The 5E Model is a research-based pedagogy that puts the responsibility for learning in the hands of students. Throughout the five stages - Engage, Explore, Explain, Elaborate, and Evaluate - student questions drive inquiry-based learning and help them to build a scientific skill set.
The 5E Model provides excitement and flexibility for teachers and students alike. Kesler Science 5E lessons give students the opportunity to take control over their own learning.

I'm Chris Kesler
My passion has always been about engaging students further and allowing them to take responsibility for their own learning. As a middle school science teacher, I developed lessons and systems that students loved. My activities were student-centered and we had a blast in my class.
These resources and activities are now available to all 5th-8th grade science teachers. I’m super happy to connect with you and look forward to serving you and your students’ needs. Together we’re going to be amazing.
