Exemplars (from the NaCCA curriculum)
Project-based Learning: - In mixed-ability groups, do a mini-investigation on the processes of removal of waste by the human excretory system using technological devices. - In mixed-ability/ mixed-sex groups, perform an activity to demonstrate the process for the removal of waste from the human body system. Teaching and Learning Resources: - Models or videos (see the link below) (https://www.kenhub.com/en/library/anatomy/human-body- systems) - chart/picture, books - Books - Internet resources - Journals - Magazines Assessment (2.2.1.AS.2). The document marks these depth-of-knowledge levels for this indicator: Level 3 Strategic reasoning.
