DE.1. Nature and Application of Science and Technology
1.1. Understandings and Abilities of Scientific Inquiry
Enduring Understanding: Scientific inquiry involves asking scientifically-oriented questions, collecting evidence, forming explanations, connecting explanations to scientific knowledge and theory, and communicating and justifying the explanation.
1.1.A. Understand that: Scientific investigations involve asking a focused scientific question. Investigations differ depending upon the question being asked.
1.1.A.1. Be able to: Generate focused questions and informed predictions about the natural world. (Level: Essential)
1.1.C. Understand that: The purpose of accurate data collection is to provide evidence to compare with the prediction.
1.1.C.1. Be able to: Accurately collect data using observations, simple tools and equipment. Display and organize data in tables, charts, diagrams, and bar graphs or plots over time. Compare and question results with and from others. (Level: Essential)
1.1.D. Understand that: The body of scientific knowledge grows as scientists ask questions, conduct investigations, develop explanations and compare results with what is already known.
1.1.D.1. Be able to: Construct a reasonable explanation by analyzing evidence from the data. Revise the explanation after comparing results with other sources or after further investigation. (Level: Essential)
1.1.F. Understand that: The use of mathematics, reading, writing, and technology are important in conducting scientific inquiries.
1.1.F.1. Be able to: Use mathematics, reading, writing, and technology when conducting scientific inquiries. (Level: Important)
DE.2. Materials and Their Properties
2.1. Properties and Structure of Materials
Enduring Understanding: The structures of materials determine their properties.
2.1.A. Observable physical properties can be used to classify materials. These physical properties may include solubility, mass, magnetism, and electrical conductivity. Tools such as graduated cylinders, balances, rulers, magnifiers, simple circuits, and magnets are used to study the physical properties. (Level: Essential)
