Why Teach the Melting Point of Organic Compounds?
At my school Archbishop Hoban High School in Akron, Ohio, I teach a semester of organic chemistry as an advanced science elective. Students who choose this course learn about carbon-based compounds, from alkanes to arenes, and use a range of Vernier instruments, from melt stations to mini gas chromatographs. Taking this class not only gives my students more opportunities to hone their lab skills, but it also helps them to develop their understanding of organic compound behavior and physical properties of matter.
One key concept we explore in this class is the melting points of organic compounds. This lesson can easily fit within a chemistry unit on covalent compounds or intermolecular forces—it’s also a valuable lesson to include in AP chemistry courses when covering the properties of substances and mixtures (Unit 3). Investigating this physical property can help students understand how materials are characterized by measurable properties, how molecular forces influence those properties, and why materials with different properties are better suited to different practical uses. In particular, melting points are useful for making predictions about the purity of a substance and about the identification of an unknown compound.

Why Use Two Probes When You Only Need One?
Vernier helps you keep experiments simple. Using our multi-channel Go Direct® Optical Dissolved Oxygen Probe, students can simultaneously measure dissolved oxygen concentration (mg/L), percent saturation (%), and water temperature. Students normally need to use both a dissolved oxygen probe and a temperature probe to learn how the dissolved oxygen content of water depends on the water temperature. This is an important ecological concept, as some organisms, such as salmon, require high concentrations of dissolved oxygen in their water. Your students no longer need an additional probe to measure temperature when they use a Go Direct Optical Dissolved Oxygen Probe.

What Are the Best Light Sources For Photosynthesis?
Photosynthetic organisms such as plants and algae use electromagnetic radiation from the visible spectrum to drive the synthesis of sugar molecules. Special pigments in chloroplasts of plant cells absorb the energy of certain wavelengths of light, causing a molecular chain reaction known as the light-dependent reactions of photosynthesis. The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges. In this study, we used a Go Direct® SpectroVis® Plus Spectrophotometer with a Vernier Spectrophotometer Optical Fiber and LabQuest 2 to collect spectra from four different light sources. This allowed us to determine the wavelengths emitted by each source and to get an idea of their relative intensities.
