To support and popularize Science and Technology (ST) to the Macao students and to train their interest are important. Since there were less than 7% of the higher educational students majored in ST in 2013. Therefore, the author, who is a guide of a telecommunication gallery in Macao, also has the duty to increase students' interest in ST. For this purpose, some science workshops, courses and demonstrations are designed by the author which are based on the internet information. In this paper, a do it yourself (DIY) battery workshop, a DIY simple electronic piano course and an electromagnetic demonstration are introduced with the examples to show how these programs are designed to train the student visitors' interest in ST. With the designs, science concepts and knowledge from books are presented in practical ways with real life examples for stimulating the students' creativities and initiatives of doing science experiments.
