Donate The level of science literacy in the United States is kind of a scary thing. In 2009, the California Academy of Sciences commissioned a poll to find out what kind of general science knowledge American adults have. Only 21% answered all three questions correctly. Can you do any better?

1. How long does it take for the Earth to go around the sun?
(53% of adults know this)

2. Did the earliest humans live at the same time as dinosaurs?
(59% of adults know this)

3. Roughly what percentage of the Earth's surface is covered with water?
(47% of adults know this)

To see the answers (if you need them) and to read more about the study, visit the California Academy of Sciences.
