ACID AND BASES : GRADE-7




Grade 7 is learning about acid and bases. After the introductory session the students were asked to bring things at home which contain either acid or base. In the next session, they enthusiastically displayed the items they brought. Things brought by them were vinegar, oxalic acid, harpic, pepsi, apple, grapes, sweet lime, lemon, boric powder, citric acid powder etc.
