 InstructionsRead the introduction What causes the seasons? Did you know that the Earth's axis of rotation is tilted relative to the plane its orbit sits in by about 23.44 degrees? In this lesson we're going to start exploring how the tilt of the Earth's axis can affect how warm or cold it is. First, we need a light sensor plugged into analog pin 0. Then we're going to move around to take some measurements of how much light is hitting a particular place on the planet during different parts of the year. Since the light sensor measures how much light is striking its surface, it's a good tool to estimate how much light would be striking the surface of the planet if our model were the real thing.
3. Data Gathering
Be careful not to move the base of the globe on the table while you take your readings. Spin the globe so the city you're measuring the light for is directly facing the light. Then place the light sensor on that city, with the base of the sensor flat against the globe. Finally, while holding the sensor in place click record. Have another student help you if you can't reach everything.
