## Teacher Resources

The Physics Classroom has been devoted to helping students, teachers, and classrooms since the 1990s. We are as passionate about that mission now as we have ever been. If you are a teacher of Physics or Physical Science, we encourage you to use our Video Tutorial with your students. And we also encourage you to consider the use of other resources on our website that coordinate with the video. We have listed a few below to help you get started.

Curriculum Corner, Refraction and Lenses

Our Curriculum Corner section of the website includes a large collection of Think Sheets that make great complements to the video. Each Think Sheet focuses on a single concept and is structured to incrementally guide a student through the concept. They make for great follow-ups to the video, good cooperative group activities, and inclusions in any lesson plan. And if you need source documents (Microsoft Words), extended licensing rights, and solutions, consider the purchase of our low-cost Solutions Guide download. Here's a Think Sheet that fits the video quite well:

Total Internal Reflection

Our refraction simulation provides a great environment for students to explore what happens when light reaches the boundary between two materials. Combine the simulation with the use of one of our student activity sheets (we have an exceptional one on TIR) and the accompanying Concept Checker and you will have the start of a great lesson plan.

Concept Builders, Reflection and Refraction Chapter: Total Internatl Reflection

Concept Builders will help do what it's name boasts of - build a concept. This Concept Builder will test your understanding of the requirements for total internal reflection. Do it now or do it after you've watched this video and the next on the Critical Angle.

Student persistence with Minds On Physics combined with reflective thinking and the use of our Help function will put any student at the top of the class. This mission pertains to total internal reflection.

The Physics Classroom Tutorial, Refraction and the Ray Model of Light, Lesson 3, Boundary Behavior

Our written tutorial pages form the basis of most videos. So when you need a quick reference, the Tutorial page is a great place to start. This page provides coverage of the first few slides of the video.

The Physics Classroom Tutorial, Refraction and the Ray Model of Light, Lesson 3, Total Internal Reflection

Our written tutorial pages form the basis of most videos. So when you need a quick reference, the Tutorial page is a great place to start. This page provides coverage of the last 3-4 slides of the video.
