USB plug-and-collect

The CBR™ 2 motion sensor plugs into TI-Nspire™ and TI-84 Plus families of graphing calculators using the USB CBR-to-calculator cable. Using the CBR™ 2 system and the Vernier DataQuest™ App for TI-Nspire™ technology, students can kinesthetically explore motion and graphing with the Motion Match feature.

They simply plug in the CBR 2™ device and watch the Vernier DataQuest^® App launch automatically. Once they choose Motion Match, challenge your students to match the graph by walking back and forth using the CBR 2™ device. Students enjoy changing their position and speed as they attempt to get the perfect match.

Students can also begin collecting data immediately using their TI-84 Plus family calculator (Vernier EasyData^® app required). The device will automatically launch the app and begin displaying the current distance reading. Also select from several easy-to-use activities that are already built in.
