The final piece/performance is a culmination of the experience and knowledge gained over the semester. There are two related activities in the Refraction section of the Science Reasoning Center that will challenge students to employ close reading, data analysis, and logical reasoning. Science classrooms should be filled with reasoning activities. The Laboratory section of The Physics Classroom website includes several hands-on ideas that complement this Interactive. Simulations should always support (never supplant) hands-on learning.

Curriculum/Practice: Several Concept Development worksheets at the Curriculum Corner will be very useful in assisting students in cultivating their understanding, most notably.

Visit the Minds On Physics Internet Modules. They are best used in the middle to later stages of the learning cycle. Assignments RL1, RL2, R元, and RL5 of the Refraction and Lenses module provide great complements to this Interactive. The Minds On Physics Internet Modules include a collection of interactive questioning modules that help learners assess their understanding of physics concepts and solidify those understandings by answering questions that require higher-order thinking. The following pages will be particularly useful in the early stages of the learning cycle on refraction: Lessons 1 and 2 of the Refraction and Ray Model of Light Chapter of the Tutorial are perfect accompaniments to this Interactive. There are numerous resources at The Physics Classroom website that serve as very complementary supports for the Refraction Interactive.

Total Internal Reflection Concept Checker (based on Activity #3).

Refraction Concept Checker (based on Activity #1).

Then follow it up with the Concept Checkers: The other focuses on total internal reflection and the critical angle it complements Activity #3 (above). Our Refraction simulation is now available with two Concept Checkers - one focuses on refraction and the direction of bending it complements Activity #1 (above). This second activity sheet also makes for a great makeup-lab for those students that missed the hands-on version of it. If they are not, this Interactive may be the next best way of approaching Snell's Law using data-collection and analysis. The Physics Classroom recommends that the hands-on version of this lab be performed if the materials are readily available. The third activity sheet represents the use of the Interactive in more quantitative way. The activity also has the learner explore the conditions under which incident light will undergo total internal reflection.

Learners recognize that increasing the angle of incidence causes an increase in the brightness of the reflected ray and a decrease in the brightness of the refracted ray. Learners investigate the effect of the angle of incidence upon both the angle of refraction and the relative brightness of the reflected and refracted rays. The second activity sheet focuses the learner's efforts on understanding the dual behavior of reflection and refraction at the boundary between two materials. It is advisable to select the questions that fit best with the course curriculum and philosophy. It is not recommended that you assign every question to each student. And finally, learners can answer the question using the format of a claim (answer), evidence (references to collected data) and reasoning (use of logic to explain how the evidence supports the claim). Variables must be controlled others must be altered observations and measurements must be made. Several questions are presented and learners must determine a procedure for answering them.

The first activity sheet provided by The Physics Classroom provides learners with an inquiry-based activity.
