In this lesson, young scientists are introduced to the concept of a phenomenon—an observable event in the natural world that prompts curiosity. Through engaging activities, such as observing a siphon experiment, students learn to make qualitative observations using descriptive words and quantitative observations with measurements. The lesson emphasizes the importance of both types of observations in understanding scientific events. Students are encouraged to think critically, document their observations, and differentiate between evidence-based facts and inferences. Ultimately, the goal is to foster investigative skills and a deeper understanding of scientific inquiry.
