This student is carrying his science project to school. Display projects involve a creative assembly of a display board and construction of a model to show a visual representation of a larger fact. Making a model of the Solar System, a house, or of a simple electric circuit are considered display projects. Display boards are used to enhance the ...

Some Wikipedians have formed a project to provide information related to chemistry. The main efforts focus on providing articles clearly written articles that give an overview of the topic, all supported by reliable sources. The Chemistry portal is maintained at Portal:Chemistry and the project banner is {{WikiProject Chemistry}}.
(The Greek word "lysis" (λύσις) means "loosing" or "setting free".) [citation needed] Important examples of electrolysis are the decomposition of water into hydrogen and oxygen, and of bauxite into aluminium and other chemicals. Electroplating (e.g. of Copper, Silver, Nickel or Chromium) is done using an electrolytic cell.
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
In solution chemistry and biochemistry, the Gibbs free energy decrease (∂G/∂ξ, in molar units, denoted cryptically by ΔG) is commonly used as a surrogate for (−T times) the global entropy produced by spontaneous chemical reactions in situations where no work is being done; or at least no "useful" work; i.e., other than perhaps ± P dV.
RSHS joined an international competition for Investigatory Projects. Alvin Jay Mostoles, then a third year student, represented the Philippines for its invention "Stone Segregator", in SEAMEO Science Fair, held in RECSAM Penang Malaysia. 2000 RSHS-I joined the National Secondary Achievement Test (NSAT).
[11] Discussion of banning phosphates from detergents in the United States started because of pollution of the Great Lakes. [12] Seventeen US states have partial or full bans on the use of phosphates in dish detergent, [13] and two US states (Maryland and New York) ban phosphates in commercial dishwashing. In 1983 there was a corruption scandal ...
