## Conceptual Physics Course Package

We will be beginning a project during the 2024-25 school year in which we create a package of materials to support teachers teaching a Conceptual Physics course. The downloadable package will include slide decks, think sheets, labs, quizzes, and tests. Answer keys will be provided. This will be a for-sale item that is offered to teachers. We hope to have the project completed before the start of the 2025-26 school year.

In creating our Lesson Plans and Learning Outcomes for this course we have referenced several of the items that we intend to place in the package. We have used red text wherever we have made such a reference. These items will only be available by purchase of the course package.

## Electric Circuits

The lesson plans below include links to the specific resources on our website.

Teacher Guides for labs can be found here.

NOTE: All CalcPad problem sets are customized problem sets created specifically for this course. The links direct users to the Guest version. Task Tracker users should use the link on the Task Tracker page to the trackable CalcPad version.
