Question 1 (1 point)
The picture shows the pinwheel that Stephen has in his backyard.
Sometimes Stephen will see his pinwheel spinning, but other times it does not spin. Which statement best explains what makes his pinwheel spin?
a
The colors on the wheel repel one another, causing it to turn.
b
Energy from the ground shakes the wheel and makes the pinwheel move.
c
The Sun heats up the pinwheel, causing it to turn.
d
Energy from the wind pushes on the wheel and makes the pinwheel move.
d
Energy from the wind pushes on the wheel and makes the pinwheel move.
d
Energy from the wind pushes on the wheel and makes the pinwheel move.
The correct answer is (d) Energy from the wind pushes on the wheel and makes the pinwheel move.
To determine the correct answer, we can use our knowledge of how pinwheels work. Pinwheels have blades or vanes that are angled, creating a shape similar to an airplane wing. This shape allows the wind to push against the blades and create a force that causes the pinwheel to rotate.
To verify this, we can conduct an experiment by blowing air towards a pinwheel and observe if it spins. By repeating this experiment multiple times, we can confirm that it is the wind that makes the pinwheel spin.
Therefore, the correct answer is (d) Energy from the wind pushes on the wheel and makes the pinwheel move.
