Cambridge Primary (1-6) · Unit 3: Light and shadows

Question 14

These children were asked ‘Why does the Emergency sign have translucent glass with a bright lamp behind it?’ They answered like this:

- Sofia: ‘It keeps the sign cool.’
- Marcus: ‘Because the glass might not break.’
- Zara: ‘Because the letters stick to it.’
- Arun: ‘It makes the sign bright but the bright lamp is kept out of our eyes.’

Which child is right? Why?
