Algebra Balance Scales
Read the Fine Print
Rating
0.0 stars

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.

Antarctic Ice Movement Part I
Read the Fine Print
Rating
0.0 stars

With more than 29 million cubic kilometers (7 million cubic miles) of ice and snow, the Antarctic Ice Sheet is so massive that its weight depresses the underlying crust by 900 meters (nearly 3,000 feet). New snow that collects on the ice sheet's surface causes the ice beneath it to spread out and move along the slope of the land. In this video segment adapted from NOVA, a team of glaciologists carves into one glacier on the East Sheet to monitor the nature and speed of its movement.
