               EXPERIMENT: - To understand the chemical change taking place on the reaction
               when exhaled air is passed through lime water.

















               Materials Required:


                Test-tube, cork, cork driller, lime water & straw.

               Observation: Students will observe the change in colour of lime water to milky by
               blowing exhaled air into it.

               Inference: Lime water reacts with the exhaled air which contains carbon dioxide, the
               colourless solution of lime water changes to white.
