Lesson: My Angle on Cooling
What will students learn?How temperature changes as a function of distance and inclinationDiscuss how MESSENGER uses these tacticsDiscuss cause of the seasons on Earth
Activity 1: Effect of Distance on Heat
Measure how distance from a light source can affect the amount of heat that an object receives.
Activity 1: Effect of Distance
Let’s Pause for Questions.
Which has a greater effect on Earth’s seasons?
A. Earth’s variation in distance to the sun.
B. The angle of incoming sunlight on the earth.
C. The effect of the above are equal.
What is wrong with this picture?
Activity 2: Effect of Inclination
Measure how the angle at which the light source is viewed can affect the amount of heat received by an object.
Activity 2: Effect of Inclination
Outside or Inside
The Real Reason for the Seasons
Mercury’s tilt is close to 0°, how would that affect the Mercurian
seasons?
