Middle School Chemistry | Download Free Science Activities, Access Chemistry Multimedia, Find Information on Workshops 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. This video explains and illustrates the molecular structure of sodium chloride (NaCl) crystals; the structure and symmetry of crystal lattices; and why one crystalline solid, salt, melts another, ice.
Chemistry game online,free science games for kids to play on PC,fun interactive activity for middle,high school students Chemikul is an online science/ chemistry-based game that will send you on an atomic mind-bender of confusion – as well as provide endless hours of enjoyment! With super-slick ambient graphics and simple acoustics, it’s a learning experience that anyone can enjoy. The goal is to create molecules using all of the atoms floating in the game screen. Win the game by using up the Valence of each atom. How To Play: Use your computer mouse to make connections between the atoms by holding down the left mouse button and then joining to the other atoms.
Babies See Pure Color, but Adults Peer Through Prism of Language When infant eyes absorb a world of virgin visions, colors are processed purely, in a pre-linguistic parts of the brain. As adults, colors are processed in the brain’s language centers, refracted by the concepts we have for them. How does that switch take place? And does it affect our subjective experience of color? Such tantalizing questions, their answers still unknown, are raised by this developmental shift in color categorization, described today in the Proceedings of the National Academy of Sciences. To test the phenomenon, a team of British and English researchers asked adults and infants to focus on a briefly flashing target circle. Sometimes the target appeared in the subjects’ right visual fields – roughly speaking, the right half of a person’s field of vision, which is transmitted from the eyes to the brain’s left hemisphere, where language processing also takes place. Does this mean that adults and infants see the same colors differently? But might adults see colors differently?

Quantitative chemistry Quantitative chemistry is a very important branch of chemistry because it enables chemists to calculate known quantities of materials. For example, how much product can be made from a known starting material or how much of a given component is present in a sample. Quantitative analysis is any method used for determining the amount of a chemical in a sample. The amount is always expressed as a number with appropriate units. Understand the core ideas in quantitative chemistry Explain how the core ideas of quantitative chemistry develop and progress throughout secondary education Identify common misconceptions and know how these can be addressed Confidently and competently teach aspects of quantitative chemistry to secondary aged students Access a range of activities and resources to support students in their learning of quantitative chemistry
How Much Sleep Do You Really Need? Sleep is one of the richest topics in science today: why we need it, why it can be hard to get, and how that affects everything from our athletic performance to our income. Daniel Kripke, co-director of research at the Scripps Clinic Sleep Center in La Jolla, Calif., has looked at the most important question of all. In 2002, he compared death rates among more than 1 million American adults who, as part of a study on cancer prevention, reported their average nightly amount of sleep. Q: How much sleep is ideal? A: Studies show that people who sleep between 6.5 hr. and 7.5 hr. a night, as they report, live the longest. Morbidity [or sickness] is also "U-shaped" in the sense that both very short sleep and very long sleep are associated with many illnesses—with depression, with obesity—and therefore with heart disease—and so forth. I think we can speculate [about why people who sleep from 6.5 to 7.5 hr. live longer], but we have to admit that we don't really understand the reasons.
