Coding with mBot: Self-Driving Vehicles separately (order code: MBOT-MSDV-E).

At the heart of mBot is the mCore, a microcontroller based on the Arduino Uno. In addition to the ultrasonic, line-following, and list-level sensors packaged with mBot, mCore has four RJ25 sensor ports, two motor ports, two RGB LEDs, a buzzer, and an IR transmitter/receiver. Students make use of all of those features while programming mBot to act as an autonomous vehicle. For instance, set up the RGB LEDs to work as turn signals. In addition, to help keep mBot on its track, the line-following sensor can serve as a trigger for a car alarm. mCore’s IR transmitter and receiver allow messages to be passed between mBots, making it possible to coordinate their motion and stop them from colliding.

The activities in Coding with mBot: Self-Driving Vehicles can be completed using the free mBlock app (iOS/Android) or with the more advanced mBlock software (Windows/macOS/ChromeOS). More experienced students can work even their way through the activities using the Arduino IDE.

Everyone from Google to GM® is interested in self-driving cars today. Bring that enthusiasm into the classroom with mBot and the activities in Coding with mBot: Self-Driving Vehicles. Learn more at

Follow-Up on The Great American Eclipse

Light and UV data taken during totality in Oregon
Data taken during totality in Oregon

We enjoyed the eclipse and were pleased that so many people sent us great data collected during the event. Leading up to the eclipse, we encouraged science teachers to experience the eclipse from the path of totality, using the slogan, “The difference between a total eclipse and a partial eclipse is night and day.” Our employees were even given the day off to travel to the path of totality, as our office was only at 99 percent totality. We distributed and sold tens of thousands of eclipse glasses to ensure people could safely view the eclipse. In our previous newsletter (published just before the eclipse) we asked teachers to record and share with us data on the physical parameters (light level, UV intensity, temperature, etc.) observed during the eclipse.

Vernier helped sponsor a project to reproduce the Eddington experiment, which was an important verification of Einstein’s theory of general relativity. This group was headed up by Toby Dittrich, of Portland Community College, in Portland, Oregon. While the preliminary results of this experiment are promising, the final analysis is not yet complete, and we will provide further follow up in a later newsletter.

As part of this experiment, here is a photo with several overlapping exposures of different lengths. It includes marks around stars that are visible near the sun. The bending of light waves is what the Eddington experiment measured and can be seen in the very tiny changes in the positions of these stars.

Erasing the Glow in the Dark: Controlling the Trap and Release of Electrons in Phosphorescent Materials

William A. Getz, Dannielle A. Wentzel, Max J. Palmer, and Dean J. Campbell; J. Chem. Educ., 2018, 95 (2), pp 295–299.

The authors use fluorescence spectroscopy to demonstrate the darkening effect using lower energy wavelengths on the intensity of the fluorescent light and the time until the emission is quenched. A zinc sulfide phosphor doped with Cu metal is excited by a 405 nm LED, and the fluorescence spectrum is observed. In a second trial, after the excitation, a 650 nm red laser light is shined on the phosphor. The intensity of the fluorescence spectrum is diminished and the length of time that the light is emitted is reduced. Connections to understanding how electrons move from the valence band to the conduction band and back are made in the article. It also discusses the kinetics of the changes observed as they relate to temperature and activation energy. A Vernier SpectroVis Plus spectrophotometer and Optical Fiber were used to observe the spectra produced.

Adapting Three Classic Demonstrations To Teach Radiant Energy Trapping and Transfer As Related to the Greenhouse Effect

Dwayne A. Bell and Jesse C. Marcum; J. Chem. Educ., Articles ASAP (As Soon As Publishable).

The authors address three fundamental concepts that are part of students’ understanding of the greenhouse effect and global climate change; the existence of infrared radiation, absorption of IR by greenhouse gases, and steady-state energy flow.

To demonstrate the existence of infrared radiation, the authors used a Pyranometer to measure the level of irradiance at one centimeter increments along a rainbow spectrum they produced from a 300 W theatrical light. They were able to show that there was energy being produced from the light bulb, even though the pyranometer was placed in a part of the spectrum that appears black to the naked eye.

The authors also discuss their demonstrations of how carbon dioxide molecules are energetically excited and vibrate in the presence of infrared light by using models of the molecules constructed from balls and springs. They also model how energy flows through a system using a plastic water-flow device with changeable partitions to mimic the addition or removal of carbon dioxide from the atmosphere.

Demonstrations of Magnetism and Oxidation by Combustion of Iron Supplement Tablets

Max J. Palmer, Keri A. Martinez, Mayuresh G. Gadgil, and Dean J. Campbell; J. Chem. Educ., 2018, 95 (3), pp 423-427.

