Developing Puzzles Laboratory Safety Symbols for Laboratory Introduction

This work describes a study of puzzles development of laboratory safety symbols for laboratory introduction. The puzzles were purposed as a learning media for students prior to work in chemistry and science laboratory. The puzzles consisted of two different standard systems, Material Safety Data Sheet (MSDS) and National Fire Protection Association (NFPA) 704. For instructional development, the media was developed using four-D model (Define, Design, Develop, and Disseminate).
