In Science class, P5 students explored changes in states of matter, focusing on evaporation and condensation. To deepen their understanding of condensation, they conducted an experiment to investigate the factors that affect the rate of condensation of water vapor in the air.
The lesson began with a review of the condensation process. After recalling prior knowledge, students were divided into groups and tasked with identifying the experimental method and the tools needed. The teacher then reviewed the procedure with the class, emphasizing the importance of following each step carefully to ensure accurate results. This preparation helped students work together effectively to conduct the experiment smoothly.
For the experiment, each group poured 100 ml of water into two glasses, labeled A and B. Glass A was filled with 3 ice cubes, while Glass B contained 6 ice cubes. Students then observed the condensation on the surfaces of each glass, noting any differences. Through this observation, they discovered that the temperature of each glass (influenced by the number of ice cubes) impacted the rate of condensation.
Following the experiment, students recorded their findings by answering questions about the condensation process and identifying the variables involved. This hands-on activity not only strengthened their understanding of condensation but also connected scientific concepts to their everyday experiences. ***
