Read the explanation
Light falls on the object and bounces back into our eyes.
02
Which surface reflects light best?
- sandpaper
- a mirror
- black cloth
Read the explanation
A smooth shiny surface like a mirror reflects light best.

Game teaching guide

What children will practise

Light and seeing: we see because light reflects into our eyes, mirrors reflect well, light travels in straight lines, refraction, the bent-looking spoon, and rainbows. Questions 1-3 match indicator ว 2.3 ป.2/1 (how light travels and how we see); questions 4-6, on refraction and rainbows, go beyond the primary indicators and work as enrichment.

What's in the worksheet

6 questions, multiple choice with three options each - We see because light reflects off objects into our eyes (distractor: our eyes send light out) - A mirror reflects best; light travels in straight lines - A spoon in water looks bent because light refracts at the surface - A rainbow forms when water droplets split white light into colours

How to use it in class

Play it after a dark-room light activity such as shining a torch through a row of holes in card, about 6 minutes in teams. After question 5, give each team a clear glass of water and a pencil to look for themselves. For question 6, on a sunny day, spray a fine mist with your back to the sun to make a real rainbow. ตัวกลาง (medium) in question 4 is hard for Grade 3: explain it as what the light passes through, like air or water. You can link it to a class and record it in the gradebook.

Common sticking points

- Question 1: choosing our eyes send light out, a belief children often hold. Ask: if eyes gave out light, why can't we see in a dark room? - Question 5: choosing the water bends the spoon because it really looks bent. Lift the spoon out and show it is still straight. - Question 4: confusing refraction with reflection, both new words. Separate them: reflection bounces back, refraction passes through but turns.
