Great science class warm-up!

Do your kids come to science class with cobwebs in their ears?!  :)  Get them thinking with an "Everyday Mystery" courtesy of the Library of Congress.  You and your students can ponder questions like...

Are black eyed peas really peas?
What are the Northern Lights?
What is the strongest muscle in the human body?
Who invented frozen food?

And much, MUCH more!  Start a discussion in your class today with an Everyday Mystery!
