The
moon is very far away (225,622 miles to 252,088 miles depending on its position in its elliptical orbit around the Earth). NASA had to be very careful about the
calculations they made to send someone to the moon especially since the
moon is a moving target. In this activity, the kids are trying to hit
the moon (a nut suspended on a string) that is swinging back and forth. They found it very difficult to hit the moving target!
Objects appear larger, the closer they are to you:
We set up a bright lamp (our sun) and DD is moving the ping-pong ball around the earth (orange). Meanwhile LD is slowly moving the earth/orange around the sun/lamp. |
Now the kids are blocking out the orange with the smaller ping-pong ball. |
We drew pictures of the sun and showed how there was a small area where light got through with a bit of light (penumbra) and only a small portion where the sunlight couldn't pass at all (umbra). |
