I expect that you will have the following items in your main lesson book so far:
1. Biography of Erastothenes and Aristarchus
2. Seasons (including information about the Tropics of Cancer and Capricorn, information about the solstices and equinoxes, and information about the maximum altitude of the sun during any time of the year)
3. Circumference of the earth
4. Moon Phases (including information about eclipses)
5. Sunset (leave a facing page blank for a later drawing)
6. Drawing of the big dipper, Polaris and Arcturus.
7. Scale drawing of the Solar system. This should include both a scale drawing of the distance of each planet from the sun as well as a scale drawing of the size of the planets I would also like you to include a map of the current position of the planets relative to each other and the sun. You can find a model of this here.
8. Parallax (see post above)
9. Astronomy Timeline
10. Sundial
Mr.Hatfield, I wanted to make sure that the Circumference of the Earth assignment was from when we found how to calculate the Earth's circumference. Also, in that assignment you had said that the numbers we were using were not accurate. I was wondering if this applied to all of the latitudes and altitudes that we worked with that day, or if some were real. For example, is the maximum altitude of the Sun 63 degrees or was that just an example?
ReplyDeleteThank you so much,

Yes Circumference of the Earth = Earth's circumference. The figures that I used to calculate the circumference of the earth were made up. However, when I calculated the maximum altitude of the sun I was using the latitude for Portland, which makes those numbers accurate. Sorry for the confusion.
