Beautiful Reactions Precipitation Chemical Garden Color Change Metal Displacement The science of snowflakes - Maruša Bradač The phrase “no two snowflakes are alike” was first coined by Wilson "Snowflake" Bentley (1865-1931). He admired the snowflakes and wrote: "Under the microscope, I found that snowflakes were miracles of beauty; and it seemed a shame that this beauty should not be seen and appreciated by others. Every crystal was a masterpiece of design and no one design was ever repeated...When a snowflake melted, that design was forever lost. Just that much beauty was gone, without leaving any record behind.”You can explore more about his life here. The physics of how snowflakes form is very complex and some researchers devote their entire life studying these. One of them is the physicist Ken Libbrecht.
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. The modern periodic table is based closely on the ideas he used: Molecular Workbench Three Views of MW Senior Scientist and Molecular Workbench Developer Charles Xie, Researcher and Manager Amy Pallant, and Technology and Curriculum Developer Dan Damelin describe the history of Molecular Workbench and our vision for the future.

The new Pivot Interactives website offers a powerful platform for students to learn science concepts and science process skills. It contains classroom-ready activities with integrated data tables and graphing capabilities, teacher-modifiable student instructions, and allows teachers to create classes to assign and grade student work. In addition, the platform features more video arrays with the Pivot Player interactive tools, and a user-interface that allows users to change variables within the videos, such as the mass of objects or frequency of a wave. Here are the changes underway: During late summer and fall 2017, many of the videos on the Direct Measurement Video website will be migrated to the Pivot Interactives site and will no longer be freely available.
STEM Resources for Teachers Connecting with the millennial generation, our current K-12 students, means a new way to teach and introduce material. Tech savvy Millennials love learning that is individually adapted to them with just enough detail that is needed at that particular moment in time. While very motivated and goal-oriented, Millennials want to learn in a team-oriented environment. Teaching to these students should use methods that connects to their needs while also meeting set educational standards. Looking for new ways to teach STEM? These free resources are available for you to infuse new ideas into your current curriculum. 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. In total, the graphic shows 44 elements whose supply is at risk.
Periodic Table Battleship I have posted a lot about Chemistry lately. My oldest has been studying it and really enjoying it. I love his science-y mind! Today I have a really fun & simple chemistry game to share. We played Periodic Table Battleship! This game can be played even by kids who know nothing about the Periodic Table Yet.
