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. The following Think Sheet allows students to practice the use of the lens equation and magnification ratio.

The Calculator Pad, Refraction and Lenses Chapter, Problem Sets RL14 - RL20
The Calculator Pad is a powerful tool to assist students in learning to solve Physics problems. Our collection of problems is organized into problem sets according to topic and difficulty level. The above sets target the use of the lens equation and magnification ratio. Students solve a problem and receive immediate feedback. Many problems are accompanied by an audio-help file that provides some details regardingi the solution; other problems consists of links to appropriate tutorial pages. Students can have multiple attempts on each problem, allowing them to correct their mistakes. Teachers with Task Tracker accounts can modify the problems sets, write their own problems, and track the progress of their students.
The Physics Classroom Tutorial, Refraction and the Ray Model of Light, Lesson 5, The Mathematics of Lenses
Our written tutorial pages form the basis of most videos. So when students need a quick reference, the Tutorial page is a great place to start. This page is a great written version of the video.
