Room 6 Science
We are learning about forces and motion.  We are learning to think like / as scientists. Today we used tracks and marbles to experiment what happens when the marbles started on different places on the track.  We learnt about POTENTIAL ENERGY, the energy an object has because gravity is pulling on it.  We also learnt about KINETIC ENERGY, the energy that an object has when it is moving.   We converted the potential energy into kinetic energy by letting it roll down the track.  We observed that it then rolled across the carpet and then finally stopped.  Our question was "Why did it stop?"  Children in the class have lots of ideas.  We will do other experiments to discover more.
