The Indian Ocean Basin is becoming an important topic in middle and high school world history and geography courses, but one for which there are few instructional resources. This web-based resource helps teachers incorporate the Indian Ocean into world history studies by illustrating a variety of interactions that took place in the Indian Ocean during each era. The material is assembled into an integrated and user-friendly teaching tool for students in upper elementary, middle and high school. It offers students the chance to investigate primary sources that illustrate historical interactions, helping them to become more adept at the analytical historical thinking skills that are required by virtually all state history standards today.
If two inscribed angles intercept the same arc, then the angles are equal. Drag the orange points to change the figure.

A dynamically simplified solar system is constructed from online data to explore the real solar system on many different scales.
The realistically scaled solar system is surprising because nothing is visible due to the presence of many different scales. That is why it is usually rescaled in animations or illustrations. This is nice but gives us a wrong sense of distances and sizes. This Demonstration is intended to show the solar system's different scales in their full glory.
Since it is hardly possible to see anything when the real scales are used, controls have been added to modify the sizes of the celestial bodies.
Mumkin offers practice materials for learners who are at a beginning, intermediate, and advanced level. Materials are grouped by difficulty level, and consists of videos in Arabic daily life followed by comprehension questions in the form of multiple choice or fill in the blank questions. Users also have the ability to read an Arabic transcription of each video. The site also provides a series of songs in Arabic that depict some aspect of contemporary Arab life along with the lyrics to the songs.
An annotated linguistic resource which shows the Arabic grammar, syntax and morphology for each word in the Holy Quran. The corpus provides three levels of analysis: morphological annotation, a syntactic treebank and a semantic ontology.
The Read Arabic! Internet lessons were developed at the National Foreign Language Center (NFLC) at the University of Maryland primarily with high school students of Arabic in mind; however, the materials can also be used for those in college at the basic and intermediate level as well. The website assumes knowledge of the Arabic alphabet and how to read. In addition to lessons, the website includes a basic overview of the Arabic language in English, from its history to modern usage, and learning suggestions.
Algebra students need practice determining equations of lines given a pair of points, or the line parallel or perpendicular to a given line through a given point. This Demonstration, along with guiding worksheets or a teacher presentation, gives students a chance to see the relationships between these lines and points.
The mission of Understanding Science is to provide a fun, accessible, and free resource that accurately communicates what science is and how it really works. The process of science is exciting, but standard explanations often miss its dynamic nature. Science affects us all everyday, but people often feel cut off from science. Science is an intensely human endeavor, but many portrayals gloss over the passion, curiosity, and even rivalries and pitfalls that characterize all human ventures. Understanding Science gives users an inside look at the general principles, methods, and motivations that underlie all of science. This project has at its heart a re-engagement with science that begins with teacher preparation and ends with broader public understanding. Its immediate goals are to (1) improve teacher understanding of the nature of the scientific enterprise, (2) provide resources and strategies that encourage and enable K-16 teachers to reinforce the nature of science throughout their science teaching, and (3) provide a clear and informative reference for students and the general public that accurately portrays the scientific endeavor. The Understanding Science site was produced by the UC Museum of Paleontology of the University of California at Berkeley, in collaboration with a diverse group of scientists and teachers, and was funded by the National Science Foundation1. Understanding Science was informed and initially inspired by our work on the Understanding Evolution project, which highlighted the fact that many misconceptions regarding evolution spring from misunderstandings of the nature of science. Furthermore, research indicates that students and teachers at all grade levels have inadequate understandings of the nature and process of science, which may be traced to classrooms in which science is taught as a simple, linear, and non-generative process. This false and impoverished depiction disengages students, discourages public support, and may help explain current indications that the U.S. is losing its global edge in science. Even beyond the health of the U.S. economy, the public has a genuine need to critically assess conflicting representations of scientific evidence in the media. To do this, they need to understand the strengths, limitations, and basic methods of the enterprise that has produced those claims. Understanding Science takes an important step towards meeting these needs.
