Abstract
Microscopic expansion is the vibration and rotation of the constituent atomic movements caused by the input heat so that the heat of the object expands in all directions. The expansion process causes an increase in length with a very small order and is difficult to observe through real practice. Developing an integrated system in the form of a virtual laboratory that can assist lecturers and teachers in teaching expansion material through investigation is the goal of research. research design and research development (DDR) with the ADDIE model was chosen in this study. The results of the research resulted in the design of a thermal expansion virtual laboratory integration system. The results of the virtual laboratory thermal expansion system can show up to a microscopic scale change in the form of an increase in length from the expansion process. The design consists of providing tools and materials virtually, practicum design, and data collection, and visualization of thermal expansion microscopically and graphically.
