TECHNOLOGY AND DIGITALIZATION 2nd ESO

 Thecnology is changing our lives and it will be doing in the future. In this video you can think about the changes and the future changes to be prepared of all of them.

  Technology and living conditions All technological activities as a whole has consecuencies, therefore the manucfacturing a new technical object, or modifaying one existing object it is important to consider its contribution to society. Technological and sustinable  developtment Tecnological development can have negative consecuences for the enviroment. We tend to use non-reweable natural resourses and weath the Earth and causes changes in the ecosystems, even leading to the extintions of animals and plants spices or the air and water pollution. Others sustances increses the greenhouse effect such us CO 2 . We produce it when we burn anything. Sustinable developtment tries to make the quality of live by technological advaces compatible with respect for enviroment, seeking ways to minimize the enviromental impact of technology. Keys to    sustinable  developtment The keys to achieving sustinable development are: Energy efficency, that is energy saving, which pre...

It is vey difficult to define what Technology is. We know that it helps us to adapt to our enviroment and overcome our limints. However is difficult to define. Although we can define well what Technology is, we know its role during the history. Because of this we are going to analyze its role and importance during the developtment of our society. This video helps us undestand better    ACTIVITIES 1.- DEFINE TECHNOLOGY USING YOUR OWN KNOWLEDGE OR SEARCHING FOR MORE INFORMATION ON THE INTERNET. 2.- DO A TEMPORARY LINE WITH THE MAIN TECHNOLOGICAL EVENTS DURING THE HISTORY.

We should do some practices with ARDUINO board. It is true that as programming language ARDUINO is very dificult. This is the reason why we are going to use bitbloq that is very similar to SCRATCH and it let us to learn also ARDUINO language. This video shows three practicises and how you can do in bitblog. I hope you enjoy it and the practiceses. ACTIVITIES 1.- Do the practicises   2.- Take photos and do videos HOMEWORK 1.-  Write a report in which include photos and the videos. 2.- Can you include any of these praticises in a project?

ARDUINO, is not just a controller card, it is an open hardware electronic platform for the creation of prototypes. It allows connecting both analog and digital sensors and actuators, both analog and digital. This is the link ARDUINO The appearance of an ARDUINO ONE card (the most used) is the following: The fundamental part is the ATMMega328 microprocessor. But it also has 6 analog inputs and 14 digital inputs / outputs. 2 power pins (5 and 3.3 V) a reset button and the probability of external power or USB port. Each contact provides 40 mA maximum and we can connect circuits using Shield or Protoboard plates.              The BQ company has used this controller card as a base and, by making some changes, has created its own BQ ZUM and FREDUINO control cards. Its use is more simplified.               In addition to having the card,...

Robots are machine that easies our live. We have create to do monotonous and danger task such as paint or explorer a planet. However they never will reach the human conditions. Our future will be plenty of these machines, so you should know how they work and how you can use. For this purpouse you need some knowledge.

      Although the term programming is associated with the world of computer science and computers, it is much broader. A program is simply a set of commands (actions, simple tasks) ordered in a certain sequence to achieve a certain action. Therefore, it is possible to create a programming based on mechanical elements that can be transformed into a program that can be understood by a computer or not.          The human being has been able to overcome his own limitations because of his ability to use tools. The tools have allowed us to create machines. One of the machines that has given us a greater advance has been the computer. The computers have two main systems the hardware (physical system) and software. The hardware is electronic type and is only sensitive to step or not current. This behavior can be modeled mathematically by the so-called binary codes. Binary numbering only uses zeros and ones. In this way the ...

WE USE CIRCUIT IN OUR PROJECTS, SO WE NEED TO BE SURE ABOUT THEM. THIS IS THE MAIN REASON WHY WE TEST THEM BEFORE USING IN THE PROJECT. FOR THIS PURPOUSE WE USE THE PROTOBOARD. AND TO MEASURE VOLTAGES AND CURRENT WE USE THE POLIMETER. IN THE VIDEO IS SHOWN HOW TO USE THEM ACTIVITIES Using this document do a report and upload to your SCHOOLOGY account DOCUMENT HOMEWORK DO A MENTAL MAP OF THIS UNIT

We use electric energy because is easy to  produce and to transport. However it has to be transform into others types of energy. To do this we use the electric machines. It is necesary that we know how they works its parts and the science principles of them. this video shows this things. ACTIVITIES 1.- Study a motor and  taking photos explain how it works 2.- Do you transform a motor into a dinamo? How? 3.-  Desing a circuit capable of change the sense of a motor by using a switch?

A lever is a simple machine which has a rigid bar. This bar can pivot on a point of support calls fulcrum. It its used to lift load by applying force to a point on the bar. The applied force calls efford, whereas the load to be lifted is resistance. The law of lever, which is a consecuence of dynamic equilibriul is E * Ae = R * Ar. The grater distance between the applied force and the fulcrum, the less efford. This video shows what you must learn about levers. ACTIVITIES 1.- Classified this levers and indicate the efford, flucrum and resistance Scissors, nutcracker, tweezers, wheelbarrow, bottle opener, fishing rod, swing 2.- Imagine you have a lever which one arm double to the other arm. You want to put 20 Kg on one arm and 40 Kg on the other. Where should you position the loads to keep the lever balanced? HOMEWORK Sumarize the lesson
