Middle school students introducing

Barke, Doerfler and Knoop [18] planned lectures according to the second hypothesis in middle school classes 14-16 years old students were supposed to understand acids, bases and neutralization. Instead of taking the usual equation HC1 + NaOH —> NaCl + H20 for the reaction, H + (aq) ions for acidic solutions and OII (aq) ions for basic solutions were introduced, the ionic equation of the formation of water molecules was explained H + (aq) ions + OH (aq) ions > H20 molecules . Later it was related that, with regard to neutralization, other students think of a formation of salt because NaCl is a product of this neutralization . Students discussed this idea with the result that no solid salt is formed by neutralization, Na + (aq) ions and Cl (aq) ions do not react but only remain by the neutralization. These ions are therefore often called spectator ions . 

Students at the middle school level should be encouraged to introduce positive behavior in the cyber world by creating and publishing their own writing, music, videos, and artwork. They also should understand issues related to copyright and public domain cyber resources. This includes knowledge of cyber resources and how they can be used. The ability to access and use data is a life skill they must process. Subject matter may involve activities from citation of a newspaper article for school research to distribution of copyrighted music via peer networks. Students need to know what is acceptable behavior and what is not (Conradson and Herntodez-Ramos, 2004).
