## 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, Electric Circuits Section

Our Curriculum Corner is composed of a collection of Think Sheets. Each one makes for a great component of any Lesson Plan. They work great for both independent practice exercises and cooperative group exercises. The following Think Sheet makes a great complement to this video:

Electrical Resistance

Try a Teacher Toolkit ... you might be very glad that you did. Each toolkit includes annotated links to vetted resources from across the web that we feel reliably support the specific topic. Give this one on circuit concepts a try.

Concept Builders, Electric Circuits Chapter, Resistance Ranking Tasks

This Concept Builder is focused on the variables affecting resistance. It's great practice and a great follow-up. It might even be great phun.

This Minds On Physics mission might be a bit pre-mature as the content it covers matches this video and the next video in our Tutorial series. Nonetheless it is worth mentioning and worth (eventually) doing.

Calculator Pad, Electric Circuits Problem Set, Problem #4 and #5

Improve your students' problem-solving skill with our Calculator Pad. The Calculator Pad includes problems, answers, and audio-guided solutions. Problems #4 and #5 pertain to the use of the Resistance equation from Slide 6.
Challenge your students to think scientifically, to interpret data, and to reason with one of our Science Reasoning passages. It's great for in-class work and discussion.

Lesson 3 in our Circuits Chapter of our Tutorial is all about Resistance. The following two pages are the basis of our Video Tutorial. Point your students in their direction.
