Did You Know?

Everywhere I go, I learn interesting facts which I often refer to as "factoids"... even though I'm not actually sure that's a word. Recently, I learned this interesting tidbit from second grade teacher Mrs. Carlson:

If you look at a fiddler crab's hole, you will notice little balls of sand next to it. Line the balls of sand up in a straight line, and that will show you how deep the crab's hole is.

Try it!
