For each framework, it lists the types of skills and knowledge students should demonstrate at different levels (Level 1 and Level 2) across various contexts and practical situations. The frameworks focus on skills like thinking scientifically, understanding applications of science, communicating collaborating, using investigative approaches, and working critically with evidence.
