  1. False · Looking harder does not make light. With no light to reflect from the toys into your eyes, you cannot see them.
  2. Light reaching your eyes · Seeing needs light reaching your eyes. Looking hard or using bright paint does not replace light.
  3. A switched-on torch · A switched-on torch makes light. The ordinary chair and book reflect light from a source.
  4. The Sun and a switched-on lamp · The Sun and switched-on lamp each make light. A mirror and ordinary wooden toy box reflect light instead.
  5. Light reflects off them into her eyes · The lamp supplies light. Some light reflects off the toys and enters Zara's eyes, making the toys visible.
  6. True · The torch is a light source inside the box. Light does not have to enter from outside when a source is already inside.
  7. No, its surface reflects light from the Sun · The Moon is lit by the Sun. We see sunlight reflected from the Moon's surface.
  8. No, ordinary red paint needs light to be seen · Ordinary bright paint does not make light. Without light reflecting from the ball into his eyes, Tom cannot see it.
