This learning resource focuses on identifying cause-and-effect relationships through a laboratory investigation of bean plants. Students will observe how varying amounts of water (50 ml, 100 ml, and 150 ml) influence plant growth. The activity involves matching specific causes (the amount of water given) to their respective effects (the height of the plants). Additionally, students will formulate predictions on how increased watering will impact growth and are encouraged to think critically about the reasons behind their predictions. This exercise not only enhances understanding of scientific inquiry but also fosters observation and reasoning skills in a practical context.
