Solutions Guide for Think Sheets

For more than 25 years, The Physics Classroom has been supporting students, teachers and classrooms in the vital tasks of learning and teaching physics. And with our Solutions Guide products, those tasks have become a little bit easier. The Solutions Guides (Physics and Chemistry) contain answer keys to each of our Physics or Chemistry Think Sheets. Answer keys contain answers to all multiple choice questions, full explanations to all short answer questions, elaborately completed details for diagramming questions, and worked-out solutions to all word problems. As an added bonus to teachers, The Solutions Guide also contains Microsoft Word formatted files of both the Think Sheets and the answer keys.

The Solutions Guides are a perfect solution for those teachers who wish to use The Physics Classroom's Physics or Chemistry curriculum with their classes. The Solutions Guides allows teachers to use The Curriculum Corner with both comfort and confidence. It is also the perfect solution for home-schoolers who use The Physics Classroom Tutorial and accompanying resources at our site as their textbook. All questions to the Physics Think Sheets are answered in great detail, transforming The Curriculum Corner into an exceptional independent learning tool. The collections of PDF files are available as two Digital Downloads (Physics and Chemistry - Both in the Digital Downloads section of our ordering system). Once the purchase is made and your identity as a teacher or parent verified, you'll receive an email with instructions to authenticate and retrieve your digital downloads. You can retrieve them at any point then in the future.

The cost of the Solutions Guides are $25.00 (US) each. You can purchase instantly via card or ACH, or if the total order is $50 or more you can create a Purchase Order. Since these are answer keys, if you are not already a verified member, there is a short manual verification check that is done (so students, don't even think about purchasing). Please use your teacher email if possible to speed up the processes.

If you have purchased in the past, please do not purchase again, but instead Contact Us and we can look up your previous order and get you a new link.

Acceptable and Unacceptable Uses

(The following licensing rights apply to those who have purchased the Solutions Guide. A separate listing of Acceptable and Unacceptable Uses for users of the Think Sheets is provided elsewhere.)

The inclusion of Microsoft Word files on this product provides teachers with the ability to easily customize and re-purpose the contents. The Physics Classroom licenses teachers the rights to do so in order to create revised handouts, quizzes, tests, PowerPoint slides and other derivatives. The license permits teachers to use the material with their own classrooms in print or digital form. This includes the uploading of files to Course Management Systems to which students have password-protected access. However, the license prohibits the placement of the product contents and files (PDFs, images, Word files) or its derivatives upon websites that are publicly accessible to others who are not from that school. If placing any of the content upon the internet, we require that access to such content be password-protected and accessible only to students from the teacher's school.

Many teachers across the country use pages from our Think Sheets assignments as graded homework (which you should use caution anyways in a world of AI...). They do not wish their students to be able to access the solutions to such homework via a Google search or other web search. When solutions are placed upon the web, the value of our Think Sheets is being destroyed for such teachers. It is not only an illegal infringement upon the copyrights of The Physics Classroom, but also an infringement upon the desire of teachers to use The Physics Classroom resources. Please do not place answers and solutions on the web where others have access to them. Thanks for complying.

Concerning Use as Homework

Our Physics Solutions guide has been out for a long time. In the past, it was an instant download, and because of that we have had situations where students have purchased the solutions guide, as well as we have had teachers place the solutions guide in areas that became public. Because of this, the 'ship has already sailed' on it being safely used as homework. Please use the Physics Solutions Guide as in class work, or ungraded homework. We plan on (in the future) redoing all the worksheets to change them up enough so any existing copies won't be usable as an answer key, and re-publishing this product behind a teacher-identity verification system.

For Chemistry Solutions Guide, however, we have now placed this behind a manual order system, where we verify the teacher's identity (usually through their email) before issuing the product. This means the Chemistry worksheets are safe to use as homework (except for AI of course).
