I only just became aware of Afarensis' effort called Transitions ,a blog aimed at high school to early college students who are fairly serious about evolutionary biology, with an emphasis on the fossil record. The posts I looked through are very well written. Take a look!
UPDATE: The BBC has a whole series called In our time dedicated to human evolution.
And, via Slashdot, science fair entries from hell . Pot muffins in Santa Cruz-- who woulda thought?
