Question 1
The school bell rings. Put the steps of your response in order.
- ⚡Nerves carry a message to your brain
- 👂Your ears sense the sound
- 🧠Your brain decides what to do
- 🏃Your muscles move you to line up
Your ears sense the sound → Nerves carry a message to your brain → Your brain decides what to do → Your muscles move you to line up
Hint: Your senses notice first. Nerves carry the message to your brain, your brain decides, then your muscles move.
Question 2
Which light source gives off light but very little heat?
🟢- the Sun
- a campfire
- a candle

a glow stick
Hint: A glow stick makes light with a chemical change, not by burning.
Question 3
A fire alarm uses a loud, high-pitched sound. Why?
🚨- it is quiet

- it makes the fire go out
it is easy to notice and warns people of danger
Hint: Sound is a useful warning signal.
Question 4
When you plug in a lamp, what does the electricity do?
- It stays in the plug
- It gives energy for light
- It makes the room cold
It gives energy for light
Hint: Electricity transfers energy to the bulb.
Question 5
Why do many birds fly south in autumn?
- to find snow
- to find food and warmer weather
- to sleep under water
to find food and warmer weather
Hint: Migration is a survival behavior.
Question 6
When two cars bump, you hear a sound. The sound shows…
- nothing happened
- energy disappeared
- some energy turned into sound
- energy grew
some energy turned into sound
Hint: Energy changes form.
Question 7
Computers store information as patterns of…
- colors only
- smells
- rocks
- 1s and 0s
1s and 0s
Hint: Digital code.
Question 8
Rounded river rocks got smooth because…
- they melted
- wind sanded them in a day
- they were painted
- water tumbled them
water tumbled them
Hint: Rocks bump and wear.
Question 9
Crater Lake formed when a volcano called Mount Mazama…

- erupted and collapsed
- grew taller
- turned into ice
erupted and collapsed
Hint: The top fell in and filled with water.
Question 10
Which uses sunlight to make electricity?
- Dam
- Gas stove
- Wind turbine
- Solar panel
Solar panel
Hint: Panels face the sun.
