Lesson details
Key learning points
- A shadow is a dark shape formed when light is stopped or blocked by an object.
- Opaque objects do not allow light to travel through them. Translucent objects let some light through.
- A shadow can be different sizes depending on the distance of the object from the light source.
- Shadows are dark where the light has been blocked and they do not show the features of the object.
- Shadows of objects are not the same as reflections of them.
Keywords
Shadow - A shadow is formed when an opaque object blocks out the light.
Light source - An object that is a light source produces its own light.
Opaque - Light cannot pass through objects that are opaque.
Features - Features are interesting characteristics or details of someone or something.
Reflection - Reflections of objects are images that form when light bounces off a shiny surface.
Common misconception
Shadows only form in bright light; shadows and reflections are the same thing; a shadow shows the features of an object.
Children will explore shadow making and images/examples will be used to highlight the key features of shadows and reflections.
Equipment
Torches and objects with which to make shadows.
