Understanding Facial Proportions
Learning the mathematical guidelines and common ratios for placing features correctly on a human head.
Key Questions
- Explain the standard proportions of the human face and how they guide feature placement.
- Analyze how small adjustments to facial features can dramatically alter an expression.
- Justify the use of guidelines as a starting point for drawing realistic portraits.

About This Topic
Light is a fundamental physical phenomenon that allows us to perceive the world. In Year 3, students learn that light is necessary for sight and that darkness is simply the absence of light. They explore how light travels from a source, reflects off an object, and enters our eyes, enabling us to see.
This topic aligns with the KS2 Science curriculum for Light. It introduces the concept of light sources (like the sun, lamps, or fire) versus objects that just reflect light (like the moon or a table). Students grasp this concept faster through structured discussion and peer explanation as they use 'blackout boxes' to prove that we cannot see anything without a light source.
Active Learning Ideas
Inquiry Circle: The Mystery Box
Students look into a completely sealed box with a tiny viewing hole. They try to identify an object inside in total darkness, then again when a small torch is turned on, proving light is needed for sight.
Role Play: The Path of Light
Three students act as the Light Source (torch), the Object (a book), and the Eye. They use a piece of string to show how light travels from the source, bounces off the book, and goes into the eye.
Gallery Walk: Source or Reflector?
Display images of the Sun, the Moon, a mirror, a candle, and a diamond. Students move around with a checklist to decide if each item makes its own light or just reflects it.
Watch Out for These Misconceptions
Common MisconceptionOur eyes 'send out' light so we can see.
What to Teach Instead
Light must enter our eyes for us to see. The 'Path of Light' role play is excellent for correcting this, as it shows the direction of travel is always from the source to the eye.
Common MisconceptionThe Moon is a light source because it shines at night.
What to Teach Instead
The Moon does not make its own light; it reflects the light from the Sun like a giant mirror. Using a torch and a ball in a dark room can demonstrate how the 'shining' moon is just reflected light.
