Support an argument that the gravitational force exerted by Earth on objects is directed down. Engaging in Argument from Evidence Engaging in argument from evidence in 3 5 builds on K 2 experiences and progresses to critiquing the scientific explanations or solutions proposed by peers by citing relevant evidence about the natural and designed world(s). Support an argument with evidence, data, or a model. PS2.B: Types of Interactions The gravitational force of Earth acting on an object near Earth s surface pulls that object toward the planet s center. Cause and Effect Cause and effect relationships are routinely identified and used to explain change.

(5-PS2-1) 3-5-ETS1-1 Engineering Design 3-5-ETS1- Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost. 1. The performance expectation above was developed using the following elements from the NRC document A Framework for K- 12 Science Education: Asking Questions and Defining Problems Asking questions and defining problems in 3 5 builds on grades K 2 experiences and progresses to specifying qualitative relationships. Define a simple design problem that can be solved through the development of an object, tool, process, or system and includes several criteria for success and constraints on materials, time, or cost. ETS1.A: Defining and Delimiting Engineering Problems Possible solutions to a problem are limited by available materials and resources (constraints). The success of a designed solution is determined by considering the desired features of a solution (criteria). Different proposals for solutions can be compared on the basis of how well each one meets the specified criteria for success or how well each takes the constraints into account.

FORCES, ENERGY AND MOTION GROUP SET 78790 3-5-ETS1-2 Engineering Design 3-5-ETS1- Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem. 2. The performance expectation above was developed using the following elements from the NRC document A Framework for K- 12 Science Education: Constructing Explanations and Designing Solutions Constructing explanations and designing solutions in 3 5 builds on K 2 experiences and progresses to the use of evidence in constructing explanations that specify variables that describe and predict phenomena and in designing multiple solutions to design problems. Generate and compare multiple solutions to a problem based on how well they meet the criteria and constraints of the design problem. ETS1.B: Developing Possible Solutions Research on a problem should be carried out before beginning to design a solution. Testing a solution involves investigating how well it performs under a range of likely conditions. At whatever stage, communicating with peers about proposed solutions is an important part of the design process, and shared ideas can lead to improved designs. Influence of Science, Engineering, and Technology on Society and the Natural World Engineers improve existing technologies or develop new ones to increase their benefits, decrease known risks, and meet societal demands.

MS-PS2-2 Motion and Stability: Forces and Interactions MS-PS2- Plan an investigation to provide evidence that the change in an object s motion depends on the sum of the forces on the object and the mass of the object. 2. [Clarification Statement: Emphasis is on balanced (Newton s First Law) and unbalanced forces in a system, qualitative comparisons of forces, mass and changes in motion (Newton s Second Law), frame of reference, and specification of units. Planning and Carrying Out Investigations Planning and carrying out investigations to answer questions or test solutions to problems in 6 8 builds on K 5 experiences and progresses to include investigations that use multiple variables and provide evidence to support explanations or design solutions. Plan an investigation individually and collaboratively, and in the design: identify independent and dependent variables and controls, what tools are needed to do the gathering, how measurements will be recorded, and how many data are needed to support a claim. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Connections to Nature of Science Scientific Knowledge is Based on Empirical Evidence Science knowledge is based upon logical and conceptual connections between evidence and explanations. PS2.A: Forces and Motion The motion of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change. The greater the mass of the object, the greater the force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion. All positions of objects and the directions of forces and motions must be described in an arbitrarily chosen reference frame and arbitrarily chosen units of size. In order to share information with other people, these choices must also be shared. Stability and Change Explanations of stability and change in natural or designed systems can be constructed by examining the changes over time and forces at different scales. RST.6-8.3 Follow precisely a multi-step procedure when carrying out experiments, taking measurements, or performing technical tasks. (MS-PS2-2) WHST.6- Conduct short research projects to answer a question (including a self-generated question), drawing on several sources and generating additional related, focused questions that allow for 8.7 multiple avenues of exploration.

