Middle School Portal: Math and Science Pathways (MSP2)
This virtual manipulative with an interactive three-circle Venn diagram can be used to model set operations for union, intersection, and subset. For each statement, the student uses an onscreen paint function to find and highlight the region that is the solution. The student can click a button to find out if his or her solution is correct. In addition to the manipulative, there are 13 progressively more difficult logic statements to challenge the student. Instructions for use and a link to the N
Mendel's experiments
In this web lab, Gregor Mendel directs students through interactive virtual experiments. Students experiment with pea plants to discover how the seven pairs of traits that Mendel studied are inherited. The lab can be completed linearly, or students can move to a particular segment using the Sections menu. After they observe pea plants and infer the number of traits present, students perform five plant crosses. Mendel instructs students to search for patterns in the transmission of traits. Next,
Number puzzles (grades 6-8)
This virtual manipulative challenges students to solve number puzzles using one- and two-digit addition. Each puzzle requires students to arrange a given set of numbers on either a triangular or square grid so that sides or the rows, columns, and diagonals add up to a given number. Students are able to check their answers on the web site, which includes instructions for using the applet, a description of related activities, and information for parents and teachers. There is also a link to the Na
Middle School Portal: Math and Science Pathways (MSP2)
This web site contains descriptions and links to more than 60 virtual manipulatives, activities designed to function as concept tutorials. The virtual manipulatives, mostly in the form of Java applets, are designed to facilitate grades 6-8 mathematics learning. By encouraging active student exploration with computers, the virtual manipulatives can help students visualize mathematical relationships. They are organized into five categories based on the National Council of Teachers of Mathematics (
Measurement fundamentals
This lesson is from a variety of online tutorials developed for the Virtual Machine Shop. This module explores the subject of measurement. Linear and angular measurement is discussed and the inch and metric systems of measurement are compared. The uniqueness of the machine shop fraction is reviewed and examples of pronunciation are given. Animations and sound clips are provided to enhance the user experience. Users will have access to library, menu, previous, and next links to navigate throughou
A Beginners Guide to Second Life
Textbook for a Summer School Course about Virtual Worlds at UOC Barcelona.
The textbook offers a glimpse into virtual worlds in general and Second Life in particular. Titled “Mundos virtuales. Un paseo por Second Life” (“Virtual worlds. A stroll in Second Life”), the course (and book) covers a range of topics ranging from basic movement and building techniques to some theories on virtual identities.
Cross Layer Identity Management
This video addresses the problem of today's Internet users who have to pass several authentication and authorization procedures in the usage of Internet services, due to the fact that services consumed require involvement of different service providers. Such a situation exists in a Virtual Organization environment. This video presents the state of the art in federated identity management, the need for cross layer identity management, and approaches followed within the Akogrimo project. This incl
Beyond T. rex
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they learn about cladograms and the vast variety of dinosaurs that once roamed Earth. The activity opens by telling kids that there are more than 400 known species of extinct dinosaurs and by explaining how cladograms show their relationships to one another. Students then go to an interactive cladogram that has 19 dinosaur species, ranging from Velociraptor mongolienis and Eudrom
Journey to the Bottom of the Sea
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they learn about how living in the water differs from living on land. An ichthyologist first explains that ocean creatures have special features that allow them to breathe, eat, communicate, and move in water. (Each feature has its own trading card, which provides more detailed info.)Then students are challenged to "try to make the connection" by playing the Journey to the Bottom
Einstein in Time
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they are introduced to Einstein's scientific and humanitarian pursuits with two engaging, kid-friendly sections:Einstein in Time, a fascinating look at the major events in his life, presented in a time-line. Everyday Einstein: Humanitarian, a quick overview of how he used his fame to draw attention to the things he believed in.
They Glow!
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, kids learn about bioluminescence. The article contains two engaging, kid-friendly sections:"Glowing in the Ocean," a sing-along animated explanation, set to the tune of "I've Been Working on the Railroad," that looks at how marine animals use bioluminescence to "hunt a meal, attract a mate, and warn a foe."Other Glow-in-the-Dark Creatures, a quick look at how lantern fish and fla
What's the Big Idea? Biodiversity
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they are introduced to biodiversity on our planet. The online slide show covers:the three kinds of biodiversity on Earth -- genes, species, and ecosystems; just how interconnected an ecosystem is;why biodiversity is so important to our planet; the fact that extinction is forever, and how the U.S. Endangered Species Act works to protect endangered species;the ways our actions are

There are pictures of inquiry-based activities and information about other teachers who use inquiry
Field Project Tutorials: A Virtual (Structural) Field Project
This virtual five-day field mapping project allows students to construct a geological map from data provided by the web site. Students collect geologic, structural, paleontologic, strain and microstructural data observed at specific localities. Students are then able to derive a structural history for the area, including a field map, stereographs, and deformation plots. The site contains photographs and images, data, and all information that is needed to complete the exercise. It also provides s
