CoachLab also lets you take a simultaneous reading of water temperature that adds a more complete image of the data you are collecting. In this case an external GPS system and an external thermometer were used to log positional data to return to the same point and make multiple measurements over time. The 2 on-screen digital values can be used to observe pH and temperature data, even when you are not recording a data point. The ability to record the data, save it, export it to other programs, and manipulate it are also great advantages to using CoachLab for this kind of measurement. Additional Notes on this Activity CoachLab activities can be presented in 3 different ways that control a student's level of access and control to the program.
Flexible mode is a good choice for middle school students and above.
This activity was presented in Flexible mode in order to give you the option of altering some parameters of the test while in the field. In this experiment CoachLab I was used to record data. However, other more portable data-loggers can take advantage of the Coach software and all its features. They include TI-CBL and EcoLog. Also, the Carolina Eco-Seeker may be used to record data and upload it to a computer.