MS-PS3-1 Energy MS-PS3- Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object. 1. Analyzing and Interpreting Data Analyzing data in 6 8 builds on K 5 and progresses to extending quantitative analysis to investigations, distinguishing between correlation and causation, and basic statistical techniques of data and error analysis. Construct and interpret graphical displays of data to identify linear and nonlinear relationships. PS3.A: Definitions of Energy Motion energy is properly called kinetic energy; it is proportional to the mass of the moving object and grows with the square of its speed. Scale, Proportion, and Quantity Proportional relationships (e.g. speed as the ratio of distance traveled to time taken) among different types of quantities provide information about the magnitude of properties and processes. RST.6-8.7 Integrate quantitative or technical information expressed in words in a text with a version of that information expressed visually (e.g., in a flowchart, diagram, model, graph, or table).

(MS-PS3-1) MS-PS3-2 Energy MS-PS3- Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the 2. system. [Clarification Statement: Emphasis is on relative amounts of potential energy, not on calculations of potential energy. Examples of objects within systems interacting at varying distances could include: the Earth and either a roller coaster cart at varying positions on a hill or objects at varying heights on shelves, changing the direction/orientation of a magnet, and a balloon with static electrical charge being brought closer to a classmate s hair. Examples of models could include representations, diagrams, pictures, and written descriptions of systems.] [Assessment Boundary: Assessment is limited to two objects and electric, magnetic, and gravitational interactions.] Developing and Using Models Modeling in 6 8 builds on K 5 and progresses to developing, using and revising models to describe, test, and predict more abstract phenomena and design systems. Develop a model to describe unobservable mechanisms. PS3.A: Definitions of Energy A system of objects may also contain stored (potential) energy, depending on their relative positions. PS3.C: Relationship Between Energy and Forces When two objects interact, each one exerts a force on the other that can cause energy to be transferred to or from the object. Systems and System Models Models can be used to represent systems and their interactions such as inputs, processes, and outputs and energy and matter flows within systems. SL.8.5 Integrate multimedia and visual displays into presentations to clarify information, strengthen claims and evidence, and add interest. (MS-PS3-2) 5 www.knexeducation.com

MS-PS3-5 Energy MS-PS3- Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object. 5. [Clarification Statement: Examples of empirical evidence used in arguments could include an inventory or other representation of the energy before and after the transfer in the form of temperature changes or motion of object.] Engaging in Argument from Evidence Engaging in argument from evidence in 6 8 builds on K 5 experiences and progresses to constructing a convincing argument that supports or refutes claims for either explanations or solutions about the natural and designed worlds. Construct, use, and present oral and written arguments supported by empirical evidence and scientific reasoning to support or refute an explanation or a model for a phenomenon. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Connections to Nature of Science Scientific Knowledge is Based on Empirical Evidence Science knowledge is based upon logical and conceptual connections between evidence and explanations. PS3.B: Conservation of Energy and Energy Transfer When the motion energy of an object changes, there is inevitably some other change in energy at the same time. Energy and Matter Energy may take different forms (e.g. energy in fields, thermal energy, energy of motion). WHST.6-8.1 Write arguments focused on discipline content. (MS-PS3-5) Reason abstractly and quantitatively. (MS-PS3-5) 6.RP.A.1 Understand the concept of ratio and use ratio language to describe a ratio relationship between two quantities.

Define a design problem that can be solved through the development of an object, tool, process or system and includes multiple criteria and constraints, including scientific knowledge that may limit possible solutions. ETS1.A: Defining and Delimiting Engineering Problems The more precisely a design task s criteria and constraints can be defined, the more likely it is that the designed solution will be successful. Specification of constraints includes consideration of scientific principles and other relevant knowledge that are likely to limit possible solutions. Influence of Science, Engineering, and Technology on Society and the Natural World All human activity draws on natural resources and has both short and long-term consequences, positive as well as negative, for the health of people and the natural environment. The uses of technologies and limitations on their use are driven by individual or societal needs, desires, and values; by the findings of scientific research; and by differences in such factors as climate, natural resources, and economic conditions. RST.6-8.1 WHST.6-8.8 Reason abstractly and quantitatively.

Analyze and interpret data to determine similarities and differences in findings. ETS1.B: Developing Possible Solutions There are systematic processes for evaluating solutions with respect to how well they meet the criteria and constraints of a problem. Sometimes parts of different solutions can be combined to create a solution that is better than any of its predecessors. ETS1.C: Optimizing the Design Solution Although one design may not perform the best across all tests, identifying the characteristics of the design that performed the best in each test can provide useful information for the redesign process that is, some of those characteristics may be incorporated into the new design.
