This set of student labs are designed to allow anyone to recreate simple experiments at home to explore electronics and Electrical Engineering concepts. The software and hardware utilized are LabVIEW and NI Low Cost USB data acquisition devices.
This animation is a mosaic of cloud cover data taken by several different satellites in the infrared band. One of the most prominent cloud features during this time was Hurricane Erin near the Atlantic coast of the United States.
How do greenhouse gases affect the climate? Explore the atmosphere during the ice age and today. What happens when you add clouds? Change the greenhouse gas concentration and see how the temperature changes. Then compare to the effect of glass panes. Zoom in and see how light interacts with molecules. Do all atmospheric gases contribute to the greenhouse effect?

Infrared signals are commonly used to transmit information between phototransmitters and photoreceivers. In this lab, a photodiode and Low Cost National Instruments USB DAQ are used to detect the presence of an infrared signal. The IR Remote Control lab is designed as a labratory or at-home experiment.
examines infrared light, how it was discovered, infrared astronomy, atmospheric windows, and more. An infrared astronomy timeline is included, along with links to news and discoveries, images, and classroom activities.
This animation is a mosaic of cloud cover data taken by several different satellites in the infrared band. Instead of showing a global composite, it is cropped to highlight the Atlantic Ocean. One of the most prominent cloud features during this time was Hurricane Erin.
How would your world look if you saw heat instead of light? In this interactive resource produced for Teachers' Domain, see what familiar objects look like through an infrared camera and watch infrared videos of geysers, mudpots, and hot springs.
In this video segment adapted from NASA, astronomer Michelle Thaller introduces the world of infrared light and demonstrates how infrared cameras allow us to see more than what the naked eye can perceive.
Laboratory Chemistry (5.310) introduces experimental chemistry for students requiring a chemistry laboratory who are not majoring in chemistry. Students must have completed general chemistry (5.111) and have completed or be concurrently enrolled in the first semester of organic chemistry (5.12). The course covers principles and applications of chemical laboratory techniques, including preparation and analysis of chemical materials, measurement of pH, gas and liquid chromatography, visible-ultraviolet spectrophotometry, infrared spectroscopy, kinetics, data analysis, and elementary synthesis.
Do you ever wonder how a greenhouse gas affects the climate, or why the ozone layer is important? Use the sim to explore how light interacts with molecules in our atmosphere.

This educational brief provides an overview of how previously unrevealed information about our galaxy and other celestial objects can be obtained by examining their energy emissions in parts of the electromagnetic spectrum other than that visible to the human eye. Remote imagery of the Milky way in several wavelengths is included, and links to additional information are embedded in the text.
Principles of thermal radiation and their application to engineering heat and photon transfer problems. Quantum and classical models of radiative properties of materials, electromagnetic wave theory for thermal radiation, radiative transfer in absorbing, emitting, and scattering media, and coherent laser radiation. Applications cover laser-material interactions, imaging, infrared instrumentation, global warming, semiconductor manufacturing, combustion, furnaces, and high temperature processing.
This NASA educator guide tells the story of why it is important to observe celestial objects from outer space and how to study the entire electromagnetic spectrum. It features a set of hands-on activities and demonstrations which can be performed by teachers to reinforce the concept that Earth's atmosphere interferes with the passage of electromagnetic radiation and to investigate the properties and uses of radiation throughout the electromagnetic spectrum.
Spectroscopy is the study of the interaction between matter and electromagnetic radiation. Molecules respond to different types of radiation in different ways, depending on the frequency - or wavelength - of the radiation. This one-semester course is designed to provide you with a more thorough description of the theory behind each spectroscopic technique as well as its applications. Upon successful completion of this course, the student will be able to: Discuss similarities and differences between spectrometry and spectroscopy; Identify the basic components of spectroscopic instrumentation; Demonstrate a working knowledge of mass spectroscopy (MS), ultraviolet-visible (UV-Vis) spectroscopy, infrared (IR) spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy; Describe how a mass spectrometer produces its spectral patterns; Explain the information obtained from a UV-Vis spectrophotometer and how it can be used for analysis; Illustrate the mechanisms that give rise to the infrared absorption bands and identify to which functional groups each correspond; Demonstrate an understanding of the processes responsible for NMR chemical shifts and splitting patterns; Elucidate the structures of organic molecules from spectral data.

Younger students can follow Echo the Bat as he travels through Arizona on an adventure to his winter hibernaculum. They will also learn how bats use echolocation to catch insects, then about remote sensing by satellites and the use of satellite imagery.
Users can read and view imagery that explains objects in our universe that produce a vast range of radiation with wavelengths either too short or too long for our eyes to see. Materials presented here show that the type of radiation emitted by an object is determined by its temperature. A table showing the types of radiation, temperatures, and types of celestial objects that emit them is included. Links to a glossary of terms are embedded in the text.
