Space Science Is for Everyone: Creating and Using Accessible Resources in Educational Settings
This brochure is offered as a tool for science, technology, engineering and mathematics educators who are working with students with disabilities. Some activity descriptions are supplemented with case study examples addressing a particular disability.
Investigating the Climate System: Clouds
This activity casts students as interns in a state climatology office. Their assignment: to investigate how clouds form, how they're classified, and their role in heating and cooling the earth. This 30-page guide also helps students understand why clouds (and the study of them) are important.
Chandra X-ray Observatory
features news and information about NASA's newest space telescope. As the world's most powerful X-rayobservatory, Chandra joins the Hubble Space Telescope and NASA's other observatories in a study of our universe, providing insights into the universe's structure and evolution. Visitors can track Chandra in orbit, watch live images from NASA-TV, and learn more about prior shuttle launch preparations.
Infinite secrets
This NOVA web site describes the recent discovery of the Archimedes palimpsest, a tenth-century copy of an ancient Greek manuscript, and examines the meaning of infinity. It offers students the opportunity to learn about mathematics history and to see how the understanding of infinity has developed through the centuries. The site contains articles, an interview, a brief video, and two online interactive activities. One activity allows the student to see how modern technology is used to read anci
Designing Assessment to Improve Physical Sciences Learning
A variety of approaches for assessing students in science classes and discusses associated advantages and disadvantages of each approach to promote student learning.
Sand pictures : what's missing?
This activity opens with pictures of traditional African sand paintings called sonas. A sona is comprised of dots and loops. One design is missing, and students are asked to study the patterns and determine the appearance of the missing design. The activity, part of the Figure This! collection of 80 math challenges emphasizing real world math, explains the importance of mathematical patterns in archaeology and cultural anthropology. The Hint suggests that students examine the number and arrangem
Combination locks : I forgot the combination! How many combinations will I have to try?
This activity asks the student to find the number of possible combinations for a lock showing the numbers 0 to 39. It is part of the Figure This! collection of 80 online mathematical challenges emphasizing real world uses of mathematics. The solution to the combination question applies the technique of using a smaller number of possible arrangements to study a problem. Students learn to use a tree diagram to model possible outcomes and explore the mathematical meaning of the term combination. Th
Middle School Portal: Math and Science Pathways (MSP2)
This is a biographical sketch of Otto Schott. Otto Schott is considered a leading pioneer in modern glass chemistry due to his creation of a variety of high quality glass for the optics industry. Copyright 2005 International Technology Education Association
Three forces on a glider
A glider is a special kind of aircraft that has no engine. Paper airplanes are the most obvious example, but gliders come a wide range of sizes. Toy gliders, made of balsa wood or Styrofoam, are an excellent way for students to study the basics of aerodynamics. This resource discussed the historical applications of the glider design, its comparison to powered air vehicles, and its ability to generate lift.

Middle School Portal: Math and Science Pathways (MSP2)
Students study the design of a remote control and re-design it to make it more ergonomically correct. Copyright 2005 International Technology Education Association
Logic for Computer Science: Foundations of Automatic Theorem Proving
This book is intended as an introduction to mathematical logic, with an emphasis on proof theory and procedures for constructing formal proofs of formulae algorithmically. This book is designed primarily for computer scientists, and more generally, for mathematically inclined readers interested in the formalization of proofs, and the foundations of automatic theorem-proving. The book is self contained, and the level corresponds to senior undergraduates and first year graduate students. However,
VRoma Project
This is a community of teachers and students who help to create online resources for teaching Latin and ancient Roman culture and who use these resources in their courses. Students and instructors can interact live and share resources for the study of the ancient world.
Online Poetry Classroom
"Songs My Teacher Taught Me," created by Teaching Fellow Anthony Consiglio, is a series of three lesson plans intended to guide students through approximately one month of poetry study. This unit involves minimal technology requirements but extends across a wide range of poetry. Of the eighteen poets included; eight are women, six are African-American; two are nineteenth-century poets and the three lesson plans are thematically broken into "What is Poetry?", "Poems of Childhood," and "Self and S
Information and telecommunications regulations and trends
The basic study material (compiled and aggregated from various sources and revised and in part written by Petrus H Potgieter) for a course Information and telecommunications regulations and trends at the University of South Africa (Unisa), available under the GnuFDL license. It discusses standards, the basics of telecommunications - including interconnect pricing - and industry issues. There is some emphasis on the South African context, but the largest part of the material is not country-specif
How to accelerate your Internet
Access to sufficient Internet bandwidth enables worldwide electronic collaboration, access to informational resources, rapid and effective communication, and grants membership to a global community. Therefore, bandwidth is probably the single most critical resource at the disposal of a modern organisation. The goal of this book is to provide practical information on how to gain the largest possible benefit from your connection to the Internet. By applying the monitoring and optimisation techniqu
Dynamic Remodeling of Individual Nucleosomes Across a Eukaryotic Genome in Response to Transcription
The eukaryotic genome is packaged as chromatin with nucleosomes comprising its basic structural unit, but the detailed structure of chromatin and its dynamic remodeling in terms of individual nucleosome positions has not been completely defined experimentally for any genome. We used ultra-high–throughput sequencing to map the remodeling of individual nucleosomes throughout the yeast genome before and after a physiological perturbation that causes genome-wide transcriptional changes. Nearly 80%
Internet Ancient History Sourcebook
The Internet Ancient History Sourcebook is a companion to the Internet Medieval Sourcebook and the Internet Modern History Sourcebook. The Medieval Sourcebook is both a classroom resource and the largest collection of online medieval texts. The Ancient and Modern Sourcebooks have a different role: since there are already ample online repositories of texts for these periods, the goal here is to provide and organize texts for use in classroom situations. Links to the larger online collections are
Cotton: Building a Better Plant
Plant genome research is already revolutionizing the field of biology. Currently, scientists are unlocking the secrets of some of the most important plants in our lives, including corn, cotton and potatoes. Secrets of Plant Genomes: Revealed! takes viewers on a lively, upbeat journey that explores how these plants got to be the way they are and investigates how we can make better use of them in the future. Plant scientists are hard at work--in the lab, in the field and at the computer--to increa

Aberrant mucin assembly in mice causes endoplasmic reticulum stress and spontaneous inflammation res
Background
MUC2 mucin produced by intestinal goblet cells is the major component of the intestinal mucus barrier. The inflammatory bowel disease ulcerative colitis is characterized by depleted goblet cells and a reduced mucus layer, but the aetiology remains obscure. In this study we used random mutagenesis to produce two murine models of inflammatory bowel disease, characterized the basis and nature of the inflammation in these mice, and compared the pathology with human ulcerative colitis.
