Alcohol is a naturally occurring poison. What are the risks and health problems people can suffer from alcohol use or abuse? Biology - Healthy Living - Alcohol is a toxin and is produced by fermenting yeast. Alcohol damages both the...

Esters occur in nature and have been harnessed by the perfume industry. What are esters and how are they made and used? Chemistry - Chemical Industries - Learning Points. Esters give many fruits their scents, including bananas, lavender...

We put three different plants under different conditions to demonstrate that both light and carbon dioxide are needed for photosynthesis to occur. A leaf from each plant is taken and heated in ethanol to remove the pigment. These are...

We investigate the amount of energy stored in maize snacks and peanuts by burning them. The food is placed under an aluminium beaker of water before being set alight and the temperature change of the water is recorded. We can compare the...

We extract the DNA from a kiwi fruit by mashing it with detergent liquid, salt and water. The mixture is then filtered and incubated before a layer of chilled ethanol is added. The jelly-like DNA can then be extracted. Biology - Cells...

Discover the chemical process which produces some of our most common foodstuffs, from bread to yoghurt, to wine and vinegar. Chemistry - Chemical Industries - Learning Points. Fermentation is the process of converting sugar and other...

Functional isomerism occurs when compounds with the same molecular formula have different functional groups. For instance, ethanol (an alcohol) and dimethyl ether (an ether) share the formula 𝐶2𝐻6𝑂C2H6O but differ in their functional...

This video discusses the use of plant material for biofuel production as a way to reduce carbon emissions and combat climate change. It highlights the importance of finding alternative plant sources that do not compete with food crops...

This video is answering the question of what are biofuels made of.

Dr. Forrester explains how thermometers and anemometers help provide information about the weather.

The video explores the evolution of motor vehicles in response to dwindling petroleum reserves and environmental concerns. It showcases innovative designs such as the Tesla Roadster, Toyota Prius plug-in hybrid, and vehicles powered by...
