Grade 4 Science practice sheet
New Brunswick Curriculum · from Gradelings · Name: ______________________
Question 1
A drought dries up a pond. What happens to the animals that live there?
🏜️- they get more food
- they grow gills
- nothing changes
- many have to move or may not survive
many have to move or may not survive
Hint: Water is a necessity for pond life.
Question 2
Why is a food web a better picture of nature than one food chain?
🕸️- it is only for plants
- most animals eat more than one kind of food
- it has fewer animals
- it is smaller
most animals eat more than one kind of food
Hint: Real communities have many links.
Question 3
Which light source gives off light but very little heat?
🟢- the Sun
- a campfire
- a candle
- a glow stick
a glow stick
Hint: A glow stick makes light with a chemical change, not by burning.
Question 4
A fire alarm uses a loud, high-pitched sound. Why?
🚨- it is quiet
- it is pretty
- it is easy to notice and warns people of danger
- it makes the fire go out
it is easy to notice and warns people of danger
Hint: Sound is a useful warning signal.
Question 5
Does it help a habitat or harm it? Tap an item, then tap its basket.
Sort into: 💚 helps habitats · ⚠️ harms habitats
- 🌉building a wildlife crossing over a highway
- 🪺putting up bird nest boxes
- 🛢️dumping chemicals into a river
- 🌳planting native trees
- 🪓clearing a forest and leaving it bare
- 🅿️draining a wetland for a parking lot
💚 helps habitats: building a wildlife crossing over a highway, putting up bird nest boxes, planting native trees · ⚠️ harms habitats: dumping chemicals into a river, clearing a forest and leaving it bare, draining a wetland for a parking lot
Hint: Restoring wetlands and putting up nest boxes help. Pollution and clearing habitat harm.
Question 6
Put the food chain in order. Start with the producer.
- 🦢heron
- 🌾grass
- 🐸frog
- 🦗grasshopper
grass → grasshopper → frog → heron
Hint: A food chain starts with a producer. Each arrow shows energy moving to the animal that eats it.
Question 7
Which surface reflected the most light?
Temperature after 10 minutes in the Sun (°C) - black paper
- white paper
- foil
foil
Hint: It stayed the coolest.
Question 8
Why do you see lightning before you hear thunder?
⛈️- sound is faster than light
- lightning is quieter
- light travels much faster than sound
- thunder is made first
light travels much faster than sound
Hint: Light reaches you almost instantly.
Question 9
A conservation group wants to protect a wetland for birds. A farmer wants to use the land. This shows…
👥- different perspectives about land
- that wetlands have no value
- a map problem
- only one view matters
different perspectives about land
Hint: Each side has reasons.
Question 10
Where does a plant get the energy to make food?
☀️- from the Sun
- from the soil
- from the wind
- from the rain
from the Sun
Hint: Plants turn light energy into food.
