The performance expectations in fourth grade science help scholars formulate answers to questions such as: “What are waves and what are some things they can do? How can water, ice, wind and vegetation change the land? What patterns of Earth’s features can be determined with the use of maps? How do internal and external structures support the survival, growth, behavior, and reproduction of plants and animals? What is energy and how is it related to motion? How is energy transferred? How can energy be used to solve a problem?” In fourth grade performance expectations, scholars are expected to demonstrate grade-appropriate proficiency in asking questions, developing and using models, planning and carrying out investigations, analyzing and interpreting data, constructing explanations and designing solutions, engaging in argument from evidence and obtaining, evaluating, and communicating information. Scholars are expected to use these practices to demonstrate understanding of the core ideas. (“Science.” Oklahoma State Department of Education, 2020, sde.ok.gov.)
