Making a toy train move

  • Prototypes, Electronics, Learning Through Play, Science is fun

Toy trains and modular train tracks are lots of fun, especially for kids. Connect different pieces of track and create your own railway circuit.

But one kid was wondering, is it possible to make the toy train move by itself? In this episode, we build a simple little train and let it have a run on the track!

Educational Bites: When we push a train, chemical potential energy (from our food/bodies) is converted into kinetic energy (moving hand and moving train).

When the train "runs by itself", chemical potential energy (from the battery) is converted into electrical energy (through the wires), and then into kinetic energy (moving wheels of the train).

Did you notice other forms of energy conversion also? For example, gravitational potential energy and sound energy.
