This resource is explicitly designed to build towards this performance expectation.
Comments about Including the Performance Expectation
This activity seems to have been written prior to the release of the NGSS so it does not refer explicitly to this Performance Expectation, but students are engaged in making sense of the relationship between structure and function as they test the effectiveness of three fish mouth types with three types of food sources. Photos are provided to engage students in the consideration of mouth structures, but more effective pictures for this purpose and additional background information can be found at: https://www.floridamuseum.ufl.edu/fish/discover/fish/anatomy/mouth-types/
