The gold standard for instruction in elementary science education has been the BSCS 5E Instructional Model.  Developed by Busby while at BSCS in Colorado Springs, maybe, it has a catchy catchy name and is clever blend of constructionist and instruction.  At the very least, it reminds teachers to teach, not just to instruct.

The folks who developed Science4Us were enthralled and inspired by the 5E Instructional Model and implemented the 5E Instructional Model for the primary grades with fidelity and creativity.

Looking forward, there is renewed emphasis on authentic investigative science and it remains to be seen for 3rd- 5th grade this can be merged with the 5E Model. Stay tuned. What’s also fun is how this has been made available to elementary homeschool science learners.
