Chemistry curriculum reform shows an explicit shift from traditional approach to scientific inquiry. This study aims to develop a guided inquiry-based laboratory worksheet on topic of heat of combustion. Implementation of this topic in high school laboratory is new because previously some teachers only focused the experiment on determining the heat of neutralization. The method used in this study was development research consisted of three stages: define, design, and develop. In the define stage, curriculum analysis and material analysis were performed. In the design stage, laboratory optimization and product preparation were conducted. In the development stage, the product was evaluated by the experts and tested to a total of 20 eleventh-grade students. The instruments used in this study were assessment sheet and students' response questionnaire. The assessment results showed that the guided inquiry-based laboratory worksheet has very good quality based on the aspects of content, linguistic, and graphics. The students reacted positively to the use of this guided inquiry-based worksheet as demonstrated by the results from questionnaire. The implications of this study is the laboratory activity should be directed to development of scientific inquiry skills in order to enhance students' competences as well as the quality of science education. © Published under licence by IOP Publishing Ltd.
