Developing lesson plan of the biogas from animal’s dung STEM education

Abstract

The paper will clarify STEM education learning activity of designing biogas from animal’s dung. This activity was developed based on Sutaphan and Yuenyong [13] the context-based STEM education learning approach. The activity will start from identification of social issue of biogas that comes from animal dung and how to design biogas from animal’s dung. The possible solution will be introduced to the students to enhance them to develop the prototypes. Then, the lesson plan will provide activities regarding on the 7 stages of Sutaphan and Yuenyong [13] the context-based STEM education in order to scaffold students to practice knowledge for designing prototypes or products through engineer design process. The lesson plan will provide students to develop and use their integration of knowledge through biogas producing activity. For examples, physics (density of gases that lighter than air), biology (type of animal’s dung that fit and efficient for biogas), chemistry (composition of gas and dung), technology (design a tank that collect biogas from animal’s dung), engineering (how to make a gas separated by animal’s dung and flow it to the kitchen), mathematics (calculate the range of tank, pipe, and location to place the dung), financial issue (how to make an efficient biogas with a cheap cost). This paper may have implications for designing STEM education learning activities and adding value of local raw materials by using STEM education.
