We look at how the mass of wire wool changes when it is burned. Wire wool is almost 99% iron. When we burn it, it combines chemically with oxygen from the air to form iron(III) oxide. The mass of the product is more than the mass of the...

We investigate the properties of two types of gas bubbles: methane gas bubbles and bubbles of the gas we breathe out. The air-filled bubbles sink and we are unable to set them alight, while the methane bubbles float upwards and are...

We use magnesium and blocks of dry ice to show how a redox reaction occurs. A cavity in a block of dry ice is filled with coils of magnesium ribbon, which are set alight. A second block is then placed on top, but instead of this putting...

In this video, we discuss how gas exchange occurs across the respiratory membrane at the alveoli and how this involves Type I Alveolar Cells.

Dubbed the world’s most powerful tidal turbine, the device is the size of a jumbo jet and can produce enough power to supply electricity to 2,000 U.K. homes. <br/>
