NEXT GENERATION SCIENCE STANDARDS
PS2-2: Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of forces on the object and the mass of the object.
PS2-4: Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.
ETS1-1: Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
ETS1-2: Evaluate competing design solutions using a systematic process to determine how ETS1-3: Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success. ETS1-4: Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that a alternate design can be created. NGSS:
Constructing 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 ideas, principles, and theories. (Apply scientific ideas or principles to design an object, tool, process or system.)
