Science Education for the Early Grades

Welcome BFSU User:

There are many points where the BFSU text advises  you to “Google _____” for photographs, graphics or other supporting information. I have created this site to releave you of such tedium. Use the forum below to click to the given lesson. There you will find direct links to the material of interest. Please inform me of links that are not working or other problems. Dr. Bernie Nebel (

All science exploration, learning, and discovery starts with, “That’s curious”, or “that doesn’t make sense.” Encourage your kids to express what is “curious” or “doesn’t make sense”, and post it in the comment boxes provided. Exploring kid’s “curiosities” is fun and helps everyone’s learning.

Please post reviews of this site with BFSU texts on Amazon.

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.)
