my science teacher said the same thing
there is a picture of lightning on the front cover of that book ha.
since you are discounting the spark of static (cos that is just it being manifested in a particular medium and you are only witnessing the effects that it causes other stuff to have.
Really you should have said 'electromagnetism' not electricity, cos it is one thing, electricity is just electromagnetism manifesting itself differently according to the sort of stuff that is in the same locale.
like gravity....no one has seen or heard or smelt that, you have only witnessed bits of mass move towards each other and deduced that the reason is gravity.
the same for the strong nuclear force and weak nuclear force.
Of course everything is 'interpreted' via the sensors that feed into your logic processin unit.....these sensors convert the signals themselves (using electro chemical linkages and diaphrams etc) into electrical pulses in your brain so the whole premise of the original is actually facile if you take it apart (in the same spirit of the original statement)
"Not sure if it's sloppy writing or a bias against... well... commonly known science, but based on the section on electricity alone, I don't think this book should be even considered as classroom curriculum.
Heck, it might as well have said this and be just as effective:
"What is electricity? It's a difficult question because electricity is impossible to describe. One might ask the same about birds. What are birds? We just don't know"
"BJU Press is the largest book publisher in South Carolina, and more than a million pre-college students around the world use BJU textbooks." :-(
"by 1988, the BJU Press was the largest textbook supplier to home school families in the nation." :-( :-( :-(
"In August 2008, a California judge ruled that the University of California could reject high school credits for courses that had used certain BJU Press texts. The judge also ruled that the book did not "encourage critical thinking skills and failed to cover 'major topics, themes and components' of U.S. history."" :-P
