Biology for Kids by Liz Lee Heinecke
Here’s a book that’s excellent for kids interested in doing experiments. Each of the 25 labs starts with a short biography about a scientist in the field of biology, followed by an experiment related to their field. Study fingerprints, grow mold, draw flowers, learn how mosquitoes transmit disease, and so much more. This would be an excellent book for homeschoolers, and would go well with Chemistry for Kids which is the same type of format.
