Air resistance SC.6.P.13.2: Explore the law of gravity by recognizing that every object exerts gravitational force on every other object and that the force depends on how much mass the objects have and how far apart they are. Cognitive Complexity: Low SC.6.P.13.3: Investigate and describe that an unbalanced force acting on an object changes its speed, or direction of motion, or both. Cognitive Complexity: Moderate SC.6.N.1.1 Define a problem from the sixth grade curriculum, use appropriate reference materials to support scientific understanding, plan and carry 1 Jefferson County Science Scope and Sequence out scientific investigation of various types, such as systematic observations or experiments, identify variables, collect and organize data, interpret data in charts, tables, and graphics, analyze information, make predictions, and defend conclusions. Cognitive Complexity: High SC.6.N.1.2 Explain why scientific investigations should be replicable. Cognitive Complexity: High SC.6.N.1.3 Explain the difference between an experiment and other types of scientific investigation, and explain the relative benefits and limitations of each. Cognitive Complexity: High SC.6.N.1.4 Discuss, compare, and negotiate methods used, results obtained, and explanations among groups of students conducting the same investigation. Cognitive Complexity: High SC.6.N.2.3 Recognize that scientists who make contributions to scientific knowledge come from all kinds of backgrounds and possess varied talents, interests, and goals. Cognitive Complexity: Low Identify gravity as the force that causes objects to fall to Earth. (II, III) Design an experiment that demonstrates the different properties of gravity. (III) Describe unbalance forces using a graphic organizer. (IV) Objectives below are from Quarter 1A and should be embedded in this topic of study. Explain the difference between an experiment and other types of scientific investigations. Use appropriate reference materials to support scientific investigations of various types, such as systematic observation or experiments. Develop a hypothesis with one testable independent variable. Distinguish between dependent and independent variables and controls in a variety of activities. Explain why scientific investigations should be replicable. Conduct, discuss, and compare similar investigations by working cooperatively in groups. Collect and organize data in charts, tables, and graphics. Give examples of how advances in technology have affected scientific theories and laws. Compare and contrast the terms that describe examples of scientific knowledge such as: theory, law, hypothesis, and model. Distinguish between laws and theories by understanding that laws describe the what and theories explain the why. Explain why models are used in science to observe processes that happen too slowly, too quickly, or are too small or vast for direct observation. 2 Jefferson County Science Scope and Sequence SC.6.N.3.1 Recognize and explain that a scientific theory is a wellsupported and widely accepted explanation of nature and is not simply a claim posed by an individual. Thus, the use of the term theory in science is very different than how it is used in everyday life. Cognitive Complexity: Moderate Give examples of visual/physical, mathematical, and conceptual models as used in science. SC.6.N.3.2 Recognize and explain that a scientific law is a description of a specific relationship under given conditions in the natural world. Thus, scientific laws are different from societal laws. Cognitive Complexity: Moderate SC.6.N.3.4 Identify the role of models in the context of the sixth grade science benchmarks. Cognitive Complexity: Moderate LA.6.2.2.3 The student will organize information to show understanding (e.g., representing main ideas within text through charting, mapping, paraphrasing, summarizing, or comparing/contrasting); LA.6.4.2.2 The student will record information (e.g., observations, notes, lists, charts, legends) related to a topic, including visual aids to organize and record information and include a list of sources used; 3 Jefferson County Science Scope and Sequence MA.6.A.3.6 Construct and analyze tables, graphs, and equations to describe linear functions and other simple relations using both common language and algebraic notation. High MA.6.A.3.6 Construct and analyze tables, graphs and equations to describe linear functions and other simple relations using both common language and algebraic notation. Cognitive Complexity: High LACC.68.WHST.3.9: Draw evidence from informational texts to support analysis reflection, and research. MACC.6.SP.1.3: Recognize that a measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how its values vary with a single number. MACC.6.SP.2.5: Summarize numerical data sets in relation to their context, such as by: a. Reporting the number of observations. b. Describing the nature of the attribute under investigation, 4 Jefferson County Science Scope and Sequence including how it was measured and its units of measurement. c. Giving quantitative measures of center (median and/or mean) and variability (interquartile range and/or mean absolute deviation), as well as describing any overall pattern and any striking deviations from the overall pattern with reference to the context in which the data were gathered. d. Relating the choice of measures of center and variability to the shape of the data distribution and the context in which the data were gathered. LACC.68.RST.1.3: Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks. LACC.68.RST.2.4: Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 6–8 texts and topics. LACC.68.RST.3.7: Integrate quantitative or technical information expressed in words in a text with a version of that information expressed visually 5 Jefferson County Science Scope and Sequence (e.g., in a flowchart, diagram, model, graph, or table). LACC.68.RST.4.10: By the end of grade 8, read and comprehend science/technical texts in the grades 6–8 text complexity band independently and proficiently. LACC.68.WHST.1.2: Write informative/explanatory texts, including the narration of historical events, scientific procedures/ experiments, or technical processes. a. Introduce a topic clearly, previewing what is to follow; organize ideas, concepts, and information into broader categories as appropriate to achieving purpose; include formatting (e.g., headings), graphics (e.g., charts, tables), and multimedia when useful to aiding comprehension. b. Develop the topic with relevant, well-chosen facts, definitions, concrete details, quotations, or other information and examples. c. Use appropriate and varied transitions to create cohesion and clarify the relationships among ideas and concepts. d. Use precise language and domain-specific vocabulary to 6 Jefferson County Science Scope and Sequence inform about or explain the topic. e. Establish and maintain a formal style and objective tone. f. Provide a concluding statement or section that follows from and supports the information or explanation presented. 7
