Do Americans know their science? The results are in from a new National Science Foundation survey that assessed our knowledge of basic biology, chemistry, astronomy, geology, and physics -- and they don't look promising.
The survey shows that an alarming number of Americans think astrology has a foundation in science (it doesn't). And too many of us don't know what determines a baby's sex or the correct answer to the simple true-or-false question "The universe began with a huge explosion."

1. The center of the Earth is very hot. True or false?
2. The continents have been moving their location for millions of years and will continue to move. True or false?

4. All radioactivity is manmade. True or false?
5. Electrons are smaller than atoms. True or false?
