Research On The Application Of Chemistry Interesting Experiment In Teaching Design

Interesting chemistry experiment is a catalyst for students to learn chemistry,which plays a very important role in chemistry teaching.Using this catalyst will greatly promote students' chemistry learning.The author,through his lectures,lectures,and his own learning experience during the teaching practice,combined with a large number of literature and the latest development of basic chemistry education,decided to combine chemistry teaching,chemistry interesting experiment,the new curriculum standard(chemistry)of the 2017 edition,to strike out a set of combination boxing,teaching design and research.Study.Based on the existing literature and materials,this paper verifies and refines these experiments in the laboratory,and carries out teaching design according to the latest curriculum standard(2017).The aim is to combine chemistry interesting experiment with chemistry teaching,so that students can improve their interest in learning,accept knowledge better,and develop their inquiry ability.In this process,they can feel the mysterious charm of chemistry.At the same time,they can take chemistry interesting experiment as a breakthrough point to let more people understand chemistry.Chemistry is more closely linked to human life.In the paper,the theoretical viewpoints are mainly discussed by specific chemical interesting experiments.It can be divided into three parts.The first part is to apply chemistry interesting experiment to chemistry teaching to improve students' interest in learning.This paper mainly demonstrates the color reaction experiment of Shenshui development,chemical cipher letter,invisible ink and calligraphy without words.Through these four interesting experiments on color reaction,students can feel the brilliance and colorfulness of chemistry,and thus enhance their interest in learning.The second part is to apply chemistry interesting experiment to chemistry teaching to help students memorize knowledge.It is mainly through the water "fried" eggs,"sprouts" after rain,Shenlai "pen" these four chemical interesting experiments about the nature of concentrated sulfuric acid to strengthen students' knowledge of concentrated sulfuric acid.The third part is to apply chemistry interesting experiment to chemistry teaching,so as to develop students' inquiry ability.Mainly through the order of metal activity to demonstrate this knowledge point,there is hydrogen on both sides of the metal replacement,such as iron replacement of copper sulfate in copper,aluminum replacement of copper sulfate in copper,hydrogen metal replacement,such as copper elemental replacement of silver nitrate in silver;hydrogen metal replacement,magnesium bars to replace iron chloride in silver Iron in the middle.Through the further exploration of the above three kinds of experiments,we finally come to the conclusion.
