Task: Identify the colours on a taxi sitting under a red streetlight. Assessment focus: Coloured light can be produced by blocking some parts of the spectrum.
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.
This task requires students to indicate, in a table, the invariant properties of four transformations (translation, reflection, rotation, enlargement) of a picture of a traffic light.
