Globe Probe

Use the Light Sensor to investigate Earth’s climate and seasons.

Ever wondered why it’s so frigid at the poles? Shine a lamp sideways on a globe in a dim room and you’ve got an excellent model of our Sun-illuminated Earth. Use the Light Sensor in Science Journal to measure how illumination level changes as latitude changes. You can also try tilting the Earth in other directions to measure the effect of seasonal shifts.
