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.

Adaptations That Help Gray Whales Survive
Rating

Animals are faced with a constantly changing environment which they must adapt to. This lesson looks at gray whales and the specific adaptations these animals have made in order to develop crucial abilities such as keeping warm in icy water, seeing underwater and knowing when it's time to migrate. Students can click on four different areas: the whale's body, head, flippers and tail, and learn how each body part helps gray whales to thrive in their environment.

Algebra Balance Scales
Conditions of Use:
Read the Fine Print
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.
