Innovative Uses of Vernier Technology

Investigating Intermolecular Forces Using the Mini GC Plus

Chromatogram of an equimolar ethanol and n-butanol mixture Taking full advantage of the , Mr. William Patrick Cunningham, from Claudia Taylor Johnson High School in San Antonio, Texas, designed an innovative experiment in which students study intermolecular forces. The experiment uses different alcohols to demonstrate how variations in molecular structure and molecular mass affect the…

Design-It-Clean Challenge

Ms. Alejandra Guzman, a Secondary Science Strategist for Los Fresnos CISD in Texas, shared her recent experience with Project Based Learning (PBL) in the Design-It-Clean Challenge. In this dynamic end-of-year project, students are challenged to create a water filtration device that is efficient, affordable, and sustainable. Students also create websites and marketing materials in order…

Evolution of Aquatic Respiratory Systems

Experiments in comparative physiology are an excellent way to teach concepts in evolutionary biology. In the Fall 2017 edition of The Caliper, we published a well-received, college-level comparative physiology experiment using scorpions and cockroaches. In response to the many requests we received for a high-school-level activity, the Vernier Biology Department put their heads together and…

Mobile Teaching Laboratory Provides Inspiration Using Vernier Products

William H. Roden, senior scientist, and Dr. Amanda L. Jones, Director of the Science Education Department at Seattle Children’s hospital, have developed several innovative ways to incorporate Vernier technology into their teaching modules. The modules are designed for grades 4–12 and cover a variety of topics including biotechnology, microscopy, human physiology, and neuroscience. Vernier sensors…

Potentiometric Titration of Aqueous Iodine

Redox titration of iodine in povidone iodine using thiosulfate In an iodine redox titration, starch, which turns blue-black in the presence of iodine, is typically used as the indicator. However, this method can be challenging for students because of the low solubility of iodine in water and the pH dependence of the reaction (which proceeds…

An Inquiry Approach to Understanding the Relationship Between Dissolved Oxygen and Temperature

Image credit: Roland P. Stout, Univ. of North Carolina at Pembroke By Roland P. Stout, PhD, Univ. of North Carolina at Pembroke For several semesters I have had my freshman chemistry students monitor our campus water feature on a weekly basis using most of the Water Quality Index measurements. The water feature is an artificial…

Identifying Mercury in Fluorescent Light Bulbs

Doug Balmer, a chemistry teacher from Warwick High School in Lititz, Pennsylvania, designed a lab experiment for his students that investigates the absorption and emission of light using a spectrophotometer. The experiment, entitled “Light Lab: Studying Light and Electrons,” is divided into four parts: understanding how a spectrophotometer works, seeing the connection between wavelength and…

An Inexpensive Beta Radiation Spectrometer

When studying radioactivity, most students have heard that the consequences include everything from Godzilla to spider senses. But few students know we can safely measure the energy of radiation and study something called nuclear spectroscopy in an ordinary science lab. A beta radiation spectrometer can be built from a Vernier Radiation Monitor, a couple of…

Amusement Park “Round Up”

Chris Murray, of Tualatin High School in Tualatin, Oregon, recently sent us some great data taken with LabQuest and a Low-g Accelerometer on an amusement park ride, called Zero Gravity (also known as Round Up). As the ride began, a student held the accelerometer at chest level, pointed horizontally. When the motion started, two things…
