Introducing scientific concepts to early years requires a different approach as compared to higher grades. Young children can better comprehend concepts with practical demonstrations. For giving children understanding of volcanoes, they were shown video clip and pictures of erupting volcanoes. To further help our students comprehend the phenomenon of volcanic eruptions the were shown a chemical reaction. The models of volcanoes were made by the teachers. They used vinegar, baking soda, food colour and dish soap to perform this experiment. This demonstration showed an acid base reaction, in which, the acid (vinegar) chemically reacted with base (the baking soda) and the two released carbon dioxide gas which bubbled out. The liquid soap helped in making the ‘lava’ foamy.
Students enjoyed watching the quick reaction and hence in a fun way learnt about volcanoes.
