For some, it is a hobby; for others it is a microbusiness venture. For still others, it is a way of life and livelihood, employing a full staff of artisans. If you talk to people who make soap, you find a number of common threads. The most marked is what is called “the addiction.” It appears that once a person has made soap, there is no turning back. Soapmaking is fun. Creative Chemistry - fun activities, worksheets, games and revision quizzes. Nmrdb.org. AIST:RIO-DB Spectral Database for Organic Compounds,SDBS.

Chemistry Experiments and Demonstrations. Home - Practical Chemistry. This website is for teachers of chemistry in schools and colleges.
It is a collection of experiments that demonstrate a wide range of chemical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Chemistry is a practical science. Chemistry Demonstrations, Experiments, Labs & Projects. These are tutorials for performing your own chemistry demonstrations, laboratory exercises, projects, and chemistry experiments.
Photos and movies are available for some chemistry demos. Chemistry Laboratory Safety RulesMake your chemistry laboratory experience safe by following these simple rules. How to Write a Lab ReportLab reports are an essential part of all laboratory courses and usually a significant part of your grade. If your instructor gives you an outline for how to write a lab report, use that. Here's a format for a lab report you can use if you aren't sure what to write or need an explanation of what to include in the different parts of the report. Free labs! Chemistry Labs.

Application of the Scientific Method. Chemistry Laboratory. Microscale Gas Chemistry. Our Gas Reaction Catalyst Tube can be used to demonstrate a variety of gas phase chemical reactions. The catalyst contains a layer of disbursed palladium atoms on a ceramic material and enclosed within a glass housing as per the fugure. Hydrogenation of alkenes occurs at very temperatures (even < 0 deg C). A wonderful classroom demonstration shows how a catalytic converter works by transforming CH4 (or any hydrocarbon) + NO2 (the reddish mixture in the left syringe below) into N2 + H2O + CO2 (right syringe - condensation droplets of water are often noticed in right syringe).
Gas Bags For classroom use, gases can be prepared and stored in sealable plastic food bags equipped with a dispensing tube. Mini-Ozone Generator Ozone is generated for in situ use. Left: Apparatus dispensing O3 to a flask. Podcast Archive: Chemistry of Innovations. News - Chemistry Now. The National Science Foundation (NSF) has joined forces with NBC Learn and the National Science Teachers Association (NSTA) to celebrate the International Year of Chemistry by creating "Chemistry Now"--a weekly, online video series that uncovers and explains the science of common, physical objects in our world and the changes they undergo every day.
The series also looks at the lives and work of scientists on the frontiers of the 21st century... More. Chemistry. Explore.

Ascalaph is a general purpose molecular modeling software that performs quantum mechanics calculations for initial molecular model development, molecular mechanics and dynamics simulations in the gas or in condensed phase.
It can interact with external molecular modeling packages (MDynaMix, NWChem, CP2K, PC GAMESS/Firefly and DelPhi). Learn more about Ascalaph Packages Download Abalone is designed for macromolecular simulations (proteins, DNA). It supports both explicit and implicit solvent models. In contrast to Ascalaph, tailored to the simulation of small molecules, Abalone is focused on molecular dynamics modeling of biopolymers. Learn more about Abalone Tutor Purchase. Chemistry Freeware.

Works for making outlines for basic lab quite well, just skip evaluation note (like one in winrar, but may cut off) and blank lab by canceling setting in lab wizard then desired. Also possibility to include more chemicals otherwise than just writing to label by filling up the info. but for more freely work try out acd free labs or text editors add-on packades or pen and paper ;). also fairly good after adjusting (label wriring) is virtual lab from chemcollective. – simo88
