ABSTRACT
To help physical science teachers make sense of how to effectively sequence lessons, this chapter summarizes using an exploration-explanation sequence of instruction to teach Bernoulli's principle to prospective middle and secondary science teachers in a science Methods course. It utilises demonstrations during Bernoulli's unit to help students go back and forth between their observations of phenomenon and what occurs at the microscopic level, using what we have termed "molecular talk." Due to the success of this unit, we would like to provide students with even more real-world elaborations and in the future have them investigate how Bernoulli's principle applies to other real-life circumstances such as the aerodynamic lift that occurs with an air plane wing during flight. While sequencing science lessons in an exploration-explanation sequence presents some challenges, it helps students to make connections between their experiences and to make sense of abstract scientific terms and concepts.
