Eric Johnston 9/10/07 MAED/SCED 276 POW #1 CBL for Life? A CBL, Calculator Based Laboratory, used to obtain data from sensors as a function of time. This data is then transferred to a graphing calculator for analysis. With a CBL you can measure data using different probe attachments. The various types of data able to be collected are temperature, voltage, current, magnetic field, light, sound, acceleration, force and motion. A mock data set for this device would be a person walking. The CBL would record the distance away at each time interval. Time(sec) 1 2 3 4 5 6 7 8 9 Distance(f t) 2 4 6 8 11 17 24 27 27 The CBL would automatically calculate velocity and acceleration. In a math class I plan on incorporating this into my classroom because it would show an actual physical example of an object moving, taking measurements, and determining important data such as velocity, acceleration, distance, and time. The students could record data on their own and calculate each quantity while checking it with the CBL. http://www.ncsu.edu/sciencejunction/route/technology/CBL/1/4appendixA.html
