Water is an amazing substance! It can form into a beautiful snowflake in its solid state or evaporate into the air as a gas. Experiment with solids, liquids and gases to learn more about these states of matter. How do objects move? What lies beneath the surface of our Earth? The human body is made of various chemicals to help us smell, see, move, and most importantly, survive. Have some fun playing with science. Tag along with our friend Meg A.
ZME Science - science news, research, health, environment, spaceVirtual LabsThe 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. Please scroll below to find our collection of pre-written problems, they have been organized by concept and ranked by difficulty. Stoichiometry The Mole, Molarity, and Density Glucose Dilution Problem In this activity, students use the virtual lab to create a 0.025M glucose solution from a standard 1M glucose solution.
Chemical & Engineering News: What's That Stuff?You might ask yourself... What's That Stuff? Ever wondered about what's really in hair coloring, Silly Putty, Cheese Wiz, artificial snow, or self-tanners? Sort: Alphabetically (Text Only) | Most RecentHousehold Science for Kids: Slime & PolymersWhat's going on? When you mix Elmer's glue with a bit of water, you make a substance that is known as a polymer (polyvinyl acetate) and that the borax solution (sodium tetraborate) is a 'cross-linking' substance that binds the polymer chains together to make the glue solution thicker. So, as the polymer chains get more 'bound-together', it gets harder for them to move around, and your slime starts to be more like Silly-putty™. Experiment with adding more borax solution to see if this indeed makes the slime thicker or thinner. Knowing just how much Borax solution to add is the trick to this experiment. The substance known as 'Gak™' is really a specialized form of a polymer known as Poly-vinyl Alcohol, but is not too far off what we made with Elmer's glue.

Current Review Gravity Space movies, such as "Gravity," are almost always grandiose in their storytelling aspirations. Current Recommendation 'How To Survive A Plague' The history of science movies and the Oscars is not a very long one. Recent Recommendation 'Last Call At The Oasis' Watching the havoc caused by Hurricane Sandy and other recent water-related natural disasters, it's hard to imagine that global water shortages represent an environmental crisis on par with climate change.
