This document discusses key scientific concepts and the scientific process. It explains that the scientific process begins with asking questions and developing hypotheses, then conducting experiments to collect data and make observations. The results must be observable, measurable, and repeatable. Some common elements of the scientific process are identifying variables, measuring impacts, and determining cause and effect relationships. The document also discusses how scientists organize components into logical systems and hierarchies. It notes that understanding variation, change, and diversity in natural elements provides insights. Finally, it briefly touches on the field of materials science, which designs new materials through an interdisciplinary approach combining various fields of science and engineering.
