ARKive: Images of Life on Earth

Rating

ARKive is a collection of photographs, videos, and fact-files illustrating thousands of species of animals, with emphasis on the International Union for Conservation of Nature and Natural Resources (IUCN) Red List of endangered species, and on species found in Britain. For each animal there are approximately 10 minutes of video footage, 6-10 still photos, and sound recordings (where appropriate), creating a complete profile of the species' characteristic behavior and appearance. The images are accompanied by a page of facts, including taxonomy, a physical description, conservation status, geographic range, habitat, and other information. There are also links to other animals with related taxonomic families, habitats, or conservation status.

Algebra Balance Scales

Algebra Balance Scales

Rating

This online manipulative features a virtual balance scale. It offers students an experimental way to learn about solving linear equations involving negative or positive numbers. The applet presents an equation for the student to illustrate by balancing the scale using blue blocks for positive units and variables and red balloons for negative units and variables. The student then works with the arithmetic operations to solve the equation. A record of the steps taken by the student is shown on the screen and on the scale. The applet reinforces the idea that what is done to one side of an equation must be done to the other side to maintain balance. Instructions for using the applet, background information about solving equations, and teaching suggestions are included.

Alice: Learn to Program Interactive 3D Graphics

Rating

Alice is a robust and engaging programming environment that aims to give programming novices-- particularly members of demographic groups underrepresented in computer science, such as middle-school and high-school girls, community-college students, and others--a positive first experience with computer programming. With its intuitive, direct-manipulation interface, the Alice 3D program-authoring system addresses both the mechanical and sociological barriers that currently prevent many students from successfully learning to program a computer. Alice provides animated, on-screen 3D virtual objects. Alice v2.0, the current version, includes an on-line tutorial and documentation system; and work has begun, in partnership with Electronic Arts, on a powerful new version.
