This review is a reflection of all the Bill Nye videos in general, not necessarily any video in the series in particular. I can assure the reader, I own more than 15 of the Bill Nye science videos, so I am posting general comments and a particular criticism that may or may not be applicable the video in which this review is published.
I am a home-schooling parent who practices applied science (I design integrated circuits) and want my children to be jazzed about science. And in my opinion, Bill Nye has produced some of the best videos that keep my 6-9 yo children (both boys and girls) totally engrossed. My kids want to watch the videos 2 or 3 or 4 times in one sitting. The age-appropriateness of the videos are for grade school level thru junior high and involve experiments that are often easily repeated at home.
Having been raised in Seattle, its also fun for me to see some of the old "Almost Live" co-stars Bill uses in the video....as well as the sites from around Seattle where the video is taken.
My only criticism of the series is that the series is accompanied (peppered) with a bit of scientism sub or pseudo-scientific claims by the scientific "establishment" that are not substantiated by experiment or observation....and young minds will not able to differentiate.
For another great video series see the best of Beakman's world....great for grade-school aged children.
