Question 1
How does the seed travel? Tap an item, then tap its basket.
Sort into: 🌬️ carried by the wind · 🐿️ carried by animals
- 🌳cottonwood fluff
- 🐻raspberry eaten by a bear
- 🐕burdock burr stuck in fur
- 🐿️acorn buried by a squirrel
- 🍁maple key (a seed with a wing)
- 🌼dandelion fluff
🌬️ carried by the wind: cottonwood fluff, maple key (a seed with a wing), dandelion fluff · 🐿️ carried by animals: raspberry eaten by a bear, burdock burr stuck in fur, acorn buried by a squirrel
Hint: Light fluffy or winged seeds ride the wind. Sticky burrs and tasty fruits travel with animals.
Question 2
Which surface had the least friction?
How far the toy car rolled (cm) - carpet
- tile
- wood floor
tile
Hint: The car rolled farthest on tile, so tile had the least friction.
Question 3
Many seeds are carried by wind, animals or…
- glass
- metal
- water
water
Hint: Seeds travel in different ways.
Question 4
Which unit could measure the time something takes?
- meters
- liters
- seconds
seconds
Hint: Time is measured in seconds, minutes and hours.
Question 5
Which is NOT an inherited trait?
- Hair color
- Speaking a language
- Height range
- Freckles
Speaking a language
Hint: Language is learned.
Question 6
A brown rabbit in snow is more likely to…
- be seen by a predator
- find more food
- hide well
- stay warmer
be seen by a predator
Hint: It stands out.
Question 7
Trees planted in a row to block wind are a…
- levee
- windbreak
- dam
- seawall
windbreak
Hint: They slow the wind.
Question 8
Magnets can push or pull without…
- a pole
- moving
- touching
- being near
touching
Hint: A force at a distance.
Question 9
A sunflower turns to face the Sun during the day. This is an example of a plant…
🌻- being pollinated
- reacting to its environment
- making seeds
- changing its life cycle
reacting to its environment
Hint: The plant responds to light by moving.
Question 10
Two magnets push each other apart without touching. This shows a…
🧲- twisting force
- friction
- contact force
- non-contact force
non-contact force
Hint: The magnets act from a distance.
