Genesis 1:14-15 And God said, "Let there be lights in the expanse of the heavens to separate the day from the night. And let them be for signs and for seasons, and for days and years, and let them be lights in the expanse of the heavens to give light upon the earth." And it was so. (ESV)One of the purposes of God creating the Sun and Moon and stars was for signs and season, days and years, and light upon the earth. In the last few centuries we've lost a lot of the "working" understanding of the heavens as a way to mark the passing of time (days, months, years) as it has been replaced with wall calendars, electronic calendars, clocks and watches. It strikes me that the less we pay attention to the heavens, the less we often connect with God as well, because another purpose of the heavens, according to God's Word, is to display His glory. I know that for me, spending time gazing upward and reflecting, puts things on earth back into perspective and returns me to a place of worship and awe.
We started homeschool with our girls this week and one of the things I am doing is teaching them Classical Astronomy from a wonderful book called Signs & Seasons by Jay Ryan which we got at a homeschool conference. (You can find the book and sign up for free Classical Astronomy newsletters at www.classicalastronomy.com.) Classical Astronomy is the study of the heavens (which includes the Sun, our most visible star!) without telescopes, but with the naked eye as they have been done since Creation. It is like learning to read a book written across the sky by God, and it is fascinating how easily you can determine directions, times, and seasons through what He has placed there. I have found in the study that what I used to look at and not even notice (does that make sense?) I am now noticing in far different ways (the length of shadows, etc.).

Our first "field" project has been building a compass in our backyard using the Sun. The principle is that when the sun is highest (high noon, not necessarily your watch's noon) shadows point North and the Sun is South. You can tell when it is at its highest when the shadows are shortest in the day. (Incidentally, that North/South line is called the meridian, or "middle of the day" and when the sun is before it it is "ante meridian," or "am," and when it is past it then it is "post meridian," or "pm." Cool, isn't it!)
|Around 2:40 pm. We are ready to find the shortest!|
