Teaching the Nature of Light: New Ways to Demonstrate Interference and Diffraction

During the 17th century, there were two competing models to describe the nature of light. Isaac Newton believed that light was composed of particles, whereas Christopher Huygens viewed light as a series of waves. Because Newton observed straight-line paths of light, he concluded that light could not be wave-like. Thomas Young’s double-slit experiment in the…

Use Go Direct Sensors and VPython for Data-Rich Computational Physics Activities

During most lessons about projectile motion, students inevitably ask, “What about air resistance?” The typical, albeit unsatisfying, response usually suggests that a lot of math is required. It’s a laborious process that few students are willing to work through by hand, but it’s a great task to hand off to a computer! Indeed, many instructors…

Conductometric Titration: An Alternative to Gravimetric Analysis

Gravimetric analysis is a classic technique for determining the mass of an analyte through precipitation. Because of the complex nature of gravimetric analysis, it can be a challenging experiment. In an article published in the Journal of Chemical Education, Jennifer Garcia and Linda Shultz compare a conductometric titration to conventional gravimetric analysis and conclude that…

Explore Vitamins with New Features of Spectral Analysis

Vitamin B2, also known as riboflavin, was first isolated in 1933. It is an essential nutrient for humans as the precursor of the coenzymes flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). FAD plays a key role in several important enzymatic reactions in metabolism, including the Krebs cycle. Riboflavin also happens to be a relatively…

Celebrating Darwin Day with Vernier Technology

February 12th is Darwin Day, and Darwin’s theory of evolution is one of the central concepts in biology. Experiments in comparative physiology are an excellent way to teach concepts in evolutionary biology. The Vernier Biology Department developed an experiment that investigates the comparative physiology of snails and fish. A comparison of the respiration rates of…

The Terminal Velocity of a Snowflake

During a recent snowfall, Richard Born, a retired associate professor from Northern Illinois University, captured a slo-mo video (240 frames/s) of falling snowflakes using his iPhone® X. The camera was approximately a foot in front of a wooden fence to serve as a background for the falling snow. I’m sorry; your browser doesn’t support HTML5…

Modeling Planetary Transits Using a Light Sensor

Experiment setup for identifying planetary transits with a Vernier Light Sensor Maya Falck, Scott Godsen, and Rebeca Waysek, teachers at The Spence School in New York City, New York, were inspired by an activity developed through NASA’s Kepler Space Telescope site that demonstrates the technique of using planetary transits to identify new exoplanets. The teachers…

Study Photosynthesis and Respiration with Bio-Rad® Algae Beads and Go Direct® SpectroVis® Plus Spectrophotometer

Algae beads, along with the , provide a great way to study photosynthesis and respiration. Algae beads consist of freshwater algal cells suspended in sodium alginate and hardened in calcium chloride solution. In this suspension, the algal cells can still undergo cellular respiration and photosynthesis, exchanging gases with the liquid around them. Traditionally, a CO2…

Discover the Wavelength

Many schools can’t afford a classroom set of spectrophotometers. So how can you use a single spectrophotometer and a class set of colorimeters to have your students discover the best wavelength of light to use in an experiment? For Beer’s law and kinetics experiments, students must choose a specific wavelength to conduct the experiment. Students…
