SCIENCE




   Is the set of knowledge that is organized in a systematic way obtained from observation, experimentation and reasoning within specific areas. It is through this accumulation of knowledge that hypotheses, questions, schemas, laws and principles are generated


ENERGY

Energy in the world 

I learn about energy that energy  is the ablity to do work , when you eat the body  breaks down the food and give you energy to work and play or  when yo recieve sun energy in the form of heat and ligth. Kenitc energy and Potencial energy are the main forms of energy . Kinetic energy is the energy that is in motion and potencial energy   is the energy that stored inside the object . Energy cannot be destroyed  not created but can be transform one form of enrgy to another . If  an object is kenetic and potencial is  mechanical energy. Are different types of energy: chemical energy, electrically energy and gravitational energy. Chemical energy is when energy is cause by chemical reactions 
Electrically energy    is  when thers is electricity . Gravitional energy when is motion  cause by  gravity  for example when object falls  to the ground by earth gravity

Problem in the community 



In the city of barranquilla there is a terrible public transport, not taking into account the needs of the passerby and this leads to a discord between the community, among these problems this is about quota in the transportation that do not care how the passenger Just raise the money they offer them and abuse their time. The bad treatment that many give verbally and physically to the passengers this has led to that there are more companies of transport.

the rov can help by design a smart bus which they would have the ability to deduct times for this a great number of these, taking into account all the needs that have

When selecting an energy source for heating a home , consumers try to think about cost. use proportions to determine the area of the solar collector needed to heat a home collector area (ft2) 400 800 1200 1600 2000 2400 living space (ft2) 1200 2400 3600 4800 6000 7200

THINKING CRITICALLY---- DEVELOPING SKILLS

16.  as the principle of conservation of energy tells me not to be destroyed if it does not transform this many times this does not become energy which makes it look for another source to be supplied, this causes you to worry about taking care of the source that proves it, 17, the ambient temperature mainly influences the bodies in the middle where we are located, the hot water has an altered temperature since this is not the norm of this and the same way the cold, which causes that at some point this is stabilized with the middle. 18. is a potential energy since they are in motion. 19. 20. 20. In all heat transfer mechanisms, the cooling rate of a body is approximately proportional to the temperature difference between the body and the surrounding medium. This fact is known by the name of law of cooling of Newton. 21. a- halfways down - kinetic. b halways up - potencial energy - c highest point - potencial - d . lowest point - kinetic

WHAT I LEARN

WHAT I LEARN  KINETIC THEORY OF MATTER  is the energy moving  particle in constant motion called kinetic theory of matter  . state of matter are liquids , gas, solids  , matter is anything that takes up space and has mass Atoms  The atoms are the smallest particle that makes up a given type . Two atoms of hydrogen form water molecule  most matter is made of atoms that  invisible  and cannot see and touch . Matter in Motion   the constant irregular of particles in air . Robert Brown   comes the Brownian motion that  the idea   that the particles  of all matter are in constant  , random motion that is  no as  kinetic theory of matter TEMPERATURE AND HEAT   When particles moved  fast are in heat} When particles not moved are cooled
