Think Sheets

Welcome to the Think Sheets (Formerly Curriculum Corner)

Our Think Sheets consists of a collection of downloadable PDF files designed to complement the resources at The Physics Classroom. The files serve as classroom-ready handouts to be used by teachers with their classes. We have over 100 sheets for both Physics and Chemistry, covering our wide variety of topics. In 2025-2026 we added AP Physics 1 Topics and are hoping to fill in those missing topics in the 26-27 school year.

Uses for our Think Sheets

The Think Sheets for our Physics and Chemistry Topics are designed to support students as they progress through topics in our Tutorials (online textbook). Each Think Sheet in a given unit is linked to a page (or multiple) at one of the Tutorials. The URL of the corresponding Tutorial page is listed at the top of the packet page. Similarly, the pages within the packet are designed to prepare students for the successful completion of assignments of the Minds On Activities (and of course, quizzes and tests!). The mission and module that corresponds to any given think sheet is often linked within the PDF.

Think Sheets at The Curriculum Corner can be printed and distributed to classes and used as classwork. We have answer keys available for purchase by teachers only (we verify the identity of anyone who purchases answer keys before distributing them). Students can use the listed URLs of The Physics Classroom Tutorial to support them in the completion of the work. Some teachers may prefer to simply assign the readings from the Tutorials as homework and then use the Think Sheets during class as cooperative group activities or during guided practice sessions. However they are used, the pages in our Think Sheets are designed to lead students through an understanding of basic principles in a developmental manner. Questions on a given Think Sheet tend to build upon previous questions so that a conceptual understanding of the topic is gradually developed.

Solutions Guide Answer Key

If you're a teacher or homeschool parent, our Solutions Guide products are also available (for Physics and Chemistry) for teachers who would like to have PDF files with answers to all the questions on all the Physics or the Chemistry think sheets. These Solutions Guides are available as Digital Downloads, and each is only $25! And students - don't even think about it. We verify the purchaser is not a student before administering the downloads.
