In this predict-observe-explain activity, students explore different ways of extinguishing a flame with some surprising results. The lesson is introduced with the video of engineer Yusuf Muhammad. Yusuf is developing a revolutionary new household fire-safety device, incorporating the techniques of professional...

This video demonstrates how compressing a gas increases its temperature. A small piece of cotton wool is placed into the bottom of a narrow plastic tube. When the air is rapidly compressed by a piston, the air temperature increases and the cotton ignites. The 'fire piston' can be used to illustrates the transfer of...

Rory Hadden investigates how fires ignite, spread and how they can be extinguished. This research is then used to save lives by creating safer buildings for us to live and work in.

This video demonstrates how adiabatic compression of air can produce enough heat to ignite cotton wool.  The auto-ignition temperature of cotton wool is approximately 400⁰C.  The video could be used to explain the way diesel engines work.

These downloadable videos and animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to develop ideas relating to the distinction between combustion and decomposition in the...

These downloadable videos and animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to develop ideas relating to flames, from hydrogen to candle wax.

In this video, Matt describes how he became a fisheries technical officer for the Environment Agency. His job is to monitor river habitats and fish populations, including improving the habitat and restocking fish after any pollution incidents.

The video could be used to introduce units of work including...

Students work in teams to design and make a prototype device that can design and make a prototype of a simple device (to be sold in stores like B&Q) that will allow homeowners to remove water from their house during periods of flooding.

In this challenge the device will have to move 100ml of water from...

These videos highlight the problems caused by flooding in the developing world, and show how Practical Action works with local communities to help reduce the impact of future floo...
