AskERIC: Cell-City Project
In this AskERIC lesson plan for grades 5-9, students compare the structure and function of cell organelles to that of a working city -- a handy analogy for learning the basics of cell biology. The activities outlined in the lesson plan, which takes three to four 55-minute sessions to complete, combine art and science for an interdisciplinary learning experience. Vocabulary words, useful links, and downloadable worksheets are included along with lesson procedures.
Patterns of Gene Expression in Drosophila Embryogenesis
A new image database of gene expression patterns in Drosophila embryogenesis is now available from the Berkeley Drosophila Genome Project (BDGP), a consortium of the Drosophila Genome Center. The BDGP team used "high throughput 96-well plate RNA in situ protocol to determine patterns of gene expression during embryogenesis for Drosophila genes represented in non-redundant sets of Drosophila ESTs DGC1 and DGC2." The entire set of image, microarray, and annotation data may be browsed or searched f
History of Energy
This latest Topic in Depth delves in the Web�s offerings on the history of energy. The first site is maintained by the US Department of Energy, which is called Milestones in the History of Energy and Its Uses (1). From fire to the discovery of nuclear energy, the site gives short descriptions on significant events in the history of energy for each century, events by particular fuel type, events by energy uses, how energy uses have changed, energy consumption changes, and more. The next site
The Online Books Page
Hosted by the University of Pennsylvania Library, the Online Books Page Web site "facilitates access to books that are freely readable over the Internet...and aims to encourage the development of such online books, for the benefit and edification of all." The over 18,000 listings can be searched or browsed by author, title, and subject, of which every major physical science subject is represented. Each listing is linked to an outside Web site, making its availability unpredictable, but the shear
Mathematics Demos
For students in mathematics, it is often very difficult to visualize abstract concepts. One of the most obvious examples is the analysis of three dimensional objects, or a 3D coordinate system. This small collection of mathematics demos illustrates some of these concepts by using multi-color animations. Items such as contours, Fourier transforms, and convolution, which cannot be effectively drawn on a chalkboard, are shown in great detail here. The site also demonstrates the dimensions of the sp
An Overview of Cryptography
Gary Kessler, a computer networking professor at Champlain College, is the author of this online introduction to cryptography.
