Lesson Plan
Explain to students that a database is a name given to a collection of items. Point out that a telephone book is a database of phone numbers; a zoo is a database of animals; a library is a database of books; a classroom is a database of students. Brainstorm other databases with students. They might mention, for example, an encyclopedia or dictionary, a sports team, a video rental store, or a restaurant menu.
On the chalkboard, write a list of categories, such as age, eye color, hair color, and favorite ice cream flavor.
Ask students what they noticed as they participated in the activity. They should point out that the groups got smaller and smaller, that a database contains many smaller groups within the large group, and that those groups can be arranged in a number of ways depending on the criteria used.
Tell students that the World Wide Web is a database of Web sites. Within that database are billions of Web sites on millions of different topics. Ask: How can you find information you need on the World Wide Web without looking through each of those billions of Web sites? Most students will know that the answer is "by using a search engine. Explain that search engines sort the information on the WWW into smaller groups of information based on criteria the user specifies -- just as the categories on the chalkboard were used to create smaller and smaller groups of students. Ask: Why is it important to enter the most specific information possible when using a search engine?
Invite students to explore various criteria and learn about some search engines for kids by completing the Search Engine work sheet.
