Abstract
Spectroscopy is part of modern chemistry, which allows chemists to study the structure and properties of atoms and molecules. Unfortunately, many pre-service chemistry teachers are not usually introduced to the basic principles behind this technique. The study aims to develop simple and low-cost spectrophotometers. Project-based learning was used in this study. The experiments fit well into an analytical chemistry course and take a standard (1 h) lab period. Low-cost spectrophotometers made by pre-service chemistry teacher have a fairly good sensitivity compared to modern spectrophotometers. Pre-service chemistry teachers have better knowledge about the spectroscopy, and the basic principles of the instrument after developing Low-cost spectrophotometers. In addition, the project activities also enhance the creative thinking skills of the pre-service chemistry teacher
