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
Learn the basics about the law of constant composition and how to apply it. JOIN our platform at www.fuseschool.org This video is part of 'Chemistry for All' - a Chemistry Education project by our Charity Fuse Foundation - the organisation behind FuseSchool. These videos can be used in a flipped c
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
Learn the basics about balancing equations, as a part of chemical calculations. The law of conservation of mass states that no atoms are lost or made during a chemical reaction. There are different ways of arranging the atoms. Chemical reactions are about rearranging atoms. Chemical reactions can

In the introduction to functions video, we discovered what functions are, what domain and range mean and how to solve some problems. We saw that they could be called f(x) or g(x) or any letter. In this video, we’re going to look at composite functions - which makes use of different letters. VISIT
In this video, we will look at the state symbols (s), (l), (g), and (aq) and what they represent in a chemical equation. For equations to be complete, we must also include the state symbol for each reactant and product. There are four possible states, each with their own unique state symbol. So
