Is pluto still a "planet"?

No, pluto used to be considered a planet but now it is considered a dwarf planet.

Explanation:

Pluto was founded in 1930, and was added to be one of the planets.  After Eris was discovered, scientists had to make up a decision.  Whether Eris was going to be the 10th planet in the solar system or not.  Since Eris was similar to Pluto, they started to question whether Pluto was even considered a planet.  Scientists then made up rules that would determine if something was a planet or not.  A new category was created, dwarf planets.  

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
