Science at key stages 1 and 2 (Year 3)
Unit 3F: Light and shadows
Section 2: Making shadows
|
|
Objectives |
| Children should learn: |
- that shadows are formed when light travelling from a source is blocked
- to make and record observations and to present information in drawing and writing
|
Activities |
|
Outcomes |
|
Children: |
- Let children explore shadow formation using torches and other light sources eg OHP and objects of different shapes and different materials. Introduce children to the idea of light travelling from a source by shining a powerful torch beam through a comb with widely spaced teeth or a cardboard tube and showing that the beam is blocked and doesn't bend round corners. Show that a shadow is formed on a screen. Ask children to record what they see in drawings and writing.
|
|
- recognise that light can be blocked by objects and shadows are formed
- recognise that when light from sources other than the Sun is blocked shadows are formed
|
|
Points to note |
The understanding of shadow formation is an important step towards establishing that light travels from a source.
