Explore what it means for a mathematical statement to be balanced or unbalanced by interacting with objects on a balance. Discover the rules for keeping it balanced. Collect stars by playing the game!

Learn about graphing polynomials. The shape of the curve changes as the constants are adjusted. View the curves for the individual terms (e.g. y=bx ) to see how they add to generate the polynomial curve.

Explore size estimation in one, two and three dimensions! Multiple levels of difficulty allow for progressive skill improvement.

In this activity, students use authentic Arctic climate data to explore albedo and its relationship to seasonal snowmelt as a self-reinforcing feedback mechanism, which is then applied to large scale global climate change.

This activity introduces students to the Arctic and Arctic climate. Through a virtual exploration of the geography of the Arctic students become familiar with the region. They are then introduced to meteorological parameters that Arctic research teams use.

In this middle school and high school unit, students compare and constrast Arctic expeditions of the past (1893-1896 Fram expedition) and the present (2019-2020 MOSAiC expedition) to prepare for the Arctic of the future.

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.

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).
