Students explore the many different ways that engineers provide natural lighting to interior spaces. They analyze various methods of daylighting by constructing model houses from foam core board and simulating the sun with a desk lamp. Teams design a daylighting system for their model houses based on their observations and calculations of the optimal use of available sunlight to their structure.

In this introduction to light energy, students learn about reflection and refraction as they learn that light travels in wave form. Through hands-on activities, they see how prisms, magnifying glasses and polarized lenses work. They also gain an understanding of the colors of the rainbow as the visible spectrum, each color corresponding to a different wavelength.

Through two classroom demos, students are introduced to the basic properties of lasers through various mediums. In the Making an Electric Pickle demonstration, students see how cellular tissue is able to conduct electricity, and how this is related to various soaking solutions. In the Red/Green Lasers through Different Mediums demonstration, students see the properties of lasers, especially diffraction, in various mediums. Follow-up lecture material introduces students to the mechanisms by which lasers function and relates these functions to the properties of light. In the associated activity, student teams research specific laser types and present their findings to the class.

The purpose of this course is to discuss modern techniques of generation of x-ray photons and neutrons and then follow with selected applications of newly developed photon and neutron scattering spectroscopic techniques to investigations of properties of condensed matter which are of interest to nuclear engineers.
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.
X-rays and x-ray fluorescence are not new subjects to the field of physics. Wilhelm Röntgen discovered x-rays in 1895, and in 1901 he was awarded the very first Nobel Prize in physics for this discovery. Soon after, Charles Glover Barkla discovered that each element has its own characteristic x-ray spectrum. He was awarded a Nobel Prize in physics for this discovery in 1917. Sir William Henry Bragg and his son, Sir William Lawrence Bragg, were then able to experimentally prove that the discrete electron energy levels of an atom, an idea proposed by Niels Bohr, actually existed. They were awarded the Nobel Prize in physics for this in 1915. After this groundwork in x-ray spectroscopy was established, Henry Moseley showed that each elements characteristic x-ray energy spectrum followed the predictions of the Bohr atomic model.
