Optical Transform (X-Ray Diffraction): Demo Kit
Simulate X-ray diffraction using a visible laser and 2-D patterns on a transparency with the Optical Transform (X-Ray Diffraction) Kit. The kit includes a manual with directions, one each of the four different diffraction transparencies, and a full-page version of each transparency. The four diffraction transparencies have these patterns:
- Unit Cell: examples for changes in unit cell size, angle, and shape; for centering with...
DNA Optical Transform (X-Ray Diffraction) Kit
Simulate Rosalind Franklin's famous X-ray diffraction experiments that led to the discovery of the DNA double helix with a laser pointer and the two-dimensional diffraction pattern transparencies from the DNA Optical Transform (X-Ray Diffraction) Kit.
The kit includes a manual with background information and directions, a diffraction pattern transparency, and projection masters. A source of visible laser light is not included, but any...
Scientific Ethics
Scientific Ethics for High School Students uses case studies to stimulate classroom discussion about various topics, such as obtaining data, laboratory safety, computing ethics, and working with others. This book contains instructions for teachers on how and when to use these case studies, along with commentaries that discuss each topic. Ethics has been used by high school teachers since 1994 to provide a useful and enjoyable means to introduce students...
Optical Transform (X-ray Diffraction) Transparencies
When students have a Optical Transform (X-Ray Diffraction) Transparency and laser pointer, simulating X-ray diffraction becomes a hands-on activity. Students see the diffraction patterns by shining a laser through the transparency and projecting the patterns onto a screen or wall. The four different diffraction transparencies have these patterns:
- Unit Cell: examples for changes in unit cell...
DNA Optical Transform (X-Ray Diffraction) Transparencies
When students have a DNA Optical Transform (X-Ray Diffraction) Transparency and laser pointer, simulating Rosalind Franklin’s famous X-ray diffraction experiment that led to the discovery of the DNA double helix becomes a hands-on activity. Students see the diffraction patterns by shining a laser through the transparency and projecting the patterns onto a screen or wall. Transparencies are available individually or in sets of 5 or 10.

Nanoworld Hands-On Student Sets
The Nanoworld Hands-On Student Sets has the materials and brief instructions for hands-on activities with LEDs and fiber optics, diffraction, memory metal, and “seeing” atoms. The sets come with mini-activity booklets that illustrate carrying out each activity and "Try This" Packets. Each "Try This" Packet includes the materials needed to demonstrate the activities and contains:
