Here are a selection of images and video links to be used for questions and comments for your Blog postings:

Pictured above is compressed, time-lapse photo of the Sun's "movements" or trails across the sky for 6 months - from June 21 (Summer Solstice) until Dec. 21 (Winter Solstice).  Which trails would represent winter - lower or higher trails and why?

Do you think the Sun rises in exactly the same place during each season?  Look at the photos above to help you with your answer.  (The Sun is rising over the same area during a 9 month period)

    #1 The sun is on the top in the summer and on the bottom in the winter.
    #2 No, because of our orbit around the sun.
    #3 The rotation of the Earth is causing this trail.

    1. During the winter the sun would be on the lower trail because in the winter the sun sits lower in the sky. The sun sits lower in the sky because the Earth is tilted away from it.
    2. No because in each picture the sun is at a different spot in the sky over the mountain.
    3. The tail is caused by the rotation of the Earth.

    1- The trails are lower if it is winter and the trails are higher if it is summer.
    2- No because our orbit interferes with it.
    3- The rotation of Earth causes the trail.

    1.) The sun is lower in the winter, and the days are shorter compared to summer when the days are longer and the sun is higher in the sky.
    2.)No, because the orbit around the sun will change it.
    3.)The rotation of earth is what causes the tail
