Virtual Sojourner
Student Activity #2: Remote Rover Rock Hunt

Level 3--Map the Classroom

This activity is played between two classrooms--one is the "Site Class" and the other is the "Search Class." The Site places a "rock" (a real one or paper representation) in their classroom and moves a "rover" according to the commands from the Searchers. This version differs from Levels 1 & 2 by asking the Searchers to create a map of the Site classroom based upon information they receive from the "rover."

Suggestions for the Site Class

• Follow all suggestions given in Levels 1 & 2 except for revealing the classroom dimensions.
  
• Assume anything on the floor is a hazard capable of stopping the rover.
  
• Move the rover according to the Searcher's commands until it contacts an object in the room or the walls of the room.
  
• Report distance from the rock, distance from the starting point, and whatever object the rover is touching.
  
• Allow one "reset"--the rover is returned to the starting point unharmed.

Suggestions for the Search Class

• Follow all suggestions given in Levels 1 & 2.
  
• Use large paper for your map of the Site classroom.
  
• Try to establish the boundaries of the room before mapping its interior.
  
• Mark the location of each object you locate (touch) on your map.
  
• Be patient!
