How did scientists discover what lies beneath the earth's surface? Dig a hole? X-ray vision? Guide your class through the types of seismic waves and how these waves helped shed light on Earth's many layers. The included resources provide...

Students are introduced to the topic of electromagnetic induction. In groups, they describe ways in which the magnetic flux can change and discuss emf and current. They use different scientists laws and apply it to various scenerios in a...

Did you realize the visible light spectrum is less than three percent of the electromagnetic spectrum? A hands-onlesson includes five activities and experiments for scholars to explore and discover many advanced science concepts. They...

Students explore several parts of the body system in the eight lessons of this unit. Through several hands-on activities, the skeletal, muscular, digestive, circulatory and nervous systems are observed.

An explanation of how X-ray machines work. An online activity in which a comparison is made between how the hand would be viewed with X-ray versus with visible light. An additional page explains the use of X-rays in CAT scan devices.

[Free Registration/Login may be required to access all resource tools.] X-rays and their uses, xrays as high-energy rays and their dangers.

Learn how x-rays were discovered, and how x-ray machines and CT scanners are able to see inside the human body. Includes a video, multiple-choice and open-ended questions, background information with links for further research, and a...

The story of the word X-Ray is one of great thinkers. French philosopher Rene Descartes isolated the letters X, Y and Z to stand for unknowns, and centuries later, Wilhelm Rontgen discovered the X-ray, using the X for the unknown nature...

Investigate how we can learn about molecular structure using x-ray crystallography in this module.

Here's a really simple demonstration of a fluoroscope. There are links to more information about the uses of X-rays as well.

This page and the three pages which follow discuss how X-ray technology can be used to produce an image of the human body. Discussion is understandable and highly intriguing. Several interactive animations allow the visitor to explore...

A set of podcasts outlining a four-step process for understanding the vastness of our universe, from the vicinity of the Earth and Moon, out into distant galaxies. Downloadable instructions and a handout are included, as well as...

Students examine an image produced by a cabinet x-ray system to determine if it is a quality bone mineral density image. Students write in their journals about what they need to know to be able to make this judgment. Students learn about...

X-rays, gamma rays and beta particles are all used in medicine to treat internal organs. X-rays are produced by firing electrons at a metal target and gamma rays are emitted by the nucleus of radioactive atoms. Gamma rays are used to...

See and experience how modern science has been used to create a three-dimensional portrait of Tutankhamen, based not on Tut's famous golden but on X-rays of his mummy.

[Free Registration/Login may be required to access all resource tools.] Students learn about the important discoveries of subatomic particles, and how they led to our current understanding of the atom.

Instructional module focusing on the Silicate minerals. Discussion includes the most common minerals on Earth such as quartz, feldspar, mica, amphibole, pyroxene, and olivine. Site also includes an interactive practice quiz and links...

An explanation of how photoelectron spectroscopy can be used to detect electron structures in atoms or molecules.

Students are introduced to genetic techniques such as DNA electrophoresis and imaging technologies used for molecular and DNA structure visualization. In the field of molecular biology and genetics, biomedical engineering plays an...

See how George Eastman, Thomas Edison, and Wilhelm Roentgen impacted American film history and had inventions that were interrelated.

Have you ever wanted to see what is inside of a beetle? Each of the images provided here is from Mecynnorrhina torquata beetles unless otherwise specified. Students are able to dissect beetles with the scalpel tool to expose new parts of...

This is an extremely in depth look at the various different joints and their range of motion. Labeled diagrams are provided for each type. Illustrated quizes and x-rays can be accessed for each joint classification.

English chemist Sir William Crookes (1832 - 1919) invented the Crookes tube to study gases, which fascinated him. His work also paved the way for the revolutionary discovery of the electron and the invention of X-ray machines.

Lucianne Walkowicz shows us the waves just beyond our perception: microwaves, radio waves, x-rays and more. [5:58]
