ScienceGeek.net I re-organized the course during the 2014 - 2015 school year. Some review activities were moved to new units. This has resulted in a change to some of the file names, so direct links to the individual activities may need to be changed. These are not graded assignments. They are intended only as practice of concepts and vocabulary that are essential to your success in this course. The Chemistry of Glow Sticks Click to enlarge Everyone’s familiar with glow sticks, but it’s likely that fewer are familiar with the chemistry behind their glow. You may have wondered what happens when you snap a glow stick to activate it; by doing this, you’re actually kicking off a chemical process that eventually leads to the production of the coloured light.

Chemistry resources for Teachers and Students Search over 2000 substance pages for compound structures, properties, spectra, and more. Teaching analytical chemistry? Spectraschool is a great place to start. For lesson starters, try interactive Gridlocks, or our Starters for Ten puzzles. IB Chemistry revision notes and syllabus Assessment in the Diploma Program (2016) Assessment is by means of examination and practical for both higher and standard level chemistry courses. Examination weighting - 80% Internal assessment weighting - 20% Examination (higher level) There are three papers:

The effect of temperature on rates of reaction You can mark the position of activation energy on a Maxwell-Boltzmann distribution to get a diagram like this: Only those particles represented by the area to the right of the activation energy will react when they collide. The great majority don't have enough energy, and will simply bounce apart. The Mystery of Matter: Search for the Elements About the Program The Mystery of Matter: Search for the Elements is an exciting series about one of the great adventures in the history of science: the long and continuing quest to understand what the world is made of. Three episodes tell the story of seven of history’s most important scientists as they seek to identify, understand and organize the basic building blocks of matter. The Mystery of Matter: Search for the Elements shows us not only what these scientific explorers discovered but also how, using actors to reveal the creative process through the scientists’ own words and conveying their landmark discoveries through re-enactments shot with replicas of their original lab equipment. Knitting these strands together is host Michael Emerson, a two-time Emmy Award-winning actor. Meet Joseph Priestley and Antoine Lavoisier, whose discovery of oxygen led to the modern science of chemistry, and Humphry Davy, who made electricity a powerful new tool in the search for elements.

Chemistry - Annenburg Foundation Unit Overview Since the first time early humans lit a fire, cooked food, fermented fruit, or flaked a stone axe, we have been manipulating the matter around us. This unit explores how chemistry evolved from adapting materials for practical purposes to a science that systematically offers solutions to the world's challenges. It is a story that will start with Democritus around 400 BCE, taking us through the early Arab chemist, Jābir ibn Hayyān, to the meticulous work of the Middle Age alchemists, and finally to the birth of chemistry as a science during the Age of Enlightenment in the 18th century. In the accompanying video, we explore the Silicon Age, where the goal of manipulating and purifying matter at the atomic scale is making possible today's technological advances such as cell phones and solar panels.

What makes disappearing ink disappear? Carbon dioxide. A common type of disappearing ink is based on an acid-base indicator called thymolphthalein. This is a molecule that absorbs visible light when it is in an alkaline solution, and becomes colorless in a neutral or acidic solution. Thymophthalein To turn it into a blue ink, we add sodium hydroxide (lye), a strong alkali.

‘Compound Interest’ is a blog producing easy-to-understand graphics on a variety of chemistry topics, focusing particularly on the chemistry we come across on an everyday basis. Compound Interest is the creation of Andy Brunning, a chemistry teacher based in the UK. by svt_liep Aug 23
