The Web uses hypertext, which means that certain words (or graphics) are highlighted and underlined (often in in blue), and if you click on them using your mouse (left button), you will be connected to additional information on the subject. You may also click on graphic images, or on icons.
If you observe your mouse pointer arrow, when it turns from an arrow into a pointing finger, you are on a clickable hyperlink. Also note that if a hyperlink is in red (or another color), it just means that it is a site you (or someone on your computer) has visited before.
These features are useful for education because they provide tutorials, classroom activities, and up-to-the minute data and photographs (such as pictures from the Hubble Space Telescope, satellite weather maps, maps of the ozone hole, current earthquake information, etc.)
As you view the hypertext files, I recommend that you read (or at least skim) the entire file before clicking on the highlighted words.
If you wish to access a particular address, you can type in the address you need. (Using your mouse, click on the first part of the address, and holding the button, drag it along until the current address is highlighted. Then, just start typing the new address.)
Or, you may want to "bookmark" the assignment page, to return to it.
Print out the assignment page, and write your answers on it to turn in.
