CP,

There is a series of easy reader science books (with substance) by DK entitled EYE WONDER. There are tons of photographs and diagrams with captions along with the text so that a child with some subject experience (and a high IQ) might be able to decipher the words.

Non-Fiction science books on the following topics were my son�s favorite when he was 5-7 years;

Volcanoes
Black holes
Electromagnetic Spectrum
Reptiles
Rocks and minerals
Periodic Table
Atoms

I like Trinity�s suggestion for clubs also. We haven�t found any around here, but ds loves to attend rocks and minerals shows.

Are you considering a grade skip?
