Unit 3F: Light and shadows

QCA

Objectives

Section 1: Introduction
Children should learn:

View related activities and outcomes

Section 2: Making shadows
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

View related activities and outcomes

Section 3: Sunlight and shadows
Children should learn:
  • that shadows are formed when objects block light from the Sun
  • that shadows are similar in shape to the objects forming them
  • that shadows of objects in sunlight change over the course of the day
  • to make and record observations of shadows and to try to explain these using knowledge about light

Section 4: How shadows change through the day
Children should learn:
  • that shadows change in length and position throughout the day
  • to measure the length of the shadow in standard measures
  • to make a table and bar chart to show how the length of the shadows changes during the day

Section 5: Where does the Sun shine?
Children should learn:
  • to record and identify a pattern in the observations of the Sun
  • that the Sun appears to move across the sky during the day

View related activities and outcomes

Section 6: Observing the position of the Sun
Children should learn:
  • that when the Sun is behind them their shadow is in front
  • that the Sun appears to move across the sky in a regular way every day
  • that the Sun appears highest in the sky at midday
  • that the higher the Sun appears in the sky the shorter the shadow

Section 7: Showing how the Earth spins
Children should learn:
  • that the Sun does not move, its apparent movement is caused by the spinning of the Earth on its axis

Section 8: Sundials
Children should learn:
  • that shadows can be used to tell the approximate time of day

View related activities and outcomes

Section 9: Light and different materials
Children should learn:
  • that opaque objects/materials do not let light through and transparent objects/materials let a lot of light through
  • to use their knowledge about light and shadows to predict which materials will form a shadow and to plan how to test this
  • to compare the shadows formed by different materials and to draw conclusions from their results
  • to decide whether the results support their predictions and to use knowledge about shadow formation to explain the conclusions
