Progression of the Science and Engineering Practice of Planning and Carrying Out Investigations: 1. Asking Questions: Students learn to ask scientific questions that can be investigated through empirical evidence. They develop an understanding of the importance of asking clear and testable questions. 2. Planning Investigations: Students learn to plan investigations by identifying relevant variables, determining appropriate methods, and selecting appropriate tools and techniques. They develop skills in designing fair tests and controlling variables. 3. Conducting Investigations: Students learn to carry out investigations systematically, following the plans they have developed. They develop skills in collecting and recording data accurately and making observations. 4. Analyzing and Interpreting Data: Students learn to analyze and interpret data collected during investigations. They develop skills in organizing data, identifying patterns, and making evidence-based claims. 5. Using Mathematics and Computational Thinking: Students learn to use mathematical and computational thinking to analyze and interpret data. They develop skills in using mathematical models, making calculations, and using computer simulations. 6. Constructing Explanations: Students learn to construct explanations and develop models based on evidence from investigations. They develop skills in using evidence to support claims and reasoning scientifically. 7. Engaging in Argument from Evidence: Students learn to engage in argumentation based on evidence from investigations. They develop skills in defending their claims, critiquing the claims of others, and revising their explanations based on evidence. Performance Expectations that utilize the Science and Engineering Practice of Planning and Carrying Out Investigations: 1. MS-PS1-3: Gather and make sense of information to describe that synthetic materials come from natural resources and impact society. 2. HS-LS2-1: Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales. 3. HS-LS2-4: Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem. 4. MS-ESS2-1: Develop a model to describe the cycling of Earth's materials and the flow of energy that drives this process. 5. HS-PS1-2: Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties. These Performance Expectations provide specific examples of how the Science and Engineering Practice of Planning and Carrying Out Investigations can be applied across different grade levels and scientific concepts. They highlight the importance of students engaging in hands-on investigations to develop their scientific skills and understanding.
