The PhET project at the University of Colorado creates "fun, interactive, research-based simulations of physical phenomena." This particular one deals with Beer's Law. "The thicker the glass, the darker the brew, the less the light that passes through." Make colorful concentrated and dilute solutions and explore how much light they absorb and transmit using a virtual spectrophotometer! The simulation is also paired with a teachers' guide and related resources from PhET. The simulation is also available in multiple languages.

Chemists are often interested in how fast a reaction will occur, and what we can do to control the rate. The study of reaction rates is called kinetics, and we will learn about average reaction rate, rate laws, the Arrhenius equation, reaction mechanisms, catalysts, and spectrophotometry.

Chemical kinetics and buffers are two topics that are extremely difficult for students to understand. Combining the two topics will allow for a staggered, repetitive approach to teaching students to understand of how these two topics in chemistry actually work. Students will both qualitatively and quantitatively track the effect and enzyme has on a reaction, calculate the reaction rate and buffer capacity. Students will use a variety of lab techniques including calculations using Beers Law and spectrophotometry.

We are all well aware of the composition of the world -atoms form molecules, compound become more complex, and the organization of these atoms into materials with unique structures is what brings about life. As scientists though, we must study these substances , which presents a challenge. How do we study something so incredibly small? One of the simplest methods is spectrophotometry. Different molecules will interact with light in different ways. By studying this, we can quantitatively say both how much light a compound absorbs as well as what kind of light. Certain functional groups tend to absorb light at certain wavelengths, giving "peaks" to the spectrum of light absorption. This lab demonstrates basic principles of absorbance, measured using spectrophotometers.
