Core Skills Analysis
Science
Ella completed an experiment that illustrated the Law of Conservation of Mass, exploring the idea that matter is conserved during a change. The activity connected a scientific principle to direct observation, helping Ella consider how mass behaves when materials undergo a process. Ella practiced using an experiment to investigate a claim and relate evidence to a scientific concept. This experience supported Ella’s understanding of matter and how scientists use observations to explain what happens during changes.
Tips
Tips Build on Ella’s experiment by inviting Ella to explain the conservation principle in their own words, then draw a before-and-after model showing how matter can change form while being conserved. Try a teacher- or caregiver-supervised demonstration with a safe, sealed system and compare mass measurements before and after; discuss why keeping the system closed matters. Ella could also research an everyday change, such as melting ice, and predict what happens to the matter before checking the prediction through observation.
