The moon was the subject of interpretation and affection for centuries. The first myth of the primitive people of the early “scientific” theories of its growth, down, Chase and constant sunshine participants developed.

Today, modern science has taught us, impresses a lot of control over the sea and sky, and its beauty still. Let your inner astronomer free – why not measure the moon?

You need a ruler, a calculator, a window, a table and a few books to explore its diameter and a true scientist:

During a clear evening, just before the full moon, choose a window through which the moon an hour can be seen from two after it rises. Then glue two pieces of tape horizontally apart on the glass about an inch and a quarter.

Place a stack of several books on the corner of a movable table, like a card table or a TV, and you’re ready to observe. Books should be about on par, if you or the observer may be lucky, her chin on the table.

The idea is to observe the moon between the two adhesive strips. Retreat (bring the table with you) until the image of the moon exactly fills the space between them, and then accurately measure the distance of the eye of the strip. The bookcase on top of the stack can help you – just to get closer to your eye. Do not let him! Safety first.

If you marked the location of your eye to the moon, measure the exact distance from the book corner, where the eye was on the tape on the glass. In addition to measure the exact width of the space between the tape.

Now you can calculate the diameter of the moon. Take your calculator and multiply you start. Make sure your measurements are correct. First multiplying the distance between the two bands by the diameter of the moon. 1.25 x 239 000 = 298 750

Then divide by the distance from the eye to the two bands on the window. We will use 137.5 cm, for example: 298 750 / 137.5 = 2.170 A miles

The diameter of the moon, produced 2.170 miles, only slightly larger than the included professional astronomers with special procedures and fancy gadgets. This project is ideal for the kids, or loved one with a human. Perhaps you see a falling star – make a wish!
