Activity Overview
Students' determine the relationship between temperature and light intensity. They use a Temperature Sensor and a Light Intensity Sensor to collect temperature and light intensity data for a period of 24 hours. They understand the effect of atmospheric factors on weather.
Before the Activity
Connect the TI-73 to the CBL™ unit
Plug in Temperature Sensor in channel 1 and Light Sensor in channel 2 of the CBL 2
