Materials list Contains few of the materials actually used and/or is missing most of the reasons for inclusion. Contains all materials used but no reasons for inclusion, or contains most material used with reasons for inclusion. Contains all materials used and reasonable arguments for their inclusion. List is complete, concise and relevant.
Derivation and use of parabolic function Parabolic function is listed, calculations are unclear and derivation is sketchy. Little detail on how the function was used to construct the cooker is provided. Parabolic function is listed with calculations that attempt to justify its derivation. Calculations contain some errors or assumptions that affect the performance of the cooker. Vague details on how the function was used to construct the cooker. Contains a correct working parabolic function with explanation of how it was used in the construction of the parabola. Calculations are correct and relevant to the construction of the cooker.
Placement of focus of parabola Limited calculation of focus. Contains little justification for placement of hotdog in cooker.  Calculation of focus is apparent in written work and makes sense. Justification of placement of hotdog within cooker correlates to the calculation of focus from the parabolic function established earlier in the project. 
Light intensity at focus of parabola. The focus is difficult to find on the cooker. Light does not appear to come together in a single point on the side of the cooker. Focus can be seen on the cooker, light does form a point on the side of the cooker. Focus is bright and easily seen on the side of the cooker.
Solar Cooker Research Minimal or no research to is demonstrated to prove that solar cookers are being researched extensively. Some research has been done.  There is evidence of global research but evidence is minimal and less than 4 web addresses are listed to support there findings. Research on why solar cookers are being funded and researched extensively across the globe is clear and supported by evidence of web at least 4 page addresses.
Reflection At least 1 improvement to the design is clearly articulated in the write-up of the report. At least 2 improvements to the design are clearly articulated in the write-up of the report. At least 3 improvements to the design are clearly articulated in the write-up portion of the report.
