Cell Biology and Cancer
The National Cancer Institute, part of the National Institutes of Health, has recently released this curriculum supplement as part of a series designed to "deepen students' awareness of the importance of basic research to advances in medicine and health," as well as foster critical thinking and an understanding of how scientific discoveries affect their own lives. The Web site offers five outstanding student activities (grades 9-12) regarding cancer and cell biology. Some of these activities hav
National Center of Competence in Research (NCCR) on Climate
The National Center of Competence in Research (NCCR), based in Bern, Switzerland, studies climate change and its impacts on society through "reconstruction of past climate; study of key physical, chemical and ecological processes; and a concerted effort to develop procedures for seasonal forecasting as well as the forecasting of extreme weather events." This extensive website offers summaries of the goals, methods, status, and results for the NCCR's fourteen main projects. While some of the publ
Center for Earth and Planetary Studies Research and Publications
The Center for Earth and Planetary Studies (CEPS), which is part of the Smithsonian's National Air and Space Museum, "conducts an active research program in planetary and terrestrial geology and geophysics using remote sensing data from Earth-orbiting satellites and manned and unmanned space missions." The Research portion of the site allows visitors to view the many projects that have taken place, such as the Topographic Mapping of Mercury project being conducted by Dr. Anthony Cook. Each page
ESA: Launchers
The European Space Agency (ESA) furnishes thorough articles and images regarding its launch vehicles, Europe's Spaceport, and technology. Users can find out ESA's launch schedule, plans for next generation launchers, and the past successes of the launch program. The website offers a video of a launch countdown, images of the Ariane 5, and many more media materials. Through the interactive modules, individuals can learn about the stages, boosters, engines, and additional specifics of the launcher
Gender and Science Digital Library
A new project from the Gender & Diversities Institute and the Eisenhower National Clearinghouse, the Gender and Science Digital Library (GSDL) is a major initiative to create an interactive digital library of high quality gender and science resources. The library will assist K-12 educators in providing equitable science education by raising awareness of the effects that gender has on learning science and sharing teaching methods to address gender differences. The site is currently seeking educat
Jen's home of multicultural math games
This website includes descriptions of three mathematical games from different cultures: Mancala, a counting game from ancient Egypt; Rithmomachia, a 'battle of numbers' board game dating back to 1150 and used by Roger Bacon to teach arithmetic; and To-pe-di, a Native American game of chance. Each game is illustrated. Other terms: geometry, Boethius, Pythagorean number theories, dice sticks. (Includes 5 references)
1 Using the learning journal Keeping a reflective journal (or learning journal) can help you while studying the material in this – or in fact any OpenLearn – unit. A journal is a tool for self discovery, an aid to concentration, a mirror for the soul, a place to generate and capture ideas, a safety valve for the emotions, a training ground for the writer, and a good friend and confidant. Introduction to Scanning Probe Microscopy GC Splitless Injection Animation Basic Electronic Tutorials On AC, DC, Semiconductor, and Digital Theory Introduction to Signals and Noise: eLearning Module Exploring The Forces of Tension Floating and Falling Flows Introduction to Statistics Strum Along Renew-a-bead Time Flies When You're Having Fun!

This learning module teaches the principles behind scanning tunneling microscopy and atomic force microscopy. The module includes example applications and ample literature citations.
This site is one in a series of sites with very good animations related to separations. This animation deals specifically with splitless injection in GC. The animations are short (one to two minutes) and can easily be shown in class as part of a lecture. They are extremely helpful in illustrating key components and concepts of chromatographic systems. Users are encouraged to explore the site and the other brief animations as well. Separate links to other simulations by the same company (TRSL) ar
This website serves as an excellent tutorial on basic AC and DC electronics, semiconductor operation and digital theory. Experiments are included to illustrate these concepts. The material is sufficiently comprehensive and is highly recommended as a starting point for students interested in learning about basic electronics.
Basic concepts of signals, noise, and extraction of data from noisy signals are presented as an e-learning module. Excel spreadsheets allow students to vary noise parameters. Basic electronics ideas relating to RC circuits support introductory information on filters
Students will review their knowledge of tension and focus on tensile loads and failure caused by them.
Students discover fluid dynamics related to buoyancy through experimentation and optional photography. Using one set of fluids, they make light fluids rise through denser fluids. Using another set, they make dense fluids sink through a lighter fluid. In both cases, they see and record beautiful fluid motion. Activities are also suitable as class demonstrations. The natural beauty of fluid flow opens the door to seeing the beauty of physics in general.
Introduction to Statistics. Random Variable, Mean, Variance, Standard Deviation and Mathematical Expectation. Discrete Distributions: Bernoulli trials and Bernoulli distribution, geometric distribution, Poisson distribution. Continuous Distributions: random variables of the continuous type, uniform distribution, exponential distribution, gamma distribution, chi-square distribution, normal distribution, t-distributions. Estimation: biased and unbiased esimators, convidence intervals for means, co
Music and sound are two different concepts that share much in common. Determining the difference between the two can sometimes be difficult due to the subjective nature of deciding what is or is not music. The goal of this activity is to take something constructed by students, that would be normally classified as just sound and have the class work together to make what can be perceived to be music. Students will construct a basic stringed instrument made of a shoebox and rubber bands. This activ
A quantitative illustration of how non-renewable resources are depleted while renewable resources continue to provide energy. The activity requires students to remove beads (units of energy) from a bag (representing a country). A certain number of beads are removed from the bag each "year." At some point, no non-renewable beads remain. Groups of students have different ratios of renewable and non-renewable energy beads. A comparison of the remaining beads and time when they ran out of energy sho
These activities will give you practice in telling time. First, try Matching Time at this website. Telling the Time is easy if you practice! Please tell me, What Time Is It?
Eggs are the means through which chickens reproduce. Hens lay the eggs and incubate them so they will grow. The egg has all of the nutrients the chicken embryo needs to develop into a baby chick and helps protect it as it matures.
Squirrels use their teeth to bite into and crack open chestnuts and other kinds of nuts. Their teeth leave marks on the nutshell after the squirrel has cracked it open to get the nut that is inside.
HPV (human papillomavirus) is transmitted by skin-to-skin contact. Some types of HPV can cause cancer, while others cause genital warts.
