Building Foundations of Scientific Understanding, or BFSU, is a three-volume science curriculum for grades K-8. Created by Dr. Bernard J. Nebel, it focuses on inquiry-based learning across various science topics, encouraging kids to explore and discover.
A peer-reviewed study published in Peabody Journal of Education found that homeschooled children are typically well-adjusted socially and score above average on measures of social skills, emotional development, and daily living skills (Richard Medlin, 2013). According to the National Center for Education Statistics (NCES), approximately 3.3 million students were homeschooled in the United States as of 2023, representing roughly 6% of the school-age population.
What is building foundations of scientific understanding?
Building Foundations of Scientific Understanding, or BFSU, is a science curriculum made for homeschoolers. Dr. Bernard J. Nebel, a Ph.D. scientist, created it. Launched in 2007, it guides kids from kindergarten through eighth grade. The program covers four main areas: Nature of Matter, Life Sciences, Physical Science, and Earth and Space Science. Instead of lectures, parents help kids learn through questions, simple experiments, and hands-on observation.
How bfsu works
Every BFSU lesson gives parents clear steps to lead kids in discovering science. It includes prompts like "Think time!" to encourage kids to ponder questions before getting answers. Lessons connect different science topics together. For instance, a lesson on evaporation relates to the water cycle and weather. This method revisits ideas with more depth as kids grow. You don't need a science background, but you should prepare by reading lessons and gathering materials.
What makes bfsu different
Unlike many elementary science programs that skim many topics, BFSU digs deep. Kids might spend weeks on one idea until they really get it. Many PhD scientists choose this curriculum for their own kids, which speaks volumes. BFSU teaches evolution, fossils, and old-earth geology, making it popular among secular homeschoolers. Plus, its focus on curiosity and careful observation attracts families who prefer more classic education styles.
Challenges to consider
BFSU isn't a plug-and-play program. Parents need to read lessons thoroughly and plan ahead. You'll likely spend 30-60 minutes preparing before teaching. There are no workbooks or worksheets for kids to fill out. Lessons require active involvement from parents, so kids can’t do them alone. Families switching from other programs might find it tricky since BFSU builds on earlier concepts. If you want less prep work, check out Scientific Connections Through Inquiry (SCI), which organizes BFSU into a more traditional format.
The bottom line
BFSU offers amazing depth at a great price. For about $100, you get three volumes covering nine years of science. The catch? It takes time to prepare lessons. If you’re ready to invest time and enjoy guiding kids through discussions, BFSU helps students truly understand science, not just memorize facts. For those wanting a simpler approach, the SCI curriculum is available with a structured format based on BFSU.
