15 Fun Science Activities for Kids
We love fun science activities and science experiments. We have a whole list of fun ways to learn and explore today with your little scientist. These fantastic activities were inspired by Buggy and Buddy. 15 Fun Science Experiments for Kids 1.

BBC Bitesize - KS3 Chemistry - The periodic table - Revision 1
All the different elements are arranged in a chart called the periodic table . A Russian scientist called Dmitri Mendeleev produced one of the first practical periodic tables in the 19th century.
ACD/ChemSketch for Academic and Personal Use
ACD/ChemSketch Freeware is a drawing package that allows you to draw chemical structures including organics, organometallics, polymers, and Markush structures. It also includes features such as calculation of molecular properties (e.g., molecular weight, density, molar refractivity etc.), 2D and 3D structure cleaning and viewing, functionality for naming structures (fewer than 50 atoms and 3 rings), and prediction of logP. The freeware version of ChemSketch does not include all of the functionality of the commercial version. Visit ACD/ChemSketch to learn more about the commercial version. As an Educational Tool
Inertial reaction forces (discussed in "The Origin of Inertia") are a commonplace of everyday life. When we push on stuff, it pushes back because of its inertial mass. Less common in everyday life are pronounced recoil forces -- a special type of inertial reaction force -- like those experienced when shooting a gun or stepping out of a small boat onto a dock.

The course, based on promising results produced by the professional development model delivered in the Verizon Innovate Learning Schools, includes five modules developed around ISTE standards. Course modules are designed to help teachers, administrators and tech coaches implement effective mobile learning initiatives in their schools and classrooms. Continuing Education Units (CEUs) from Johns Hopkins University will be offered to teachers completing the Verizon Mobile Learning Academy courses. Mobile Learning (Mobile Devices, Apps,Tablets)
The Periodic Table's Endangered Elements
Click to enlarge We’re all familiar with the periodic table, but the majority of non-chemists probably aren’t familiar with the everyday uses of some of the many elements it contains. Some elements that many haven’t heard of find uses in technologies or applications we take for granted – but the supplies of these elements on Earth are not infinite. Today’s graphic, in a collaboration with the American Chemical Society’s Green Chemistry Institute, looks at some of the endangered elements in the periodic table, and why we might miss them when they’re gone.

The existence of transient mass fluctuations in objects subjected to large accelerations and rapid changes in acceleration depends upon "Mach's principle" and some peculiarities of "radiation reaction" forces. Mach's principle is the assertion that the physical origin of all inertial reaction forces is an interaction of the object with chiefly the most distant matter in the universe. (Inertial reaction forces are those things that push back on you when you push on stuff.)
Another one of my favorite teaching resources for all things science is The Periodic Table fo Videos, created and maintained by the University of Nottingham. Tables charting the chemical elements have been around since the 19th century - but this modern version has a short video about each one. It really brings the elements to L I F E. We've done all 118 - but our job's not finished. Now we're updating all the videos with new stories, better samples and bigger experiments. Plus they're making films about other areas of chemistry, latest news and occasional adventures away from the lab. They've also started a new series - The Molecular Videos - featuring their favourite molecules and compounds. All these videos are created by video journalist Brady Haran, featuring real working chemists from the University of Nottingham. by drsinasoul May 27
