This study has represented a model of experimental exercises in teaching chemistry. The model, which is the type of exercise associated with chemistry laboratories that when students answer them, they have to get the basic skills of practice chemistry. By analyzing the model of experimental exercises, we have proposed two underpinnings to design these exercises. On that basic, we proposed the way to design new experimental exercises. These methods are analyzed in detail and there are the attached application so that teacher can apply to design the same cases. Based on the proposed methods, we have designed sample exercises used in high school chemistry teaching. The exercises were solved clearly and evaluation of chemistry practical skills for students. This type of exercises is always attractive to create certain excitements for teachers and students in the teaching and learning chemistry in high school.
