  • Scanning a picture is only the first step. After a digital image is in the computer and saved as a file, students can perform various tasks involving the image. For instance, they can insert the image into a document, use graphics software to change or enhance the image, add the image to a Web page, and so forth.

  • Students can scan text in addition to pictures, but if they want the text to be editable letters and words instead of a picture of the words, they would need to use a special type of program called Optical Character Recognition (OCR) or document imaging software.

  • Before students take the lesson, show the classroom's or computer lab's scanner to students. Point out the scanning surface, cover, scan head, and lamp. Also note that the scanner is a peripheral device.

  • In this lesson, the examples use music notation. Therefore, you might want to tell students about the treble clef, bass clef, and notes, particularly quarter notes. Consider drawing the clefs and a quarter note on the board so students will recognize the symbols.

  • To illustrate how a scanner uses light to see a picture, bring a large flashlight to class. Next, post a large picture or determine an appropriate picture or bulletin board that you can use as a "picture" for this demonstration. Tell the class that they're going to pretend that they are inside a scanner, and point out the large picture or bulletin board that you are going to scan. Then have a "scanner cover" volunteer close the scanner's cover by turning out the classroom lights. Next, point the flashlight to the upper-left corner of the "picture" you're going to scan and move the flashlight left to right in progressively lower straight lines until you've scanned the entire picture. Tell the scanner cover volunteer to open the scanner cover (a.k.a. turn on the lights). If desired, you could have a volunteer or two scan other pictures or items in the classroom.
