Ever wonder how to introduce and explain databases to your 4th grade students? Well, wonder no more. This lesson is sure to teach this abstract concept in a concrete, meaningful way. After looking at several examples of print databases used in their daily lives, students will be introduced to an electronic database called Searchasaurus.

Instructional Goals: 4th grade students will understand the meaning of database. Students will learn what an electronic database is. Students will be familiarized with Searchasaurus. Learning Objectives: 4th grade students will be able to define database. Students will be able to give three examples of a database. Students will be able to name Searchasaurus as an electronic database. Motivational Goals: Students will be interested in the research process. Students will see the importance of information skills. Students will be confident in their research ability.

Examples of databases: dictionary, encyclopedia, almanac, atlas, card catalog (if applicable), OPAC (if applicable), cookbook, address book Examples of non-examples: novel, video, speech, play, classroom worksheet Chart with markers or white board Computer Projection Unit Job Aid

Introduction:
Share goals and objectives of lesson with students.

Ask, Who can tell me what a database is? Break word apart if students have difficulty. What does data mean?

Ask students to brainstorm examples of databases. As they give examples, hold up the real thing. If students need prodding, give clues and then show the actual item (phone book, dictionary, encyclopedia,
card catalog, almanac, atlas, etc.)

Ask if the following are databases and have students explain: novel, movie, address book, cookbook, speech, play, worksheet.

Explain usefulness of databases.

Define database in kid-friendly terms. Write definition on board- A database is a collection of information organized in a certain way that makes it easy for you to find what you're looking for. Have students read definition aloud in unison.

Body:
Explain that there are electronic databases as well as print.

Demonstrate how to access and use Searchasaurus, using a computer projection unit. Demonstrate by searching the general encyclopedia, animal encyclopedia, and pictures. Ask students for topics: What are you studying in S.S.? Math? Science? PE? What else, or who else, are you interested in learning more about?

Show students some pitfalls that may occur while searching. (Examples will arise when students suggest topics and LMS demonstrates searching.) For example, spelling errors (Mishigan, Iroqouis), keyword search errors (a search for bears reveals - Asparagus beds may bear for 50 years.), and No Records Found.

Emphasize usefulness of Searchasaurus for school projects and pursuit of personal interests.

Conclusion:
Recap lesson.
Review: Who can tell me what a database is? Name three examples. Can anyone think of three more examples? Why isn't a copy of a speech a database? Can you think of any others? What is an electronic database? Name one.

Explain that next time students will be paired with another student to explore Searchasaurus on their own.

Show students job aid that will help them access and use Searchasaurus next time.

Informal Assessment: Are students participating and engaged in learning? (asking and answering questions, enthusiastic) Are students exhibiting positive body language? Smiling? Can students define database orally? Can students give at least three examples? Can students name Searchasaurus as an electronic database?
