Children Science Links-Kids' Resources Science for Kids 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.
Household Science for Kids: Slime & Polymers What'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.
Cool Science Experiments for Kids: Water's Skin & Surface Tension | ExpertVillage Videos In this free instructional video clip series, our expert will demonstrate a popular children's science experiment called Water's Skin (surface tension). Water's surface tension is characterized by an elastic-type sheet on the edge of the liquid. In physics, this phenomenon is known as water's skin, as the thin layer of “skin” allows certain insects, small metal objects and other minuscule things to seemingly walk on water. It is easy to see why such a phenomenon would be interesting to kids, especially children with any sort of interest in science or biology.
