Sample questions

A few real prompts from the game to help you choose an activity for your class.

01
What makes sound?
- an object vibrating
- air rushing out of an object
- hot air around an object
Read the explanation
Sound comes from something vibrating, and travels through the air to the ear.
02
What can sound travel through?
- only air, not water
- air, water and solids
- air and empty space
Read the explanation
Sound travels through air, water and solids, but not through a vacuum.
03
What makes a sound loud or quiet?
- the speed of the sound is different
- the size of the object is different
- the size of the vibration is different
Read the explanation
Loudness depends on how big the vibration is - a stronger vibration is louder.

Game teaching guide

What children will practise

About sound: it comes from vibration, travels through air, water and solids, loudness depends on how big the vibration is, pitch on how fast it vibrates, protecting your ears, and why space is silent. Question 1 matches indicator ว 2.3 ป.1/1 (how sound is made and travels); questions 2-6 are Grade 5 content (ว 2.3 ป.5/1-5/5), best treated as enrichment.

What's in the worksheet

6 questions, multiple choice with three options each - Sound comes from an object vibrating - Sound travels through air, water and solids - Loud or quiet depends on the size of the vibration; high or low on how fast it vibrates - Space is silent because there is no air for sound to travel through

How to use it in class

Play it after making cup telephones or plucking rubber bands, about 5-6 minutes in teams. One rubber band demonstrates both questions 3 and 4: pluck hard and soft for loudness, stretch it tighter or looser for pitch. For question 2, have a child press an ear to the desk while a friend taps gently at the far end. You can link it to a class and record it in the gradebook. Question 4 uses ความถี่ (frequency), a hard word for Grade 2; explain it simply as vibrating fast or slow.

Common sticking points

- Questions 3 and 4: swapping size of vibration and how fast it vibrates, since both ideas are new and sound alike. Demonstrate each separately with a rubber band. - Question 2: choosing only air, never having listened underwater. Try the ear-to-desk test. - Question 6: choosing no gravity, linking space with floating. Stress that sound needs something to travel through.
