What Goes On Inside a Spectrophotometer?
A spectrophotometer is an analytical instrument used to measure the amount of light absorbed (or transmitted) as it passes through a sample, such as a solution containing food dye. Spectrophotometers work on a few basic principles: The intensity of color is a measure of the amount of dissolved material in solution. For instance, imagine 2 solutions […]
Smartphones in High School Science Classes
Smartphones are everywhere today, especially for teenagers, and their potential extends far beyond social media and texting. In high school science classrooms, smart- phones and related devices offer a plethora of opportunities to enhance learning, engage students, and facilitate a deeper understanding of scientific concepts across science disciplines. Here’s how and why smartphones can be […]
Teach Spectroscopy with the Carolina® Spectroscopy Chamber
Do you have a large, bulky spectrophotometer sitting on a shelf or in a cabinet collecting dust? Do you use it for only one or two labs a year? It’s an expensive, sensitive instrument. Even the cuvettes are expensive and delicate. Ensuring all your students use them for data collection may make you cringe and […]

Substances with a Hazardous Nature but May Have Potential Educational Utility
These chemicals should be removed from the schools if alternatives can be used. For those that must be retained, amounts should be kept to a minimum. These are appropriate for advanced-level High School classes only. This following list was generated from the Manual of Safety and Health Hazards in the School Science Laboratory published by […]
Carolina: Here to Help with Assistive and Adaptive Technologies for Your Science Classroom
Assistive and adaptive technologies are designed to support students, including those with disabilities, in their educational pursuits. These technologies aim to enhance learning experiences, provide equal opportunities, and foster independence. Assistive and adaptive technologies are particularly important in the science classroom given the hands-on, laboratory component of science classes. Â Here are a few examples […]
Serial Dilution
A serial dilution is a laboratory technique used to create a series of solutions from an initial stock solution. They can be used to prepare a standard curve or to reduce the concentration of a sample to a manageable level while still being able to calculate the original concentration. A serial dilution can also create […]
Dimensional Analysis
Dimensional analysis might sound like an intimidating scientific term, but it’s a powerful tool that helps us make sense of the world around us. Dimensional analysis can be used to solve a wide range of problems in a variety of disciplines, from chemistry and physics to cooking and construction. It is a technique used to […]
