TR 1.3: Surprising Spider Silk
OBJECTIVE: KWBAT build and analyze physical models of spider silk strands of varying flexibility to investigate how the structure of proteins determines their function —how they connect to form more flexible or less flexible spider silk.

How do you think a spider could have different features for a trait?
True or false:
The kind of protein molecules a spider makes for a feature determines its trait for that feature.

True or False:
The weight of the spider silk is not a feature, it is a trait.
