What Causes the Seasons?

Parker Moreland's modified setup for 'What Causes the Seasons' lab

Parker Moreland has been volunteering at an intermediate school in New Milford, CT, where he has come up with a clever modification of the “What Causes the Seasons” lab in our Earth Science with Computers book. First, instead of taping a temperature sensor to a globe, he opened a cardboard globe and mounted a Surface Temperature Sensor at the school’s latitude from the inside of the globe, letting it protrude just a bit. He also mounted a light sensor (homemade, in his case) inside the globe. He then monitored the temperature change when a heat lamp was placed at the appropriate angle for winter and summer sun. You can also monitor the light level and length of a day as the Earth turns with the sun in the winter and summer positions.
