One of the big problems in Barranquilla is the trash. We see trash in any place, and that is not good because we are affecting the nature and our city. In my opinion I would design a robot that help with this, I will put te robots in the most affected paces of the city. This robot would have a special sensor that every time it identifies trash it will immediately clean it up and put it in a trash can. In the water it will be a machine like a net and because water is always moving it will catch the trash people leave in the water. Also to stop this people have to put of their part to be better and to care about nature.

In the videos they say that energy is the ability to do work.Gas has energy and energy can be stored.They talk about a lot of types of energy, they say that the light works with electrical energy, then they show fire and that it is produced by heat energy, they say that kinetic energy is de energy of motion and potential energy is the one that not comes from motion. they also say hat energy cannot be created or destroyed but it can transform from one form of energy to another. when an object have potential and kinetc energy at the same time it is mechanical energy, chemical energy is realized when food is broken down, gravitational energy is the energy caused by gravity. energy that comes from the sun is solar energy ,they show an example of the panels and they say that at the day the panels store the energy of the sun and at night they used it and hydel energy is the one that comes from water.
