Which plant part do we eat when we eat a carrot?
- seed
- root
- flower
- leaf
root

- cotton thread
- plastic wrap
- milk
clay from the ground
Hint: Earth materials come from the ground.
Question 6
Two magnets push each other apart without touching. This shows a…
🧲- friction
- contact force
- non-contact force
- twisting force
non-contact force
Hint: The magnets act from a distance.
Question 7
Every magnet has two ends. What are they called?
- roots
- edges of light
- wheels
- poles
poles
Hint: They are the north and south ends.
Question 8

🏎️- nothing
- one thing, like the slope
- everything
- the ramp, car and floor
one thing, like the slope
Hint: One changed thing lets you tell what caused the result.
