Bests & Worsts Reviews from Amazon

This is a great book, chock-a-block w/ very accessible experiments. One of the best features is the way the experiments are grouped together: a 'theme' (say, Acids, in the Chemistry section) will have a group of experiments of varying degrees of complexity that together add up to a pretty good understanding of the concept. Also, most of the materials are readily at hand- for many of them we really did already have everything in the house. This is esp. gratifying for the kids, who of course want to do the experiment *right now*. I would imagine that home-schooling families would enjoy this, but our school-going kids enjoy doing these experiments after school & on weekends. p.s., one of the easiest experiments is also a real showstopper, though it takes a couple of days to complete: dissolving the eggshell of an egg, leaving the egg inside intact!
