• Understand how theories are developed.
• Identify questions that can be answered through scientific investigations and evaluate the appropriateness of questions.
• Design and conduct a scientific investigation and understand that current scientific knowledge guides scientific investigations.
• Describe relationships using inference and prediction.
• Use appropriate tools and technologies to gather, analyze, and interpret data and understand that it enhances accuracy and allows scientists to analyze and quantify results of investigations.
• Develop descriptions, explanations, and models using evidence and understand that these emphasize evidence, have logically consistent arguments, and are based on scientific principles, models, and theories.
• Analyze alternative explanations and understanding that science advances through legitimate skepticism.
• Use mathematics in all aspects of scientific inquiry.
• Understand that scientific investigations may result in new ideas for study, new methods, or procedures for an investigation or new technologies to improve data collection.
