Development of scientific ideas and concepts is a continuum that extends in an unbroken sequence through all three Volumes. This is to say, Volume II lessons should not be attempted without students’ prior mastery of basic ideas presented in Volume I; the same goes Volume III versus II. Therefore, older students without significant science background should still start with Volume I. Lessons can be presented in abbreviated form in an ageappropriate way. (See abridged version of BFSU, Vol. I below.)
