Scaffolding is one of the several aspects of effective instruction that can be applied in the context of language learning. Although teachers might be enthusiastic about the idea of scaffolding, it must be borne in mind that scaffolding is not simply synonymous with teacher support.

How does one prevent such a fire from happening​
valentina_108 [34]

Answer:

water

Explanation:

Water puts out fire by creating a barrier between the fuel source and the oxygen source (it also has a cooling effect which has to do with the energy required to convert liquid water into water vapor). It does this because it is a completely, 100% oxidized material. It simply cannot oxidize any further so it will not “burn”. This smothers the fire. The same thing would happen if you used the ashes that remained after a completely spent fire. Or, as I mentioned before, CO2.
