C. Running the EA100 Using the program “Light”

Linking the EA100 to Graphing Calculator

Make sure both calculator and EA100 are turned off. Link the two using the data

transmission cable. Remember to make sure it snaps. Turn both machines back on. This

activity requires the light probe, a light source, such as flashlight, and a way to measure

the distance away from the light source to the probe.

Running the Light Program/Actually conducting the Experiment

From the Program area of the Graphing Calculator, select and run the program called

“Light”. The program asks for the number of points or samples to be taken, and then each

time you must also type in the appropriate distance away. The data is automatically

placed in List 1 for Distance, and List 2 for relative brightness. The statistics graph is

defined as a scatter plot with x values being distances (List 1) and y values being relative

brightness (List 2).

Comparison to Using the Multimeter Setup

This was done earlier by hand. First we recorded the data into a chart, transferred it into

the lists area, setup a scatter plot and then tried various regressions. This is now done

instantaneously simply running the program. The focus of a program takes the emphasis

off of the setup of the experiment and running of the equipment and allows you to spend

more time analyzing the data. This has many positives as well as negatives. Much learning

is done by having to choose your own sample time and rate, as when using a program this

is done for you.

Extension/Other Suggestions: Notice in the Appendix that their are programs for each

of the autosensing probes. This will allow each one to be driven by the graphing

calculator. You might have the students type in these programs or transmit them from a

source calculator in order to experience the ease of use of using each of the probes with a

program. Another Suggestion is to modify one of the programs to change the rate of

sampling, or even the number of samples.
