Light - Assessment

The Year Six Light Assessment is a comprehensive evaluation of students' understanding of light concepts. The assessment begins with a question that requires students to explain the nature of moonlight, encouraging them to articulate their knowledge about natural light sources. Following this, they are tasked with categorising objects as either luminous or non-luminous by drawing lines, demonstrating their ability to distinguish between objects that emit light and those that do not. The test then prompts students to define darkness, a fundamental concept in the study of light.

Further questions delve into the properties of light, such as its mode of travel, which students must describe succinctly. Practical application of their knowledge is assessed through drawing tasks where they must illustrate how light rays enable a person to see a television and how a reflection of a candle appears in a mirror. They are also challenged to draw a ray diagram to show the workings of a periscope, a device that uses reflections to see over obstacles. The assessment covers the human eye's anatomy, asking about the type of lens it contains and requesting ray diagrams to show how light behaves when it passes through different types of lenses. Students must also explain the meaning of 'opaque' and describe what happens when light encounters an opaque object. The assessment includes an analysis of an experiment conducted by fictional students Blake and Hunter, which involves observing the shadows of different shapes and deducing conclusions about the properties of shadows. The test concludes with questions regarding the effects of changing the conditions of the experiment by using translucent shapes and asking for the definition of 'translucent'.
