Chemical experiments play an important role in the development process of human perception of the world, and it is the foundation of teaching chemistry. Experiments are bridges between theory and practice that help students improve their practice skills and their thinking, thus inspiring them to learn chemistry.

Eight principles and five methods can be applied to plan chemistry lessons with experiments. Chemistry practice lessons should be planned in the light of Spickler method to improve students' independence, creativity and scientific passion.
