Water - ice transition Methods The multi-frame model was prepared by Angel Herráez from molecular dynamics data kindly provided by Luboš Vrbka (Institute of Organic Chemistry and Biochemistry, Prague). Dr. 5 Mind-Blowing Ways Your Senses Lie to You Every Day #2. Your Brain Changes the Size of Objects Around You Yuliya Chsherbakova/Photos.com Your eyes are lying to you right now about something as basic as the size of the stuff you're looking at. MOLO - Database The Molecular Logic Database is designed to provide teachers and students with easy access to our model-based activities. The activities are derived largely, but not entirely, from projects of the Concord Consortium sponsored by the National Science Foundation (NSF). The models are primarily of interactions of atoms and molecules, or rule-based genetics. The model-based activities are presented in a variety of sizes, styles, and degrees of teacher support, but a subset of Stepping Stones (See Overview of Stepping Stones) has been built to provide entries to larger domains. All activities are accompanied by:
CORE_Index (home page) provides access to animations, demonstration videos, lab videos and lab documents taken from an online AP Chemistry course developed by NCSSM chemistry instructors Dr. Myra Halpin and Chuck Roser. CORE provides all the supporting resource materials from this course, but without the course instruction documents themselves. These materials are available to NCSSM students and instructors, and may be used by the general educational community worldwide for classroom support.

Chemistry Review Summary A water molecule has no overall or “net” charge. It is neutral. Because of the way oxygen and hydrogen are bonded together, water has an area of positive charge and an area of negative charge. Thriving Garden in Sealed Bottle Hasn't Been Watered in Over 40 Years When David Latimer planted a seed in a glass bottle on Easter Sunday of 1960 out of pure curiosity, he had no idea that it would flourish into a mass of greenery that would thrive untouched for several decades. Now, over half a century later, the sealed bottle garden is still growing as vigorously as ever, filling the bottle entirely with lush plant life, despite the fact that the last time Latimer watered it was in 1972. After initially pouring some compost into the globular bottle, Latimer used a wire to carefully lower in a spiderworts seeding, and then added a pint of water to the mix.
chemsoc timeline - flash We would like to invite you to suggest other items for inclusion in the chemsoc timeline. All genuine suggestions will be considered and those accepted will be credited to the individual responsible! The events do not have to be chemistry related - just notable discoveries or incidences that are of interest to scientists and the general public. Please Email firstname.lastname@example.org with your suggestion, where possible please include the date the event/discovery took place and some basic details: where it took place, who was involved and maybe some other sources of information. What is it? « Algodoo Algodoo is a unique 2D-simulation software from Algoryx Simulation AB. Algodoo is designed in a playful, cartoony manner, making it a perfect tool for creating interactive scenes. Explore physics, build amazing inventions, design cool games or experiment with Algodoo in your science classes.
Workbench - Database Molecular Workbench offers interactive, visual simulations and activities that have been widely used in science teaching for students of all ages. Our database is designed to provide teachers and students with easy access to our model-based activities. The activities are derived largely, but not entirely, from projects of the Concord Consortium sponsored by the National Science Foundation (NSF). The models are primarily of interactions of atoms and molecules, or rule-based genetics. All activities are accompanied by: colored icons to indicate degree of support technological requirements links to concepts and disciplines links to standards links to some textbooks
