Question 1
Why do helmets protect you in a crash?
- They make you faster
- They absorb energy of the hit
- They stop gravity
- They add energy
They absorb energy of the hit
Hint: Soft padding takes in energy.
Question 2
A floating duck bobs up and down as waves pass. The water mostly moves…
- in a straight line away
- nowhere
- to shore with the wave
- up and down
up and down
Hint: Waves carry energy, not the water.
Question 3
A bulb that changes electricity to light also gives off some…
- sound waves only
- heat
- magnetism
- chemical energy
heat
Hint: Touch an old bulb: warm.
Question 4
A fair test changes…
- only one thing at a time
- everything at once
- the answer
- nothing
only one thing at a time
Hint: Keep the rest the same.
Question 5
Which kind of force can change a flat piece of clay into a ball?
🧱- squeezing and pushing
- a magnet
- a smell
- gravity only
squeezing and pushing
Hint: Pushing and squeezing change shape.
Question 6
In rock layers, the oldest layer is usually at the…
- middle always
- bottom
- top
- side
bottom
Hint: Layers stack up over time.
Question 7
Which resource is renewable if we plant new trees?
- Natural gas
- Oil
- Coal
- Wood
Wood
Hint: Trees can regrow.
Question 8
Which hazard can a volcano cause?
- A blizzard
- Falling ash
- A drought
- A tornado
Falling ash
Hint: Ash can fall far away.
Question 9
When two cars bump, you hear a sound. The sound shows…
- nothing happened
- energy grew
- energy disappeared
- some energy turned into sound
some energy turned into sound
Hint: Energy changes form.
Question 10
Bigger ocean waves have more…
- energy
- color
- fish
- salt
energy
Hint: Big waves can move rocks.
