                                  [7.ETS.1.4] - Generate and analyze data from iterative testing and modification of a proposed object, tool, or process to optimize the object, tool, or process for its intended purpose.*
                            
                            
                           
                            
                            
                         
                     
                    
                
                [7.RP.A.2.a] - 
  Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin.
[7.PS.3.3] - 
  Apply scientific principles of energy and heat transfer to design, construct, and test a device to minimize or maximize thermal energy transfer.*
Clarification Statement: Examples of devices could include an insulated box, a solar cooker, and a vacuum flask. State Assessment Boundary: Accounting for specific heat or calculations of the total amount of thermal energy transferred is not expected in state assessment.
                [7.ETS.1.7] - 
  Construct a prototype of a solution to a given design problem.*
