Stem design an efficient house Students use STEM and engineering skills and knowledge to design and build a house. Rubric Code: YX84662 By Frogen Draft Public Rubric Subject: Science Type: Assessment Grade Levels: 6-8

Energy Efficient House
	fair 2 pts	Fair 5 pts	Good 7 pts	Excelent 10 pts
Scienfitic knowedge in the design	fair Hardly any Scientific justification is made.	Fair Little to no Scientific explanation	Good students partially explain their selection and arrangement of materials based on knowledge of heat transfer.	Excelent Students toughly articulate their selection and arrangement of materials based on their scientific knowledge about heat transfer
Engeneering design principles	fair No engineering justification is made.	Fair very little engineering principles used to talk about house design.	Good students mostly refer to engineering principals.	Excelent Students adequately refer to engineering principals.
Geometrc principales in the design	fair No size limitations ( constraints) were met	Fair A little thought was given to geometric design to determine the design of the house.	Good Student mostly draw on geometric knowledge in determining the structure and shape of the house	Excelent Students thoroughly draw on geometric knowledge determining the structure and shape of the house.
Size of the house	fair No size requirements were met.	Fair one of the size requirement dimensions were met.	Good two or of the size requirements were met	Excelent all of the size requirements are met.
Cost of materials	fair The insulation of the house costs more than 17$. Costs > 17$.	Fair Insulation costs are 15 - 17 $	Good The groups insulation design costs more than 12$ but still less than 17$	Excelent The groups insulation design costs <10$
Performance of prototype (end temp)	fair The group only improved their heating efficiency of their house by 10 % or less	Fair The Thermal efficiency of the house is between 10% and 15%	Good The thermal efficiency of the house improved 15% -20 %	Excelent the thermal efficiency of the house greatly improved more than 20%
Creativity	fair Nothing was done to improve the look of your house.	Fair One or so creative touches added to the house. May be started but incomplete in several spots.	Good Some aesthetic appeal was added to the design of the house and mostly completed.	Excelent The house has multiple creative improvements to the exterior of the house and completed.
