The original Vernier Circuit Board has been updated to include more components and to provide more versatility for basic circuit experiments. While the footprint of the Vernier Circuit Board 2 has the same dimensions as the original version (10 in. × 6.5 in. [25.5 cm × 16.5 cm]), the new board packs more experimental options into the space.
Photochemical reactions are very important in many areas of chemistry. These reactions often proceed quickly and, as a result, require fast reaction techniques to analyze. The Vernier Flash Photolysis Spectrometer is a simple, user-friendly instrument for demonstrating to undergraduate chemistry students the fundamental principles of these types of reactions.
Using Conductivity Measurements To Determine the Identities and Concentrations of Unknown Acids: An Inquiry Laboratory Experiment
K. Christopher Smith and Ariana Garza, J. Chem. Educ., Article ASAP (As Soon As Publishable), Publication Date (Web): May 8, 2015
This article describes a student-designed titration experiment that uses LabQuest and a Conductivity Probe to identify unknown acids as being either HCl or H2SO4 and to determine the concentrations of the acids. Using an inquiry context, students gain experience with titrations, conductivity, procedural design, and analysis of results. The experiment is suitable for advanced high school or college-level general chemistry students.
Decay Kinetics of UV-Sensitive Materials: An Introductory Chemistry Experiment
Garrhett Via, Chelsey Williams, Raymond Dudek, and John Dudek, J. Chem. Educ. 2015, 92, 747–751
A procedure that provides an innovative approach to undergraduate chemistry kinetics experiments is described in this article. Logger Pro and a SpectroVis Plus Spectrophotometer with the SpectroVis Optical Fiber are used to measure the reflection spectrum from an incandescent bulb off of a UV-sensitive bead or thread, both in its excited state (immediately after UV irradiation) and unexcited state (only incandescent illumination). First-order kinetic decay rates are obtained by measuring the time- dependent reflection spectra of ultraviolet sensitive objects as they return from their excited, colored state back to their ground, colorless state.
Demonstrations of Frequency/Energy Relationships Using LEDs
Graham T. Cheek, J. Chem. Educ. 2015, 92, 1049–1052
In this article, the use of LEDs (light-emitting diodes) to demonstrate the relationship between frequency (or wavelength) and semiconductor energy level differences is described. LEDs can function as light detectors, and this ability is exploited to show the minimum light frequency needed to produce a voltage response in an LED. The light sources can be other LEDs or a flashlight with colored filters. A SpectroVis Plus Spectrophotometer with a SpectroVis Optical Fiber was used to measure visible LED wavelengths when nominal values were not available.
Boiling Water Demo: Much More than Meets the Eye
Jean Weaver, Chem13 News, 2015, 415, 8–9
This article presents a demonstration to help students understand what happens at the microscopic level when water warms and boils. The setup uses Logger Pro and a Stainless Steel Temperature Probe to monitor the temperature of a beaker of water heated by a hot plate. The author explains how the activity allowed students to think critically about the relationship between kinetic energy, potential energy, heat, and temperature.
Using Research-Based Interactive Video Vignettes to Enhance Out-of-Class Learning in Introductory Physics
Priscilla W. Laws, Maxine C. Willis, David P. Jackson (Dickinson College), Kathleen Koenig (University of Cincinnati), and Robert Teese (Rochester Institute of Technology), The Physics Teacher, v53, #2 (Feb 2015), 114–117.
The authors explain how to use a series of short videos to enhance a physics class. The vignettes are based on physics education research and are distributed as free open-source software.
Light-Emitting Diodes: Solving Complex Problems
Gorazd Planinšicˇ (University of Ljubljana and The House of Experiments, Slovenia) and Eugenia Etkina (Rutgers University), The Physics Teacher, v53, #5 (May 2015), 291–297.
This is the fourth in a series of articles by the authors on LEDs. The series, all of which can be found in The Physics Teacher, is a complete collection of uses for LEDs in physics teaching.
As summer comes to an end, many of you are getting ready for the fun and excitement of starting a new school year. For your fall planning, we have ten tips to ensure that integrating Vernier technology into your labs is easy and stress free. Have a great school year!
1. Keep your software up to date with a Vernier web account.
If your school owns Logger Pro 3 or LabQuest Viewer for Windows or Mac, you can create a free Vernier web account and easily download the latest version at any time. You can also use your Vernier account to directly distribute Logger Pro to your students. Keeping your software updated will help ensure that your technology is ready for the laboratory when your students are. Sign Up or Create an Account
2. Update and charge your LabQuests before class begins.
As you prepare your lab for the school year, update your LabQuests to receive new features and enhancements. We also recommend that you charge your LabQuests for a full eight hours before using them for the first time in the school year. Update Your LabQuests
3. Collect data using our free Graphical Analysis app for iOS®, Chrome™, and Android™.
