iRubric: DNA Model rubric

Does not contain one of the major component parts: Deoxyribose, Phosphate group or the 4 bases.

OR

Does not contain a key.

Contains at least Deoxyribose, phosphate & some bases.

There is a Key that explains the different component parts

OR

Has all of the major parts, including hydgrogen bonds but NO key.

Contains Deoxyribose, Phosphate Groups, 4 Bases (A-T, C-G) and Hydrogen Bonds.

All structures are clearly defined and recognized in a key.

Poor material choice

AND

no real relationship between size of component parts.

AND

Size is unrealistic

Materials are not adequate to show understanding for the relationship in size of the component parts

OR

Relationship between component parts is hard to understand.

OR



Project is too large or too small.

Use materials that were "found", shows understanding for the relationship in size of the component parts & is within the size requirements.
