(MS-LS1-1)Ĭonstructing Explanations and Designing SolutionsĬonstructing explanations and designing solutions in 6–8 builds on K–5 experiences and progresses to include constructing explanations and designing solutions supported by multiple sources of evidence consistent with scientific knowledge, principles, and theories. Conduct an investigation to produce data to serve as the basis for evidence that meet the goals of an investigation.Planning and carrying out investigations in 6-8 builds on K-5 experiences and progresses to include investigations that use multiple variables and provide evidence to support explanations or solutions.
Develop a model to describe unobservable mechanisms.Develop and use a model to describe phenomena.Modeling in 6–8 builds on K–5 experiences and progresses to developing, using, and revising models to describe, test, and predict more abstract phenomena and design systems. Science and Engineering Practices Developing and Using Models The performance expectations above were developed using the following elements from the NRC document A Framework for K-12 Science Education: Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories. ĭevelop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism. Ĭonstruct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms. Ĭonstruct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms.
Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants respectively. Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells. ĭevelop and use a model to describe the function of a cell as a whole and ways the parts of cells contribute to the function. Students who demonstrate understanding can: MS-LS1-1.Ĭonduct an investigation to provide evidence that living things are made of cells either one cell or many different numbers and types of cells.
