Aim
To use a datalogger to see how conditions vary at a point on earth as the globe rotates.
Prediction*
Sketch graphs showing the variation in temperature and light levels you would expect to find as the globe slowly rotates near a heat lamp.
Temperature
0 Start (midday)
Finish (midday)
Light
0 Start (midday)
Apparatus
Finish (midday)
Globe, heat lamp, light sensor, temperature sensor, datalogger, leads, computer and monitor.
Method*
Diagram*
1. Fix the light and ________________ sensors to the globe, and connect the hardware together. 2. Start the _________________. 3. Slowly turn the ____________.
