Explain to students that a computer is both an input and an output device. Some parts of the computer, such as the mouse and the keyboard, are used to put information into the computer. Other parts, such as the monitor and the speakers are used to get information from the computer. Point out that computer users need to put in information correctly in order to get out the information they need. Tell students they are going to learn how to use the mouse to input information by exploring the Mouserobics tutorial. Then provide them with the Mouserobics Scavenger Hunt to complete when they are done with the tutorial.
Note: The part of this lesson described above might be completed with students gathered around a single classroom computer, with a projected image of the Web site as the whole class explores it together, with students working at individual computers in a lab setting, or with students working individually at a learning center computer.
