How do you work out how safe or dangerous a chemical or some other substance is? This week's Risk Bites takes a look at chemical safety, and estimating health risk from chemical exposure. This week's Risk Bites team: David Faulkner (post-production) Andrew Maynard (all the other stuff) Risk Bite
How do you know if the chemicals in the stuff you use and eat are safe? Only a small fraction of the thousands of chemicals in use today have been thoroughly tested for safety. Part of the problem is that how we test chemicals now is slow, expensive, and relies an awful lot on animal testing. How
Functions of graphs can be shifted and reflected. In this 2 part video we will look at horizontal and vertical, reflections and translations. Translations shift the functions. For vertical transformations, the transformation is applied to the whole function. Vertical translations shift the whole fun
Functions of graphs can be shifted and reflected. In this 2 part video we will look at horizontal and vertical, reflections and translations. VISIT us at www.fuseschool.org, where all of our videos are carefully organised into topics and specific orders, and to see what else we have on offer. Comm

Large stars die, and then explode into massive supernovae. This scatters all the elements of the periodic table throughout the Universe, which results in the third threshold of complexity -- the creation of chemical elements. Website: https://www.bighistoryproject.com/portal Facebook: https://www.f
The three types of a chemical reaction (analysis, synthesis and conversion) are only presented theoretically! An application and chemical experiments for this take place in the attendance phase at school! Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done b

Chemists always distinguish between the macroscopic and microscopic level. What does that mean? In the experiment zinc reacts with sulphur, this level is attempted to be demonstrated. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Learn the basics about Indicators, more specifically for acid and bases. An indicator is a large organic molecule that works somewhat like a " color dye". Find out more in this video! This Open Educational Resource is free of charge, under a Creative Commons License: Attribution-NonCommercial CC BY
