This book is a big disappointment. I don't know very much about astronomy, but I have done a lot of experiments with my kids. The better experiments in this collection are basic scientific experiments we have done before with a page of explanation on how it relates to astronomy...or how it is a simulation of something in astronomy, which I feel is misleading to the kids.
Other experiments are not even experiments, but demonstrations of things so obvious that most kids can visualize them without a demonstration. For example, stirring tea leaves in a jar with a pencil to simulate a hurricane on Jupiter.
Only one experiment sounded interesting--a sun dial that can act as a compass. But wait! The compass is only accurate two days out of the year, and there is no explanation of the science behind the experiment.
I want my money back!!!!
