Investigate the transmissive and reflective characteristics of infrared light as compared to visible and ultraviolet light.
A person holding a piece of clear acrylic between the FLIR ONE™ camera and herself, blocking infrared light on the left sid...
The sense of balance is complex since it combines sensory input from the eyes, inner ear, and stretch receptors located in the tendons and muscles. In the classroom, you can demonstrate that visual input is important for balance. Try balancing on on...

Perform our “Absorption of Radiant Energy” experiment using the FLIR ONE™ thermal camera and the Thermal Analysis app. Use a desk lamp and an incandescent lig...
Chemistry students study Havasu Creek in the Grand Canyon.
In July, students in Alex Canale’s chemistry class at Saint Peter's Preparatory School in New Jersey took LabQuest on a ten-day adventure to the Grand Canyon to investigate the wate...
Many parts of the country experienced extremely hot and dry weather this past summer. One effect of this was increased electricity demand for air conditioning in houses and places of business. An air conditioner works by compressing a refrigerant ga...

Long ago, when I was a high school chemistry teacher, my students ran a forensics experiment using a Spectronic 20 spectrophotometer. The students measured the absorbance spectra of food dyes in various sports drinks to determine whi...
Inquiry experiments can be designed to be carried out using everyday household items. In this experiment, students use common beverages to investigate the relationship between conductivity and electrolyte levels. The experiment uses a Conductivity P...
How often do you breathe in and out? Most of the time, we do not think about breathing, and don’t notice we are doing it. In this experiment, you will determine your respiration rate by examining the temperature of the air at your nostrils using t...
One of the most disappointing things for a teacher is not being able to provide evidence for a claim that students find difficult to accept. When students ask how it is possible to know that CaCl2 produces three ions, while NaNO3 produces only two, ...
