X-rays

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

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

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...

Hop into a resource on Beer's Law. A PowerPoint presentation introduces Beer's law as part of calculating bone density from X-ray images in the sixth lesson in the series of seven. Individuals work on practice problems with this law and...

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...

More of a math lesson than physics or space science, high schoolers take a set of data and plot it on a log-log coordinate system. The write-up for day two was never completed, but day one, "Stars and Slopes," is complex and cohesive....

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.

Bone up on bone density. The second installment of the seven-part series has pupils read articles on two different websites to learn about bone density and its measurement, as well as X-rays and other imaging tools. A quiz assesses their...
