UV-Visible Spectrophotometric Inquiry-Based Learning via STEM CAMP: Imitation of Syrup Drinks

Abstract

STEM (Science Technology Engineering Mathematics) activity is one of the approaches to science learning. It promotes students' 21st-century skills which lead to the development of innovation in the country. STEM activity together with inquiry-based learning (IBL) creates an effective learning experience. In the IBL-STEM activity, the laboratory instruments were used to enhance students' understanding in using a spectrophotometer and the concepts of the wavelength of light in nature, the concentration of the solution, and the quantification of the ppm (parts per million). It was found that IBL-STEM activity promoted critical thinking, problem-solving, and collaboration skills in students. Moreover, students had a better understanding of handling laboratory instruments, making the standard calibration curve, and interpreting data. This STEM activity broadened students' perspectives of the deployment of science and innovation. Also, it prepared students as life-long learners.
