You have finished the animations on the seasons! Try applying
what you have learned here to your own observations of the passage of the
seasons here on Earth. As you read this, are the days getting longer or shorter?
Why? Is the weather getting warmer or colder? Why?
If you have not gone through these with the instructions or if
you did not go through this with a class at Green River College, you
can download the instructions for some exercises on the use of these animations.
For practice or guidance about what kinds of questions you can answer, check out
the instruction sheet for these animations.
