The Development And Teaching Practice Of Interesting Chemistry Experiment In Primary School Science

In the textbooks of primary science,there are many chemistry knowledge related to real life.And chemistry is also a subject based on experiments.So these interesting experiments with 'magic' colors would be more attractive to students.In our teaching,how to design some interesting experiments skillfully,which follow ' phenomenon out of textbooks and principle in textbooks',can make students be easier to accept chemical knowledge,and also can stimulate their curiosity greatly.With full enthusiasm in their study,students will study chemical actively,which can achieve efforts twice with half done.Most of the principles of chemical experiments can not be explained clearly to the primary school students,for which are out of the depth of their understanding.Too much expanation will make them confused,and then lose their interest in chemical,so it's enough for pupils to get the simple knowledge and concepts related to life.In my class,I select the chemical red and green light experiment,the blue bottle experiment,the balloon experiment,the elephant toothpaset experiment and the egg's floating experiment.The main purpose of these interesting experiments is to stimulate the pupils' subjective initiative,to cultivate their hands-on ability,and to develop their spirit in creation and corperation.The teaching practice of interesting chemistry experiment has achieved good results.
