Carbon footprint

the carbon footpint it is  the all of the pollution of the person ain the one year or day

normally the person contaminate in a year 200 or moreCO2, like me:i contaminate more than 200

of CO2 persone,the gass go up and the consequence are: that the gas break the atmosphere

and this proboke that rocks passing the athmosphere. one more thing are that the bad rays of the sun

pass more of the atmosphereand this proboke skin cancer etc.

This is a serie circuit that pass the electricity with the cables to 
to negative and the serie circuit is more easy than the paralele circuit 
is easy because we need 6 cables a the paralele circuit we need more 
than 6 cables

                                       

project

We use the light sensor  to look the black line and go back with 30 of the speed.

We use the sound sensor because the robot catch  a sound to do the robot forward 1 second and repeat this wen cath a sond,and go forwad with a 60 of the speed, And
wen the sound sensor don't cath a sound the robot rotate with a small speed.

technology project

                                                               Boat project

           I am doing the motor and the other people,Albert and Pau the structure and David                   and me the engine. 






My part and David part of the project was the construction of the engine.

           The first thing we did was look for a motor and an interuptor.

                             Then you have to draw the switch cover and put an electric cable on each side.

  Connect a cable to the battery and switch it to the engine.

 You have to open the radio control and connect it on a cable that is loose in the cable of the interuptor.

The structure is made of wood and the sides of the boat placed one a bottle of water on each side.

then we will put our engine structure into the ship and connect in a remote control with an electric cable, to the boat.

there is no need to place an antenna on the ship,we will use two big batteries for the ship.

We will wrap the electric wires so they will not get wet.

It is not easy to do.
