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 learning exercise, students read an article about social X-ray glasses and sociometric  badges, then complete a set of 29 comprehension questions.

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...

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. 

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...

How and why barium is used in X-rays is the focus of a video that also describes the similarities with bones, the insolubility, and the medical applications of this element.

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.
