In this video from the Institution of Engineering and Technology (IET), engineers explain the technology behind Wii controllers. Micro electro mechanical systems (MEMS) is the technology behind games console controllers and products like air bags. New applications for...

CK's job is helping people under the impact of the conflict ongoing in Yemen. In Yemen, he is managing a water and sewer programme which requires lots of engineering skill and also project management skill.

This video introduces Nariba, a graduate water engineer for engineering company Halcrow. Nariba performs assessments for construction projects, focusing on flood risk management. Her work includes water management, drainage, flooding, water quality issues, flood risk management and flood defences.

This resource, from Siemens UK, encourages students to appreciate the importance of clean water and the problems that may arise in the absence of it. Students consider soluble and insoluble pollutants and methods of filtration. They then explore contamination by microorganisms, water-borne diseases and the...

Comparing two sine waves of different amplitudes, this video shows that the intensity of a wave is proportional to the square of the amplitude.  The intensity is given I = ^P/_A, i.e., power per cross-sectional area.

This video summarises the properties of waves, i.e., reflection, refraction, diffraction and polarisation using a free App called Ripple free by Paul Falstad.  The App is very effective and versatile.
