Using The World Wide Web

Web Browsers A computer program that lets you access the WWW and “browse” the Internet for information Common browsers : Netscape Navigator Internet Explorer Mosaic

Web Sites A single group of many pages dealing with the same topic and written by the same person is called a Web site. A Web site is like a magazine with many articles. A home page is like a front cover that tells what is inside.

Hypertext Links Underlined words on a Web page that allow you to jump to another place or Web page They look like this : the survey included Hidden codes are attached to these words This coding is called Hypertext Markup Language (HTML)

More on Links The links might be in the form of pictures such as Links might lead to text, video, or sounds When you move your cursor over a link, it turns into a pointing finger

The Browser Toolbar : Netscape To go to the home page To move backward one page To find a word on that page To stop a page from loading To print that page To go forward one page To open a dialog box to type a URL

The Browser Toolbar : Internet Explorer Read Newsgroups Open Send Refresh Open Favorites To move backward one page Change Font Size Edit Source Stop Search the Net Add to Favorites To move forward one page Start Page

Uniform Resource Locators A URL is the unique address assigned to each page on the Internet Your browser uses the URL to find information located on another computer and to retrieve the corresponding page situated on that server

Anatomy of a URL http://www.capecod.net/schrockguide/eval.htm Hypertext Transfer Protocol Directory on the server Address of ISP File name (HTML format) Networkdomain

Different Protocols on the Net http:// hypertext transfer protocol (WWW) ftp:// file transfer protocol gopher:// gopher site news: newsgroup telnet:// telnet mailto: e-mail address

Different Domains on the Net .com commercial .net network .edu educational .org organization .mil military .gov government

Spirographs and Math! http://juniper.tc.cornell.edu:8000/spiro/spiro.html Site with a program to generate Spirograph designs on the computer Help students enter integers at the site for the radii of the fixed and rotating circles Challenge your students to re-create the design with a real Spirograph

1492 Columbus http://www.millersv.edu/~columbus/ Students can travel with Columbus on a virtual field trip Have students create a Hyperstudio presentation using information from this site Have students change the situations and therefore the outcomes

Food Guide Pyramid http://www.servtech.com/public/cecarlin/maypotm/food.htm Site provides information about the food pyramid and an illustration Have students create a survey for their classmates to find out how healthy their eating habits are and enter the results in a database or spreadsheet

How To Find What You Want

Directories vs. Search Engines Lists of Web sites added by a human May be general or subject-specific Yahoo : general Kathy Schrock's Guide for Educators : subject-specific Search engines An index built by a computer program that goes out and collects data More inclusive than a directory Keyword searchable

Successful Searching Combining terms is called Boolean logic Combine terms to both expand and limit your search Most search engines have an advanced feature that allows this

Only returns pages with both of these terms on them Boolean Logic : AND Limits your search Women & History Only returns pages with both of these terms on them

Returns every page with either of these terms on them Boolean Logic : OR Broadens your search Women or History Returns every page with either of these terms on them

Only returns pages that contain one but not the other term on them Boolean Logic : NOT Limits your search Women not History Only returns pages that contain one but not the other term on them
