Shadows - Self Assessment

The self-assessment on shadows encourages students to reflect on their understanding of why shadows occur and the nature of their appearance. Students are asked to consider if they can articulate that shadows are formed when a shape obstructs light, thereby creating a dark area. Additionally, they must assess their comprehension of the concept that a shadow typically mirrors the silhouette of the object that is blocking the light. This self-evaluation also prompts students to think about whether they can explain the methods by which the size of a shadow can be altered, thus demonstrating a deeper grasp of the relationship between light, objects, and shadows.

The teacher's input in this self-assessment process is crucial for validating the students' understanding and for providing further guidance. The students are encouraged to communicate their knowledge about the formation of shadows due to the blockage of light by an object. They are also expected to recognise that the shadow's shape is generally similar to that of the object causing it. Furthermore, the ability to describe how the size of a shadow can be changed is a key learning objective. The teacher's feedback will help students confirm their understanding or identify areas where they may need additional support or clarification, ensuring a comprehensive understanding of the principles behind the formation and characteristics of shadows.
