The video resource "Ampère's Law: Crash Course Physics #33" is included in the "Media Literacy" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

There are no published textbooks on laboratory techniques in the geosciences at the undergraduate level. This project is creating learning modules on scientific analysis and analytical methods that will be delivered in a blended learning format.

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.

Paul Andersen explains how the change in angular momentum is equal to the torque applied over a given time. A sample problem and inquiry activity are included.

Paul Andersen explains rotating object have angular momentum. The angular momentum of a point object is the product of the distant from the center of rotation and the linear momentum. The angular momentum of an extended object is a product of the rotational inertia and the angular velocity.

Paul Andersen explains that the angular momentum of a system will be conserved as long as there is no net external torque. Both point objects and extended objects are covered along with several examples.

Paul Andersen explains how the angular momentum of a system can be calculated by determining the angular momentum of all individual objects within the system. An inquiry activity using a gyroscope is also included.

The video resource "The Anthropocene and the Near Future: Crash Course Big History #9" is included in the "Big History" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

Antimatter, the charge reversed equivalent of matter, has captured the imaginations of science fiction fans for years as a perfectly efficient form of energy. While normal matter consists of atoms with negatively charged electrons orbiting positively charged nuclei, antimatter consists of positively charged positrons orbiting negatively charged anti-nuclei. When antimatter and matter meet, both substances are annihilated, creating massive amounts of energy. Instances in which antimatter is portrayed in science fiction stories (such as Star Trek) are examined, including their purposes (fuel source, weapons, alternate universes) and properties. Students compare and contrast matter and antimatter, learn how antimatter can be used as a form of energy, and consider potential engineering applications for antimatter.

Antimony is element number 51 and its chemical symbol is Sb. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

This free electrical engineering/technology textbook provides a series of chapters covering electricity and electronics. The information provided is great for students, makers, and professionals who are looking for an application-centric coverage of this field.

Aqua Regia is a special combination of two acids which can dissolve gold.

Students are introduced to Pascal's law, Archimedes' principle and Bernoulli's principle. Fundamental definitions, equations, practice problems and engineering applications are supplied. A PowerPoint® presentation, practice problems and grading rubric are provided.

Are you alone? To answer this question we have to take a look what "you" are first. What are you made of and where you stand in this universe. Are you your body? Your atoms? And how are your parts connected to the big picture? The video "Are You Alone? (In The Universe)" is a resource included in the Space sciences topic made available from the Kurzgesagt open educational resource series.

Argon, an inert noble gas, is element number 18. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.
