The history of medicine is about two of our big questions: one, what is life? What makes it so special, so fragile, so… goopy!? Two, how do we know what we know? Why should I take my doctor’s advice? Why are deep-fried Oreos bad for me? It may be tempting to look at medicine as a science that has simply progressed over time—that medicine used to be bad, and its history is a story of how it got better.

This open course with a new set of ancillary materials for OpenStax Chemistry was created under a Round Eleven Mini-Grant for Ancillary Materials Creation and Revision. The materials created in order to support faculty implementing OpenStax Psychology in the classroom include:
Lecture Slides Chapter Checklists Practice Problems Newly-Created Videos
Along with these resources, the open course also contains a laboratory section with new instructional videos, a laboratory notebook and a sample notebook with responses, and experiments for each course.
Students prepare for the associated activity in which they investigate acceleration by …
Students prepare for the associated activity in which they investigate acceleration by collecting acceleration vs. time data using the accelerometer of a sliding Android device. Based on the experimental set-up for the activity, students form hypotheses about the acceleration of the device. Students will investigate how the force on the device changes according to Newton's Second Law. Different types of acceleration, including average, instantaneous and constant acceleration, are introduced. Acceleration and force is described mathematically and in terms of processes and applications.

Students investigate the motion of a simple pendulum through direct observation and data collection using Android® devices. First, student groups create pendulums that hang from the classroom ceiling, using Android smartphones or tablets as the bobs, taking advantage of their built-in accelerometers. With the Android devices loaded with the (provided) AccelDataCapture app, groups explore the periodic motion of the pendulums, changing variables (amplitude, mass, length) to see what happens, by visual observation and via the app-generated graphs. Then teams conduct formal experiments to alter one variable while keeping all other parameters constant, performing numerous trials, identifying independent/dependent variables, collecting data and using the simple pendulum equation. Through these experiments, students investigate how pendulums move and the changing forces they experience, better understanding the relationship between a pendulum's motion and its amplitude, length and mass. They analyze the data, either on paper or by importing into a spreadsheet application. As an extension, students may also develop their own algorithms in a provided App Inventor framework in order to automatically note the time of each period.

Students will learn about the Transit of Venus through reading a NASA press release and viewing a NASA eClips video that describes several ways to observe transits. Then students will study angular measurement by learning about parallax and how astronomers use this geometric effect to determine the distance to Venus during a Transit of Venus. This activity is part of the Space Math multimedia modules that integrate NASA press releases, NASA archival video, and mathematics problems targeted at specific math standards commonly encountered in middle school textbooks. The modules cover specific math topics at multiple levels of difficulty with real-world data and use the 5E instructional sequence.

After using the historical development of concepts of conserved motion to develop introductory understanding, students are directed to a series of activities to gain a better understanding of momentum, conservation of momenta, angular momentum, and conservation of angular momenta.
In uniform circular motion, angular velocity (𝒘) is a vector quantity and …
In uniform circular motion, angular velocity (𝒘) is a vector quantity and is equal to the angular displacement (Δ𝚹, a vector quantity) divided by the change in time (Δ𝐭). Speed is equal to the arc length traveled (S) divided by the change in time (Δ𝐭), which is also equal to |𝒘|R. And arc length (S) is equal to the absolute value of the angular displacement (|Δ𝚹|) times the radius (R).

Explore the physics and material science of making stone tools. Educator Nate Salzman walks us through the surprisingly complex science of flintknapping, or the process of turning stone into blades, arrowheads, spear points, axes, jewelry and more. Making tools from stone may be thousands of years old, but required people to think about the properties of the material they were using and the physics of striking the stone to shape it just right.NOTE: These are animations derived from the video "The Science of Knapping" which is linked here and published under its own listing on OER Commons.This resource is part of Jefferson Patterson Park and Museum’s open educational resources project to provide history, ecology, archaeology, and conservation resources related to our 560 acre public park.
