I'm sure you've heard of Isaac Newton and maybe of some of his laws. Like, that thing about "equal and opposite reactions" and such. But what do his laws mean? And how do they help us understand the world around us? (11:04)

Lesson ObjectiveStudents duplicate a "magic trick" and explain the science behind it. Questions to ConsiderWhy does Mr. Haigh first demonstrate but not explain the lab?Notice how the lab requires students to apply their knowledge of science to a novel taskWhat do students learn about pressure and density as it applies to liquids and gases?

This video uses balancing on a unicycle as an example to explain net force (mass x acceleration). It explains how all of the outside forces, such as gravity, contact force, and friction help to create balance when riding a unicycle. It also explains counter-steering to move the point of contact and control the direction of the unicycle. (4:32)

Magnetically levitated trains are common nowadays. However, the MagLev train the Central Japan Railway Company developed is quite unique and superior to the other trains. Running at more than 600 km per hour, it has achieved the status of ‘fastest train.’ This train uses superconducting magnets, which is why it is called SC MagLev. Once charged with an exciting current, the superconducting magnets of this train produce a circulating DC current and strong magnetic field forever, with zero loss. (11:33)
