Play with a bar magnet and coils to learn about Faraday's law. Move a bar magnet near one or two coils to make a light bulb glow. View the magnetic field lines. A meter shows the direction and magnitude of the current. View the magnetic field lines or use a meter to show the direction and magnitude of the current. You can also play with electromagnets, generators and transformers!

Light a light bulb by waving a magnet. This demonstration of Faraday's Law shows you how to reduce your power bill at the expense of your grocery bill.

This lesson teaches students about editing films and respecting licensed materials, while also ensuring they receive the support they need to ensure completion of their films.

This lesson has students explore science content, decide on the topic for their film, and do all the preparatory work before filming begins.

In this lesson, students film interviews with content experts as well as additional B-roll footage, and film mentors help students find existing footage and media to supplement their films.

Lecture notes on the current and emerging varieties of financial technology, part 2

Technologies have profoundly transform the financial markets and in turn present new challenge to the financial education. For instance, as financial markets become more complex and generate more information, it also becomes more and more challenging for market participants to digest and manage the information overload. Upon completion of the course the students will develop a toolkit and will be conversant in current issues related to financial risk management including the dynamic market changes, new trends in financial analysis and a historical perspective on financial risk management.

This is a streamlined lesson for students to prepare for a Community Resilience Expo, focusing on flood.

Flowvis.org documents the course materials and student-created OER from the University of Colorado Boulder's Mechanical Engineering course on the physics and art of fluid flows. Students create and document images and videos of gases and liquids, and all work is published under a Creative Commons license. Lecture notes, lecture videos, course documents (syllabi, schedule, assignments) and the accompanying textbook are also published.

Explore pressure in the atmosphere and underwater. Reshape a pipe to see how it changes fluid flow speed. Experiment with a leaky water tower to see how the height and water level determine the water trajectory.

Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time. View a Free Body Diagram of all the forces (including gravitational and normal forces).

Learn how to make waves of all different shapes by adding up sines or cosines. Make waves in space and time and measure their wavelengths and periods. See how changing the amplitudes of different harmonics changes the waves. Compare different mathematical expressions for your waves.
