While loops

Hi!
Today I learned while loops on Karel. A while loops makes the thing you typed go over and over again and makes the stuff stop when something you typed is true. A while loops look like this:

 while (frontIsClear( )){
            putBall( );
            move( );
}

This week i am doing Boxcar Rumble and A Day at the Carnival for piano.

I learned on How Things Work an object that is in motion stays in motion and if you push against a skater and I push against the same skater at equal force the skater will not go anywhere.

In the Story of the World I learned that when people first made pyramids they were white. And the Romans called the Visigoths, Vandals, Huns, Goths and Ostrogoths barbarians.
