X-rays

A simple, single page assignment asks wave masters to record the wavelength of the x-rays coming from a powder diffractometer and perform calculations with it. Equations, energy level diagrams, and a periodic table are all included....

In this X-ray specs instructional activity, students read an article about social X-ray glasses and sociometric  badges, then complete a set of 29 comprehension questions.

High school engineers experiment with passing light through mesh and perform calculations using the diffratction equation. This all-encompassing lesson includes the activity sheets for four different diffraction activities and a page of...

A striking PowerPoint that presents the Yohkoh Telescope, some information about its construction, and the amazing x-ray images of the sun that have been captured. Specific information about the electromagnetic phenomena is given. This...

How do x-rays work? Where they are on the electromagnetic spectrum? Why they are good for showing bones and tumors? How does a CT scan work? All these questions are answered by a short video that also briefly discusses ionizing...

By examining coral skeletons with powerful X-ray technology, scientists are able to track climate change before written records were produced. Learn how in a fascinating video short video.

A gamma-ray burst might have caused the mass extinction 450 million years ago. The video introduces the concept of gamma rays and gamma-ray bursts. Then it explains what happens if they were to hit Earth and why we can't prepare for any...

This link takes you to a comprehensive unit that delves into emission spectra and supernovas. There are four parts: How and where elements are created, electromagnetic radiation, spectroscopy, and the newest technology for studying our...

Your young scientists will see that accidents and making mistakes are a common theme in science as they are tantalized by this short video clip that details the mechanics and history of the CT scanner and x-ray machine. 

Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.
