  2. Dihydrogen monoxide parody - Wikipedia

    en.wikipedia.org/wiki/Dihydrogen_monoxide_parody

    Dihydrogen monoxide is a name for the water molecule, which comprises two hydrogen atoms and one oxygen atom (H 2 O).. The dihydrogen monoxide parody is a parody that involves referring to water by its unfamiliar chemical systematic name "dihydrogen monoxide" (DHMO, or the chemical formula H 2 O) and describing some properties of water in a particularly concerning manner — such as the ...

  3. The 30 most impressive science fair projects in the country - AOL

    www.aol.com/article/2015/10/13/the-30-most...

    Courtesy of Society for Science & the Public. At age 12, Audrey Glende has found a way to help save lives — fish lives. Glende realized that fish waste produces the toxic chemical ammonia that ...

  4. Salt metathesis reaction - Wikipedia

    en.wikipedia.org/wiki/Salt_metathesis_reaction

    The release of carbon dioxide gas from the reaction mixture drives the reaction to completion. For example, a common, science-fair "volcano" reaction involves the reaction of hydrochloric acid with sodium carbonate: 2 HCl + Na 2 CO 3 → H 2 CO 3 + 2 NaCl H 2 CO 3 → H 2 O + CO 2

  5. Non-Newtonian fluid - Wikipedia

    en.wikipedia.org/wiki/Non-Newtonian_fluid

    Another example of non-Newtonian fluid flow is chilled caramel ice cream topping (so long as it incorporates hydrocolloids such as carrageenan and gellan gum). The sudden application of force —by stabbing the surface with a finger, for example, or rapidly inverting the container holding it—causes the fluid to behave like a solid rather than ...

  6. Miscibility - Wikipedia

    en.wikipedia.org/wiki/Miscibility

    An example in liquids is the miscibility of water and ethanol as they mix in all proportions. [1] By contrast, substances are said to be immiscible if the mixture does not form a solution for certain proportions. For one example, oil is not soluble in water, so these two solvents are immiscible

  7. Granular convection - Wikipedia

    en.wikipedia.org/wiki/Granular_convection

    Once a homogeneous mixture of granular materials has been produced, it is usually undesirable for the different particle types to segregate. Several factors determine the severity of the Brazil nut effect, including the sizes and densities of the particles, the pressure of any gas between the particles, and the shape of the container.

  8. Science fair - Wikipedia

    en.wikipedia.org/wiki/Science_fair

    A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.

  9. Mixing (physics) - Wikipedia

    en.wikipedia.org/wiki/Mixing_(physics)

    Mixing in a ball of colored putty after consecutive iterations of the Smale horseshoe map (i.e. squashing and folding in two). In physics, there are several distinct notions of mixing, all of which try to capture the common-sense notion of mixing, but using rather disparate formal methods, techniques and definitions.
