presentation about energy by claudia hernÁndez and mario cortÉs

THE ENERGY CHANGE

The energy can change

The energy can change because the matter can´t be destroyed, it only can transforms. An example, an ice with a hot teperature they melt.

CIRCUITS

THE FIRST CIRCUIT

In this circuit the electrical energy transforms into light energy because it pass through the copper to the light bulb and it iluminates them. Then a little bit of the light bulb´s energy transforms into electrical energy to the switch.

THE SECOND CIRCUIT

In this circuit happen the same as the other circuit, but in this circuit the light bulb iluminates less becose the energy repart in more thinks.In this circuit the switch doesn´t controle all the energy of the lights bulbs becose the energy of the switch come frome the light bulb.

THE THIRD CIRCUIT

In this circuit happen the same as the second circuit, but then the energy of the second ligth bulb transform into kinectic energy.In this circuit the ligth bulbs iluminated less and the ventilator moves more slowly.

THE FORTH CIRCUIT

In this circuit the electrical energy transforms into kinectic energy and then the kinectic energy transforms into electrical energy.In this circuit the switch doesn´t controle all the energy of the ventilator.

THE LIGHT AND THE WATER

WHAT THINGS CAN DO THE LIGHT?

The light can disperse in seven colors

The light can make shadows

The light can travel in all diractions

EXPERIMENTS

FIRST EXPERIMENT

In this esperiment we have a bottle with water and a torche.We are going to transform this bottle in to a waterfall, the waterfall is going to be an other color.

SECOND EXPERIMENT

In this experiment we have a glass with water.In this experiment we are going to sign the glass in diferent positions and we look the reaction of the ligth.

THE THIRD EXPERIMENT

In this experimetn we have a glass of water and a coin.
