|Graph Matching at Lab Station 5|
- Pairs. This activity really only needs one person to walk the blue line and one person to watch the LabQuest.
- The blue line. Telling students that the motion detectors only "see" what's directly in front of them doesn't work nearly as well as giving them a visual reminder of where to stand/walk.
- The groups of four and five in my biggest class. There's not enough for that many people to do with a single set of equipment.
