These exercises cover the Science Practices for Advanced Placement Biology. They were written by Julie Zedalis and John Eggebrecht, and include alignment information to the College Board AP Biology Course and Exam Description. The exercises are also available directly in the OpenStax AP Biology textbook.

This group activity engages students in the calculation of absorption spectra. It is appropriate for any course covering the baseline mathematical concepts of atomic spectra, including chemistry, physics, astronomy, and related courses.

For the Principles of Accounting: Volume 2 Managerial Accounting, this video focuses on Chapter 6 (Activity Based Costing) using the Musicality, Inc. problem, exploring the calculations differences between Single Plantwide Overhead rate vs. Activity Based Costing. Covering the cost per unit / gross profit per unit only.

This lesson is a lab in which students use thermometers, white and dark paper, and lamps to measure differences in albedo between the light and dark materials. Connections are made to albedo in Antarctica.

This activity by Lauren Roberts guides students through the process of finding, vetting, summarizing, and citing a scientific article. Professor Roberts is from South Mountain Community College in Arizona's Maricopa Community College District.

This file contains two activities created by Robert Wagner of Harrisburg Area Community College. The Scientific Article Assignment provides a framework for students to analyze and interpret a level-appropriate scientific article. The Solar Observation project guides students through a more extensive observation activity, and includes a setup for data recording and reporting.

Students will draw out a multi-step process and add captions based on OpenStax Biology - Chapter 5 - Structure and Function of Plasma Membranes section 5.4 (bulk transport). This activity is authored by Sara Milillo, Director of Math and Science, Bay Path University.

This module covering Membrane Transport was written by Dr. Karla Fuller from Guttman Community College of CUNY. The module contains files covering the learning objectives, demonstrations, assessments, think-pair-share, and more.

This activity features calculations and rankings as well as student evaluations of their understanding. Instructions are provided on the document, which is ready for distribution to students. It was developed by Celestina A. Pangan and Madhu Gyawali.

This collection includes lesson plans, student activities, and clicker/discussion questions, all on the subject of gas properties in Chemistry. They were authored by Kerriann Reynolds from Plymouth State University.

These reading guides for OpenStax College Physics cover the chapters most often taught in the first semester. They are organized by chapter and section. The guides include chapter summaries, core terminology and equations, and review questions.

This set of three activities were written by Sophie Haci and Rachel Polukuri of Houston Community College. They cover demand change, minimum wage, and opportunity cost.

This brief instructor-facilitated activity asks students to observe a simple demonstration, record their observations, and apply their knowledge to other conditions. It was written by Johnathan Hugh Broome from University of Southern Mississippi.

This free, illustrated book features instructions and information for how to use your smartphone to take photographs of the night sky and numerous astronomical objects. .

These Interactive Physics Demonstrations were developed by MAJ James Bowen, MAJ Cathleen Barker, MAJ Andrew Wilhelm, and others at the United States Military Academy for their University Physics course. Each activity is presented as a worksheet, which guides students through an experimental or observational process with questions.

We are constantly bombarded by information, and finding a way to filter that information in an objective way is crucial to surviving this onslaught with your sanity intact. This is what statistics, and logic we use in it, enables us to do. Through the lens of statistics, we learn to find the signal hidden in the noise when it is there and to know when an apparent trend or pattern is really just randomness. The study of statistics involves math and relies upon calculations of numbers. But it also relies heavily on how the numbers are chosen and how the statistics are interpreted.

This work was created as part of the University of Missouri’s Affordable and Open Access Educational Resources Initiative (https://www.umsystem.edu/ums/aa/oer). The contents of this work have been adapted from the following Open Access Resources: Online Statistics Education: A Multimedia Course of Study (http://onlinestatbook.com/). Project Leader: David M. Lane, Rice University. Changes to the original works were made by Dr. Garett C. Foster in the Department of Psychological Sciences to tailor the text to fit the needs of the introductory statistics course for psychology majors at the University of Missouri – St. Louis. Materials from the original sources have been combined, reorganized, and added to by the current author, and any conceptual, mathematical, or typographical errors are the responsibility of the current author.

This Introductory Chemistry textbook was developed by the Chemistry faculty at Montgomery College, and provided by Professor Patricia Takahara. The book is meant for students with very little or no background in chemistry. Concepts here are presented at a very basic level in order to provide the foundation for college-level general chemistry. This book is used in Introductory Chemistry, a non-credit, preparatory course at Montgomery College (Maryland).

These Guided Notes are note-taking frameworks for Macroeconomics, corresponding to OpenStax Macroeconomics 2e (or the corresponding chapters of OpenStax Principles of Economics). They contain the structure for students to actively engage with the material while in lecture or while reading.

The notes were authored by Kevin Cook of Des Moines Area Community College.

This activity is designed to help students understand the representation of Maslow's Hierarchy of Needs in everyday communications. Students will first read about the concept, then explore a familiar environment -- Twitter -- for expressions of it. (The activity can be adapted quickly for use with other social media applications and communication sites.) This activity was created by Dr. Sally B. Seraphin, University of Tennessee-Knoxville.
