Lab:List of intermediate level Practical Chemistry experiments - Learn Chemistry Wiki From Learn Chemistry Wiki These experiments are for students who have already been introduced to basic chemical concepts. Students' ages will vary in different countries. In the UK they will generally be aged 14 to 16. They are organized by topic.

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. But how does this process work, and why do you need to bend the glow stick to initiate it? 10 Benefits of Rising Early, and How to Do It “Early to bed and early to rise makes a man healthy, wealthy and wise” – Ben Franklin, famously “Put no trust in the benefits to accrue from early rising, as set forth by the infatuated Franklin …” – Mark Twain By Leo Babauta Building a Business The Course Please note this course is now FULL.

Chem Lectures Menu .... Metric Download "Formula Club & Practice Blitzes" in the Summer Assignment Page. We shall next do Unit 6, Equations, here and follow it with unit 5. Unit 6 Equations ..... 50 Tips for College Students I did the "extended tour" of college. From about 1991-2002. I did get 4 degrees, so at least I have an excuse. :) I've also been an adjunct professor, so I've also been at the other side of the classroom. 1) The Freshman Fifteen does exist.

Business Model Generation - Canvas Using the Business Model Generation Tools There have been some questions posted lately asking for guidance in using the tools associated with the Business Model Generation approach - the Business Model Canvas and the Value Proposition Canvas. Though the Business Model Canvas was released under Creative Commons and the Value Proposition Canvas under copyright, the requirements for use of the two tools are really quite similar. IB Physics: Activities In line with the approaches to teaching and learning I am moving to a more student centred approach. Instead of me standing by the board asking questions the students now sit by their computers and ask me questions. To this end I have started to produce a series of activity worksheets that combine observation, measurement, theory, simulation and problem solving for each component of the course. Each activity lasts just over an hour with extension work if required. As with the whole of this website IT'S AN ONGOING PROJECT so they are a bit rough and ready, however my students are doing a good job of spotting mistakes and pointing out bits that are difficult to follow and I'm doing a good job of correcting them :-).

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. As long as the solution is basic (alkaline), it will be blue. Avner Dorman Avner Dorman ( Hebrew : אבנר דורמן) (born April 14, 1975 in Tel Aviv , Israel ) is an Israeli-born composer of contemporary classical music. Biography [ edit ] Avner Dorman holds a Doctorate in Music Composition from the Juilliard School [ 1 ] where he studied as a C.V. Starr fellow with John Corigliano . [ 2 ] He completed his Master’s degree at Tel Aviv University (where he majored in music , musicology , and physics ) studying with former Soviet composer Josef Bardanashvili . [ 3 ] At age 25, Avner Dorman became the youngest composer to ever win Israel's prestigious Prime-Minister's award. Since, he has been awarded the " ACUM " prize from the Israeli performing rights society for his Ellef Symphony. [ 4 ] Ma’ariv , the second largest newspaper in Israel, named Dorman “Composer of the Year” for 2002, [ 5 ] and the performance of his song cycle Boaz received the Israeli Cultural Ministry Prize for best performance of Israeli music the same year.

The Spread of Inequality The causes of socioeconomic inequality have been debated since the time of Plato. Many reasons for the development of stratification have been proposed, from the need for hierarchical control over large-scale irrigation systems to the accumulation of small differences in wealth over time via inheritance processes. However, none of these explains how unequal societies came to completely displace egalitarian cultural norms over time.

Une gigantesque base de données gratuite fournie par la société royale de chimie. On peut y retrouver toutes les caractéristiques et publications pour des millions de molécules. Ce serait un outil très utile pour les étudiants au les étudiants au cégep ou à l'université pour la préparation des laboratoires ou pour mener des projets (comme dans le cours d'intégration), notamment en chimie organique. by romainmartiny Feb 26
