Reaction of Ammonia gas

 

                                                                  On Wednesday I conducted the Thinktac first experiment for 5th class i.e. Reaction of ammonia gas. First I told about Think tac project. Later I revised the types of senses and told about uses and side effects of ammonia. Students are very curious to do the experiment. First they  smell the both the chemicals. After that they mixed the both the chemicals. They found  the temperature of container was cold and there was a pungent smell of the ammonia gas.  All students enjoyed the experiment.
