For this task students are asked two questions about early Polynesian navigation. Students need to identify features of the environment that explorers would have used to navigate home and to find new land.
Plan an investigation to find out which of two students' predictions is correct, and identify how to recognise what a result would look like. Assessment focus: identifying what to measure or compare to answer a science question.
Task: Demonstrate understanding of the pupil reflex of the eye, and apply this to answering questions about sunglasses safety. Extension questions probe understanding of who decides on and applies safety standards. Assessment focus: effect of UV light on the eyes and how it can be mediated by simple sunglasses technology.
