You misunderstood.
The scientists went the other way. There are 3 new items that are now planets. And pluto is still a planet
See pluto is small, and not very big. It's the size of our moon. So there was talk about removing it's planet status.
But instead what they did was say. Anything revolving around the sun, and big enough to be round is a planet.
So Pluto's brother Charon -sort of twin planet to pluto.
Also a former astroid near Saturn and one other somewhere are now all planets.

While Pluto is still technically a planet - it is now no longer part of the list of "classical" planets. All of which, have a circular or slightly elliptical orbit around the Sun on the same orbital plane. Pluto has a highly elliptical orbit that is tilted comparied to other planets.
Pluto is also classifed as an icy dwarf planet or "pluton". Which are planets that are generally smaller than the Moon, and have a tilted, elliptical, orbit that is most outside the orbit of Neptune.

Pluto is a small planet that is far away. It goes around the sun in a strange circle. It was discovered in 1930. Size matters to some astronomers, who have just talked about it being called a dwarf planet. Sometimes large groups of scholars get together to talk about if some thing is real or not. It could be a planet or a play by Shakespeare. Different points of view.
two word answer - too small

They have come up with a new definition of what a planet is. With the exception of Pluto all the planets revolve around the sun in a circular path. Pluto moves in an eliptical (more oval) path. Which means at certain points in Pluto's revolution around the sun, Pluto is actually the eighth planent and Neptune is the nineth. Because of this scientists now say that Pluto is not a planet. It is now under the new heading of dwarf planets.

In addition to the other (excellent) reasons posted, Pluto didn't fit in with the other planets. The first four planets (five, if you include the planet that became the asteroid belt) are small, rocky objects. The next four are large, gaseous objects. Pluto, is a small, rocky object, out there with the gas giants. It doesn't fit in where it is. Therefore...

From what I've gathered, Pluto doesn't travel along the same orbital plane around the sun as the rest of the planets.
Another words, its orbit is too slow and erratic. The other worlds, Mercury through Neptune, travel on a consistent XY axis plane at a consistent speed.
Pluto is supposedly one of hundreds of other similar objects that can be found outside of our solar system.
Hope this is in plain enough english for you...

Because Pluto does not orbit the sun in a regular pattern, or at least that is what I think. (I still call it a planet)

pluto is not really a planet, its just another big rock
