5.0 out of 5 stars
Excellent experiment book for ages 4-12!, May 16, 2008
This review is from: 501 Science Experiments (Hardcover)
Covered in 501 Science Experiments is Astronomy, Biology, Chemistry, Geology/Geography, Physics and Weather all separated with handy tabs. This book is friendly to both a homeschool and classroom environment and I've been looking for an organized experiment book like this for a while. Easy to do experiments most of them are with everyday materials.
This is a hardcover binder type book with the inside pages wire bound, each section has a page to track the experiments done which is very handy.

bad science, December 19, 2009
This review is from: 501 Science Experiments (Hardcover)
These are not "experiments" and the science is often bad and often not explained at all. These are great kid's activities and they can be used to illustrate many science concepts. But the teacher needs to make sure that the correct scientific concept illustrated by the activity. For example, #6 is called "Making Gravity" but gravity is not made at all with this activity, rather centrifugal force. So, to you this book you need to make sure you understand the science involved and provide your own explanation.

Excellent Book. One warning - don't mix vinegar and bleach!, July 4, 2011
This review is from: 501 Science Experiments (Hardcover)
This is an excellent book of experiments for kids. Most of the experiments have a lot of great potential for fun and learning, yet require very simple and safe tools that most people will have on hand.
I do want to issue a STRONG WARNING that at least one activity in the book calls for combining vinegar and bleach, which is potentially toxic (produces deadly chlorine gas). The book does not warn kids about the potential hazards of this combination, and thus this is a major flaw. It would also be nice if the book gave a more detailed explanation of the science behind the more complicated experiments. However, these are the only two drawbacks, and this is probably the best science book I've found for my son (who is nine). Aside from the aforementioned problems, almost all of the experiments are safer, easier, and friendlier - not to mention more educational - than most activities that I've seen in other books.