The authors demonstrate the conversion of iron(II) ion in iron nutrient supplements to hematite by first heating a sample with a torch. They compare the products of heating a supplement to those produced by heating iron(II) sulfate heptahydrate. The second compound produces magnetite and maghemite, which have a stronger attraction to a magnet than hematite. The strength of the magnetic fields is measured and compared using a Magnetic Field Sensor and LabQuest 2.

Nanoparticle Synthesis, Characterization, and Ecotoxicity: A Research-Based Set of Laboratory Experiments for a General Chemistry Course

Zoe N. Amaris, Daniel N. Freitas, Karen Mac, Kyle T. Gerner, Catherine Nameth, and Korin E. Wheeler; J. Chem. Educ., 2017, 94 (12), pp 1939–1945.

Students learn to synthesis silver nanoparticles and then characterize them using UV-VIS spectroscopy and dynamic light scattering. The particles are easily synthesized with readily available reagents. To measure the spectrophotometric properties, the students used a Vernier UV-VIS Spectrophotometer. Green chemistry principles are followed during the course of this experiment.

Speciation and Determination of Low Concentration of Iron in Beer Samples by Cloud Point Extraction

Lida Khalafi, Pamela Doolittle, and John Wright; J. Chem. Educ., 2018, 95 (3), pp 463-467.

Students determine the concentration of iron in beer samples. They learn how to extract the iron and then complex it so that the concentration can be determined using the Beer-Lambert relationship. They set up standards and use absorbance spectroscopy to determine the concentration of iron in the original beer sample. Vernier SpectroVis Plus Spectrophotometers were used in this experiment.

Determining the Speed of Sound and Heat Capacity Ratios of Gases by Acoustic Interferometry

Thomas D. Varberg, Bradley W. Pearlman, Ian A. Wyse, Samuel P. Gleason, Dalir H. P. Kellett, and Kenneth L. Moffett; J. Chem. Educ., 2017, 94 (12), 1995–1998.

The authors describe a method to determine the speed of sound and heat capacity through various gases. They use a microphone and white noise apparatus connected to a sound cavity, which is a long, plastic tube. The data is collected and analyzed on an Apple iPad. They refer to work done in this same area by others using Vernier LabPro and LabQuest 2.

Because the tube has a fixed length, when the white noise is introduced into the tube, an interference pattern is generated and plotted. Students can apply a Fourier transform to determine the frequency spectrum of the standing waves in the tube.

Studying Intermolecular Forces with a Dual Gas Chromatography and Boiling Point Investigation

William Patrick Cunningham, Ian Xia, Kaitlyn Wickline, Eric Ivan Garcia Huitron, and Jun Heo; J. Chem. Educ., 2018, 95 (2), pp 300–304.

The authors describe two laboratory experiences they have developed for their students to study the difference in structure and intermolecular forces between n-butanol and ethanol. Students measure and plot the boiling temperature of ethanol, n-butanol, and an equimolar mixture. They also compare the behavior of each compound and the mixture as they pass through a gas chromatograph. The goal is to try to understand how the intermolecular forces between the compounds affect their properties. They also attempt to understand the differences in the shapes of the chromatograms as the individual compounds and mixture pass through the column in the gas chromatograph. For these activities the students used a Vernier Mini GC Plus Gas Chromatograph, temperature probes, and Logger Pro 3 software on a computer.

Open-Source Low-Cost Wireless Potentiometric Instrument for pH Determination Experiments

Hao Jin, Yiheng Qin, Si Pan, Arif U. Alam, Shurong Dong, Raja Ghosh, and M. Jamal Deen; J. Chem. Educ., 2018, 95 (2), 326–330.

The authors describe how to build a low cost pH probe from readily available, off-the-shelf parts. Their system uses an Arduino® board to process the data from a glass pH electrode. They also incorporate a temperature sensor and Bluetooth® wireless technology. They program their system using the Arduino Sketch programing language. The authors hope that by building this system their students will better understand how a pH meter works. A Go!Link and Voltage Probe were used to measure the voltage produced by the glass pH electrode.

Quantifying Sucralose in a Water-Treatment Wetlands: Service-Learning in the Analytical Chemistry Laboratory

Emily C. Heider, Domenic Valenti, Ruth L. Long, Amel Garbou, Matthew Rex, and James K. Harper; J. Chem. Educ., Articles ASAP (As Soon As Publishable).

As part of a service learning approach to increasing community engagement, students perform analytical chemical tests of wetlands to determine pH, chloride, total dissolved solids, and phosphorus. Since Sucralose has been determined to be a indicator of anthropogenic waste in natural waters, students also test for this artificial sweetener. A Conductivity Probe was used to determine total dissolved solids. Students measure the conductivity of the samples in µS/cm and then converted this value to ppm.
