Virtual Labs The Virtual Lab is an online simulation of a chemistry lab. It is designed to help students link chemical computations with authentic laboratory chemistry. The lab allows students to select from hundreds of standard reagents (aqueous) and manipulate them in a manner resembling a real lab. Tackling the world’s challenges We are committed to ensuring that the chemical sciences contribute to their full potential to tackling the major global challenges of today and tomorrow. The world’s population is projected to reach 9 billion by 2050. The standard of living around the world has been rising, but socio-economic disparities remain. Individuals, communities, companies and nations all have a role to play in tackling inter-connected global challenges, in order to provide every person in every country with water, food, energy and a home, in an environmentally and economically sustainable way.

Chemistry — Cooler Than Absolute Zero! Here’s a look at the remarkable properties of ten of the periodic table’s elements. The first on our list was hailed as the philosophers’ stone when it was discovered. 1. Phosphorus Phosphorus was the first element ever isolated scientifically. In 1669 Hennig Brand evaporated water from urine, then allowed the residue to fester for a few months. Intuitor, How to Use Movie Physics in the Classroom How to Use Movie Physicsin the Classroom The Good, the Bad, and the Ugly Movie physics can provide a bonanza of enrichment activities for both high school physics students and first year physics students in college. These generally require nothing more than a VCR and stopwatch. Some movie scenes provide examples of good physics and others bad physics but all can be analyzed and used as topics of discussion.
50 Awesome Chemistry Videos For The Busy Science Teacher Though we don’t often recognize it, chemistry defines nearly every element of our everyday lives. From the reactions that fuel the sun to the biology of our bodies to the technology in our gadgets, chemistry is at the heart of everything we do and is the central science that unites biology, physics, geology, astronomy, medicine, and countless other fields. Yet chemistry doesn’t always get the credit and recognition it deserves for playing such an awesome role in, well, everything. If you’ve been slighting chemistry, there’s no better time to give the field the credit it deserves than National Chemistry Week. Founded in 1987, the week-long event has helped bring awareness to the role chemistry plays both in our lives today and in our future. You can get in the spirit of the event by checking out a few (or all) of these amazing chemistry videos online.
