4th grade Science practice sheet
Minnesota K-12 Academic Standards · from Gradelings · Name: ______________________
Question 1
Some First Peoples' oral histories tell about floods and rivers changing course long ago. What does this show?
🗣️- the land never changes
- oral histories hold long-term knowledge of the land
- stories are never about real places
oral histories hold long-term knowledge of the land
Hint: Knowledge passed down over many generations can remember changes to the land from long ago.
Question 2
What force pulls everything toward the Earth?
🍎- gravity
- pollen
- friction
- electricity
gravity
Hint: Gravity is why things fall down when you drop them.
Question 3
You can only use two magnets. That is a…
- constraint
- pole
- criterion
- prediction
constraint
Hint: A limit.
Question 4
Which trait is affected by the environment?
- A flower's petal shape
- A bird's beak type
- A dog's number of legs
- A plant's height with little water
A plant's height with little water
Hint: Water and food affect growth.
Question 5
A volcano puts ash into the air. Which systems interact?
- Hydrosphere only
- Biosphere and hydrosphere
- None
- Geosphere and atmosphere
Geosphere and atmosphere
Hint: Rock enters air.
Question 6
Which helps save energy at home?
- Run water all day
- Open the fridge often
- Leave the TV on all night
- Turn off lights you aren't using
Turn off lights you aren't using
Hint: Use less.
Question 7
Breaking rock into smaller pieces is called…
- weathering
- melting
- deposition
- erosion
weathering
Hint: Rock wears down.
Question 8
A valley shaped like a V was most likely carved by…
🏞️- the wind
- a glacier
- a river
a river
Hint: Rivers cut narrow V-shaped valleys. Glaciers scrape out wide U-shaped valleys.
Question 9
To reduce damage from flooding along a river, people can…
🌊- build barriers and keep homes away from the riverbank
- cut down trees on the bank
- remove all dams
- pour more water on the banks
build barriers and keep homes away from the riverbank
Hint: Flood forces from fast water are hard to stop; planning where to build helps keep people safe.
Question 10
In engineering, constraints are…
- limits like time, cost or materials
- what the design must do
- the winner
- a kind of force
limits like time, cost or materials
Hint: What holds you back.
Answer key
- 1. oral histories hold long-term knowledge of the land (Wind, Water & Ice)
- 2. gravity (Pushes, Pulls & Forces)
- 3. constraint (Magnet Inventions)
- 4. A plant's height with little water (Traits & Variation)
- 5. Geosphere and atmosphere (Earth's Systems & Water)
- 6. Turn off lights you aren't using (Energy Resources)
- 7. weathering (Rock Layers & Erosion)
- 8. a river (Wind, Water & Ice)
- 9. build barriers and keep homes away from the riverbank (Pushes, Pulls & Forces)
- 10. limits like time, cost or materials (Magnet Inventions)
