You may well be watching this video through a thin layer of Indium. 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.
Students use a simple set up consisting of a coil of wire and a magnet to visualize induced EMF. First, students move a coil of wire near a magnet and observe the voltage that results. They then experiment with moving the wire, magnet, and a second, current carrying coil. Students connect the coil to a circuit and the current from the induced EMF charges a conductor.
The video resource "Induction - An Introduction: Crash Course Physics #34" 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.
Paul Andersen explains how inertial mass is defined and measured. When a force is applied to an object or a system it will accelerate. Using Newton's Second Law of Motion (F=ma) you can calculate the inertial mass.
Hoofdpunten: De cursus geeft een kennismaking met infrastructuur voor Watermanagement. Voor Waterbeheer ligt de focus op ontwatering, afwatering, wateraanvoer en het ontwerpen van eenvoudige aan- en afvoersystemen. Voor Civiele gezondheidstechniek ligt de focus op Gezondheidstechniek en volksgezondheid, drinkwatervoorziening en Integraal waterbeheer. Leerdoelen: Begrip van basisopzet infrastructuur Watermanagement. Eenvoudige systemen kunnen ontwerpen.
Student teams design, build and test small-sized gliders to maximize flight distance and an aerodynamic ratio, applying their knowledge of fluid dynamics to its role in flight. Students experience the entire engineering design process, from brainstorming to CAD (or by hand) drafting, including researching (physics of aerodynamics and glider components that take advantage of that science), creating materials lists, constructing, testing and evaluating—all within constraints (works with a launcher, budget limitation, maximizing flight distance to mass ratio), and concluding with a summary final report. Numerous handouts and rubrics are provided.
The video resource "Integrals: Crash Course Physics #3" is included in the "Sociology" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.
The lectures introduce a number of topics that are important for IWRM and the modeling exercise. The lectures introduce water management issues in the Netherlands, Rhine Basin, and Volta Basin. The role-play is meant to experience some of the social processes that, together with technical knowledge, determine water management.
The City of Ann Arbor recognized stormwater runoff as a growing threat to the quality of their water supply. They're addressing the issue with two complementary strategies.
In this video, we become familiar with integrals, both by understanding them as sums of areas under plots of functions, and by understanding them as anti-derivatives. We present the u-substitution rule, which is the analog of the chain rule for differentiating composite functions.
Paul Andersen explains how forces on an object always require another object. An object cannot exert a force on itself. If net forces on an object are balanced the object will remain at rest or move with a constant velocity.
Paul Andersen explains how constructive and destructive interference can create interference patterns. Interference patterns can be created by all types of waves, including water, sound, and light. A classic experiment that demonstrates interference patterns is the monochromatic double slit experiment.

In this video Paul Andersen explains how intermolecular forces differ from intramolecular forces. He then explains how differences in these forces account for different properties in solid, liquids and gases. Some of these properties include the boiling point, melting point, surface tension, capillary action and miscibility.
In this video Paul Andersen explains the importance of intermolecular forces in chemistry. Intermolecular forces exist between dipoles (like hydrogen bonds), between dipoles and induced dipoles (like Ar and HCl) and between induced dipoles. The energy of the force is based on the size of the molecule and the number of electrons.
Paul Andersen explains how the internal energy of a system can change as the internal structure of the system changes. An object model will not be able to account for the restoring forces and so a system model must be used.
Are you participating in an internship or supervising someone who is? If so, take a minute to explore this course that accompanies an internship for the Bachelor's degree in Energy Sustainability and Policy. This course provides students opportunities to creatively reflect on their experiences as well as opportunities to prepare for a job search. Job search preparation is done via a SWOT analysis, resume writing, and a mock interview.
After watching a 1940 film clip of the "Galloping Gertie" bridge collapse and a teacher demo with a simple pendulum, student groups discuss and then research the idea of motion that repeats itself specifically the concepts of periodic and harmonic motion. They become aware of where and how these types of motion occur and affect them in everyday applications, both natural (seasons, tides, waves) and engineered (swings, clocks, mechanical systems). They learn the basic properties of this type of motion (period, amplitude, frequency) and how the rearrangement of the simple pendulum equation can be used to solve for gravitational acceleration, pendulum length and gravity. At lesson end, students are ready to conduct the associated activity during which they conduct experiments that utilize swinging Android® devices as pendulums.
This course provides an introduction to the universe beyond the Earth. We begin with a study of the night sky and the history of the science of astronomy. We then explore the various objects seen in the cosmos including the solar system, stars, galaxies, and the evolution of the universe itself. As an online course, it is equivalent to 6 lecture hours, and satisfies science requirements for the AA and AS degree. It is designed to be thorough enough to prepare you for more advanced work, while presenting the concepts to non-majors in a way that is meaningful and not overwhelming. We will consider the course a success if you have learned how to think about the universe critically in an organized, logical way, and to have enhanced your appreciation of the sky around us.
Microcontrollers are the brains of the electronic world, but in order to play with one, you must first get it connected! For this maker challenge, students learn how to connect their Arduino microcontroller circuit boards to computers. First, students are walked through the connection process, helped to troubleshoot common pitfalls, and write their first Arduino programs (setup and loop functions, semicolons, camel case, pin 13 LED). Then they are given the open-ended challenge to create their own blinking LED code—such as writing Morse code messages and mimicking the rhythm of a heartbeat. This practice helps students become comfortable with the fundamental commands before progressing to more difficult programs.
