Our little lady loves science, and we have had a number of science experiment books over the years.  This one is by far our favorite.  First, the layout of the book is terrific.  Experiments are divided into four sections: Kitchen Chemistry, Physics and Making Things Move, Exploring the World, and The Human Body.  Each experiment focuses on a specific science question and includes preparation and experiment time guidelines as well as a supply listing.  Supplies are traditionally things one would already have in their home or are easily found at the grocery store.  Experiment instructions, outcome details, and explanation as to why the experiment works are included for each experiment as well as fun related facts.  The 101 Coolest Simple Science Experiments: Awesome Things to Do With Your Parents, Babysitters, and Other Adults is a great resource for indoor summer fun when it is just too hot to be outside.
