4th grade Science practice sheet
Alaska content standards · from Gradelings · Name: ______________________
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 surface reflected the most light?
Temperature after 10 minutes in the Sun (°C) - foil
- black paper
- white paper
foil
Hint: It stayed the coolest.
Question 3
Put the steps of hearing in order.
- 🦴tiny bones in your ear vibrate
- 🥁your eardrum vibrates
- 👂sound waves enter your ear
- 🧠a nerve sends a message to your brain
sound waves enter your ear → your eardrum vibrates → tiny bones in your ear vibrate → a nerve sends a message to your brain
Hint: Sound waves enter the ear, the eardrum vibrates, tiny bones vibrate, and a nerve sends a message to the brain.
Question 4
How do maple seeds travel?
- They swim
- They are carried by ants only
- They spin like helicopters on the wind
They spin like helicopters on the wind
Hint: Wind seed dispersal.
Question 5
Which sense detects sound?
- taste
- hearing
- sight
hearing
Hint: Ears detect sound.
Question 6
A toaster changes electrical energy into…
- motion only
- heat
- light only
- sound only
heat
Hint: It warms bread.
Question 7
The top of a wave is the…
- base
- trough
- crest
- floor
crest
Hint: The highest point.
Question 8
Which happens faster on a bare hill than on a grassy hill?
- Plant growth
- Erosion
- Rock building
- Fossil forming
Erosion
Hint: No roots to hold soil.
Question 9
Why do plant roots grow downward, even if a seed is planted upside down?
🌱- Roots sense gravity and grow toward it
- Worms pull the roots down
- Roots are afraid of the light
- Rain pushes the roots down
Roots sense gravity and grow toward it
Hint: Roots respond to gravity by growing down, where they can find water and hold the plant in place.
Question 10
Does it give off a lot of heat with its light? Tap an item, then tap its basket.
Sort into: 🔥 light and lots of heat · 🧊 light and little heat
- ✨a firefly
- 🖥️a computer screen
- 🕯️a candle flame
- 💡an LED bulb
- ☀️the Sun
- 🔥a campfire
🔥 light and lots of heat: a candle flame, the Sun, a campfire · 🧊 light and little heat: a firefly, a computer screen, an LED bulb
Hint: The Sun, flames and old-style bulbs give off lots of heat. LEDs, glow sticks and fireflies give off light with very little heat.
