Materials

1. Conventional - any materials and adhesive can be used
2. Sustainable - The materials had to be durable, the adhesive had to be removable, and no one material could compromise the integrity or reusability of another
3. Sustainable - had to use materials that can be connected with no glue ( ex: we used cork to skewers into it in order to attach fins)

Time

• Conventional - accomplished the goal in 3 classes - WHM - did not compare time to build for each (was it different?)
• Sustainable - accomplished the goal in 6 classes - WHM - what were the goals; did you exceed any of the goals - like hit the green door?
• Sustainable - The sustainable designs required more time and effort to brainstorm and build. For instance, it was easier to solder the connections to the motor than it was to carefully wrap them. Glue was also easier than fixing and taping the joints. - WHM - did not quantify the differential design time and building time

Tools and techniques

1. Conventional - no limitations - WHM - make the comparison to sustainable - I am assessing evidence-based arguments, and you are not providing evidence
2. Sustainable - could not use glue, could not use solder. Heat - WHM - images of failed attempts would be helpful; else you are opining and you should state that it is your opinion
3. Sustainable - looked for easily reversible joining techniques, like puzzle joints or tape - WHM - images
