Each group needs:

• motion detector (see options, below)
• accelerometer (see options, below)
• belt or strap, to secure the motion detector and accelerometer to a student's body
• computer with Microsoft Excel® (or similar) application; alternatively, have students create programs using Python, Java or other programming languages that perform calculations and create graphs
• "Gaitway" to Acceleration Summative Assessment, one per person

For motion detectors, the author used Vernier products, but other motion detectors, along with the necessary accompanying graphing calculators or other similar devices, would work as well. Possible motion detectors options include:

• LabQuest 2
• Go!Motion ($109): https://www.vernier.com/products/sensors/motion-detectors/go-mot/
• Calculator-Based Ranger (CBR) 2 ($99): https://www.vernier.com/products/sensors/motion-detectors/cbr2/
• Motion Detector ($79): https://www.vernier.com/products/sensors/motion-detectors/md-btd/
• Texas Instruments CBL

Possible interface options:

• Go!Link ($61): https://www.vernier.com/products/interfaces/go-link/
• LabQuest Mini ($149): https://www.vernier.com/products/interfaces/lq-mini/
• LabQuest 2 ($329): https://www.vernier.com/products/interfaces/labq2/
• CBL 2 (for TE graphing calculators) ($166): https://www.vernier.com/products/interfaces/cbl2/

Possible software options:

• Logger Lite (free download): https://www.vernier.com/products/software/logger-lite/
• Logger Pro ($249): https://www.vernier.com/products/software/lp/

For accelerometers: The LabQuest 2 has an internal accelerometer. Possible other accelerometers include:

• Low-g accelerometer ($89): https://www.vernier.com/products/sensors/accelerometers/lga-bta/
• 3-axis accelerometer ($99): https://www.vernier.com/products/sensors/accelerometers/3d-bta/
• internal accelerometer of a smartphone (or tablet or other device), combined with a downloaded app to access data; many free or low-cost accelerometer apps are available through Google Play for Android devices; for example, the "Physics Toolbox Accelerometer" by Vieyra Software was successfully tested and data was collected and transferred to a computer
