Searching the Internet

    If you are looking for a specific resource, such as information on the greenhouse effect, use the search engines to find specific information, or if you have time, use the on-line Internet directories to seach by category. The automated search programs are good at finding obscure information, but can call up lots of irrelevent sites. Use the lesson plan Websites to find classroom activities for any grade or subject area.

• Using Search Engines

  There are a variety of Web search engines available for finding information anywhere on the Internet. These search engines work by gathering Web-page information and storing it in a searchable database. These Websites require that you enter the words you want to search for, locate the information in the database, and then provide a list of "hits" or Websites that have the word or words in it. [Database entries are generated by the people who create a site; They notify search sites about the new sites and provide relevent information to be placed in their database.] The Internet Resources below list some of the most popular Web-search engines.

  • Hands-on Example: To try out the search engines, go to one of the Websites and try to find information on a topic of interest to you or your students. For example, searching Lycos for "Whales" results in 6,029 Web pages with the word "Whales" on them (Your results may differ.)

• On-line Internet Directories

  In addition to the search engines above, there are many on-line organizational directories-not unlike the yellow pages or the table of contents for a printed document-that can be helpful when you're looking for something on the Internet. These Websites often provide common-sense organizational schemes for structuring the data available based on categories of things in their database. Many of these Websites include search functions as well.

  • Hands-on Example: Try finding information at the Yahoo Website on a topic of interest to you. For example, use the Yahoo directory to look under the Education section, then look in the K-12 subdirectory, Math and Science Education, and you'll find pages of useful resources for math and science activities.

• Automated Search Programs

  There are also automatic programs that can be run to seek out information on any known website, even when it's not cataloged in either a search engine or Web directory. These programs run automatically, searching every known page on websites that are publically available (i.e., not password protected). The orginal programs were know as spiders (because of the Web metaphor) and there are a variety of other names (e.g., web crawlers, robots, etc.)

  • Hands-on Example: Try finding information of interest to you in one of the automated search Websites. For example, if you search for resources on "Europe" using WebCrawler, you'll find 2,752 entries matching this term.

• Finding Someone on the Internet

  Along with the resources above, there are additional Websites you can use to find someone on the Internet. These resources only require that you know some of a person's last name to locate their e-mail address and Web page, if they have one.

  • Hands-on Example: Try finding yourself in one of the personsal directory or database Websites. For example, if your name is "Jane Floor," and you search in the WhoWhere Website, you'll find your e-mail address and your home page are listed there.

• Finding Lesson Plans

  Teachers sometimes are looking for lesson plans for specific classroom activities. There are a variety of on-line lesson plan databases available that can be searched or browsed to locate a lesson in any subject and grade level.

  • Hands-on Example: Try finding a lesson in one of the lesson plan Websites. For example, if you look for a lesson plan for Social Studies at the Teachnet.com Website you will find several, including one called "Society."
