Introduce the point that odds predict the most likely event to occur, unless there is some special factor preventing it, eg sportsman taking drugs, cheating on the lottery, stopping smoking, a football team getting a better coach or players etc.

What is a chemical reaction? - BBC Bitesize

Informal peer and self assessment is inherent throughout the group discussions (that promote listening, discussion and development of coherent ideas), the role play (that requires team working and cooperation), the demonstrations and the plenaries (when teacher questioning and review are essential). Andrew Burrows, John Holman, Simon Lancaster, Tina Overton, Andrew Parsons, Gwen Pilling, Gareth Price Many useful chemical reactions involve burning fuels to release energy. These reactions heat our homes, power our cars and generate lots of the electricity that we use. Chemical reactions can result in a change in temperature. Exothermic and endothermic reactions (and changes of state). As the temperature falls, the water will freeze so the beaker can be lifted with the mat underneath.Exciting and entertaining chemical reactions pique interest in science. These types of demonstrations encourage people to ask questions and may lead them into science-related careers. A few years ago I read ‘Surely You’re Joking, Mr Feynman’, and since then fell in love with Feynman’s style of teaching physics. ‘QED: A Strange Theory’ is a semi-technical book in which Feynman discusses the physics substantively rather than just talking about physics as a discipline. Just to clarify, I have no complaint whatsoever with him talking about physics from a more ‘meta’ point of view, as was done in ‘The Character of Physical Law’. I read the book, and loved it. He doesn’t sacrifice any of his characteristic charm, while still explaining the counterintuitive theory. This book was transcribed from a series of lectures ( available on youtube), so is naturally quite verbose. The Feynman Lectures on Physics Fortunately, this reaction is nonspontaneous at normal temperatures and pressures, it is a highly endothermic reaction. However, nitrogen monoxide is capable of being produced at very high temperatures, and this reaction has been observed to occur as a result of lightning strikes. Chemical reactions help us understand the properties of matter. By studying the way a sample interacts with other matter, we can learn its chemical properties. These properties can be used to identify an unknown specimen or to predict how different types of matter might react with each other.

Unique unified approach helps the reader to see the connections between different ideas and concepts across the traditional divisions of chemistry My research interests have been in the area of high-resolution nuclear magnetic resonance (NMR) spectroscopy, particularly in the development and application of new techniques. Some of our publications and associated software, as well as older lecture notes from various NMR summer schools, are available on the group web server. understand that, since some endothermic reactions can occur at room temperature, enthalpy changes alone do not control whether reactions occur Entropy increases when a substance is broken up into multiple parts. The process of dissolving increases entropy because the solute particles become separated from one another when a solution is formed. So far I’ve only done a few chapters of volume 1. I really intended to work through it in its totality at one stage, but I realised that I should use my time before university to learn things other than physics.Assessment for Learning is an effective way of actively involving students in their learning. Each session plan comes with suggestions about how to organise activities and worksheets that may be used with students.
