A near real-time map shows the division of snow and ice in the Northern Hemisphere. You can watch satellite images of the Larsen B ice shelf, which is the size of Rhode Island, collapse in western Antarctica. However, not all global climatic changes are negative. Find out why the greenhouse effect is essential to our existence.

Dear Amy: What are synergistic systems? — Pete, Jackson, Miss.

Dear Pete: Synergistic systems consist of three to four tabletops that are connected in a circle and partitioned into workspaces. Each station has two computers. Students work and learn together at the stations doing hands-on activities related to science, nutrition, history and other subjects. An example of a classroom that uses synergistic systems is at www.glenridge.org/ourtown/ gref/ syner.html. Because the students work in pairs, they learn to work with others while studying virtually any subject. This type of setting encourages students to teach themselves, allowing teachers to guide students’ learning instead of lecturing to them. (This site is no longer available.)

Dear Amy: Who gives computer and console games their ratings? — Minar, New York City

Dear Minar: The Entertainment Software Rating Board, or ESRB, rates games. Ratings are based on game content and how appropriate it is for certain ages. At www.esrb.org/ratings/ ratings_guide.jsp, you can read descriptions of each rating. You’ll also find explanations of content descriptors, such as comic mischief or edutainment, which provide additional information about games.
