All about engines

What does 'horsepower' really mean? And how do engines work? Join Luke and Abhi from MIT to find out! As Abhi explains, engines produce power by forcing a mixture of fuel and air into a tight space and then burning it. Piston engines and turbine engines do this in similar, yet different ways. After watching this video, ...

Heat changes everything

In this learning sequence, students explore a simple particle model for matter, heat energy and thermal expansion. They apply their learning to the context of expansion and contraction of rail lines and investigate ways that this is mitigated in real situations involving rail lines. They subsequently explain this to young ...
