It's due to magnetic activity, every 11 years the sunspots explode and begin to form elsewhere.

How can you use sunspots to tell that the sun is rotating on its axis?
they move across the sun's surface :)
Sunspots are temporary disturbances in the suns what?
Sunspots are temporary disturbances in the sun's photosphere. They appear as black spots because they are significantly cooler areas cause by magnetic activity on the sun. They can be various sizes and move across the sun at various speeds before disappearing.
What can you conclude from your observations of sunspots?
Sunspot are never in a pattern. Sunspots move on the sun at the same speed.
Why does the sun move across the sky in short words?
The Sun doesn't: "move across the sky" Earth revolves around the Sun which is why it appears to "move across the sky".
Are sunspots hotter or colder regions of the sun?
No, sunspots are cooler than the photosphere.
What does the way sunspots travel across the face of the sun indicates about the way the sun rotates?
Suspots don't actually MOVE across the face of the Sun; a sunspot pretty much stays put. So when we see sunspots APPEAR to move, what we're actually seeing is the rotation of the Sun itself.

How did scientist find that the sun rotates on its axis?
Watching the sunspots travel across the face of the Sun.
What are some things that aren't true about sunspots?
sunspots move from left to right across the sun's surface. sunspots weigh 3.475 kg
What evidence proves that the sun rotat es on its axis?
We can see sunspots travel across the face of the Sun. Sometimes, for long-lasting sunspots, we can see the same ones 28 days later when they roll around again as the Sun spins.

How the sun moves when the sunspots move from WEST TO EAST?
By the Sun's rotation.
What can you conclude from your observations of sunspots?
Sunspot are never in a pattern. Sunspots move on the sun at the same speed.
Do convection currents carry sunspots across the surface of the sun?
False
What would happen if the sun rotated east to west?
Nothing much. The rising and setting of the Sun appears to happen because the EARTH is rotating, and we don't really notice much about the SUN spinning. It does, of course, and astronomers track sunspots across the face of the Sun as it spins (when there are sunspots, which there mostly haven't been in the last 3 years or so).
