From this video you should know the difference between interspecific and intraspecific, and that interactions can be positive, negative or neutral. Click here to see more videos: https://alugha.com/FuseSchool JOIN our platform at www.fuseschool.org These videos can be used in a flipped classroom
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
Van der Waals forces, dipole-dipole interactions and hydrogen bonds are explained. It is briefly repeated again how the polarity of molecules can be determined. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
This is part 2 for our videos on giant chemical structures. Part 1 is here: https://bit.ly/336zmMx Giant ionic structures also have exceptionally high melting points. This is because the electrostatic interactions between the ions are very strong. Mg2+ and O2- ions have double the number of cha
Learn the basics about the differences between different chemical structures, including giant covalent, giant ionic and metallic structures. There are numerous materials and substances that possess giant chemical structures. Some are common: like the grains of sand on the beach; the microprocessors

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
Ecosystems are large, often highly complex areas of our environment. In this video we learn how abiotic and biotic factors interact with one another in a ecosystem, how trophic levels work, and how various factors in an ecosystem lead to evolution of species through different selection pressures.
