Abstract
Abstract: This study aims to determine the ability of students in predicting a phenomenon based on facts found in everyday life, learning video observation, and explaining the findings from the video observations. This research used a descriptive methode. The research sample consists of 101 11th graders majoring in natural science from 3 different class group in one public high school in Bandung. The learning prosess was carried out online using G-Form Student Worksheet. The research consists of three stages: First, students predict phenomena in the combustion prosess of wood, paper, and LPG- Second, student sobserve the video of carbon compounds combustion- and Third, students explain the findings of their observations. The data obtained were than analyzed qualitatively. We found that 87% of students were able to predict the phenomena during the combustion process of wood, paper, and LPG and only 47% of students could mention that the remaining charcoal is composed of carbon. At the observation stage, 69% of students could observe the formation of CO2 and H2O compounds as a result of carbon compounds combustion. However, during the explanation step, only 4% of students can mention the elements C and H as the main elements that make up carbon compounds and only 21% of students can conclude that not all compounds containing elements C and H are carbon compounds.
