How do you make sense of scientific models without falling into common traps? Here are three rules of thumb. This is part of a series of Risk Bites videos that tackle dose response and response models. This week's Risk Bites team: David Faulkner (post-production) Andrew Maynard (all the other stu
What is a scientific model and what is it good for? As a prelude to talking about dose-response models on Risk Bites, this week's video is a primer on models -- what they are, and why they are useful. This is part of a series of Risk Bites videos that tackle dose response and response models. Ch
Single, double and triple bonds are explained with the help of the spherical cloud model. This is another way to find Lewis formulas. Later, it can also be used to recognize the spatial structure of the molecules. Original: "Wolfgang Dukorn" Original: German. All translations in this video have be
Since stereoisoomerie is difficult to imagine, the principle of image and mirror image is explained with molecular models. The term enantiomer pair is also introduced. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
Bisphenol A - or BPA for short - is one of the more contentious chemicals on the block at the moment. Companies making BPA, and the products that contain it, claim that the substance is safe if used sensibly. But others aren't so sure. But before getting into the risks and benefits, it makes sens
Learn the basics about how metals are used, such as gold, copper, aluminium, steel. Where can we find these materials in our day to day world? Find out more in this video! Our teachers and animators come together to make fun & easy-to-understand videos in Chemistry, Biology, Physics, Maths & ICT.
There are many reasons to keep quiet. Sometimes it’s better to listen, or maybe you don’t want to draw attention to yourself. Your reasons can have a negative or positive impact. But what happens when you’re quiet for so long that you get used to it? These are the reasons why you are so used to bein
Learn how computer modeling indicates that supermassive black holes may exist at the centers of all galaxies in this video from NOVA: Black Hole Apocalypse. Use this resource to stimulate student curiosity about the structure of galaxies and to provide opportunities for students to develop and use m
A recent report from the Royal College of Obstetricians and Gynaecologists highlighted the challenges of dealing with potential but unproven risks to child health during pregnancy. While the report's authors acknowledge that most exposures to environmental chemicals experienced by pregnant women pr
What's the difference between a threshold dose response model, and a no-threshold model? And what are the limitations of each? This week Risk Bites tackles the basics of dose-response models. This week's Risk Bites team: David Faulkner (Animation concepts, editing, closed captions) Andrew Maynard
