Hour of Code

The las assignment we have done in Technology subject has been Coding. It has been an extra activity before Christmas and also we've done this activity because two weeks ago was the Hour of Code.

The hour of code is a global movement that has arrived to millions of students in more than 180 countries in the world. Any person, in any place in the world, can organize a Hour of code.

Programming is definitely important. Lots of universities; thousands of professors; students and practitioners teaching, learning and practicing the coding are enough people to verify that coding is really important.

The main reasons for this are: 


  • To interact with machines and computers
  • To harness the power of computing in all human endeavour
  • To automate tasks
  • To create intelligent machines, robots, etc.

In my opinion, coding is now ad days really important. First, because without this technique, we wouldn't be able to  "communicate" with machines, robots and other electronic devices. Secondly, because now an important part of the tasks in factories and in jobs that require precision, are done by machines. Without coding, we wouldn't be able to programme the machines to do these tasks automatically. And finally, because we wouldn't be able to make new machines that could be more efficient, cheaper and more precise.

I made my Hour of code. It was an amazing experience because I had never programmed a machine to do things, and I did it for the first time. For my surprise, it was very easy and simple, and the robot did exactly what it was asked for. There were different levels, and each level was more difficult. The las level asked you to do your own game. It was very interesting. I think it was important for me because it was a pretty good introduction to the world of coding and programming.

Water filter projects

During these last weeks, in Technology subject we've been building some water filters in order to try to solve one of the main ecological problem now addays: the water scarcity.
I've learned many things from my project and from my classmates' presentations.
97% of the total water in our planet is in the sea, so it's salty. A 2% of the water is located in glaciers, so we can't drink it. And only a 1% remaining is fresh water, and a lot of this 1% is polluted,. There are many countries that have large quantities of polluted water, like Zimbawe, Republic of Congo, Senegal, Qatar, Singapour, Cyprus... Polluted water can also cause illesses like Typhod fever and Polyomielitis.










To build this water filter we've used very simple materials. As filters we have used stones, cotton, gauzes and sand, in order to not allow dirt pass through. We've used a plastic bottle of 1,5 l as a container, and the stopper of the bottle as a funnel to carry fresh water to the container below.






                           


Stones Sand Bottle



During the process we had some problems:

-We needed to take out all the sand because it went down the bottle and mixed with stones. We put a gauze between them in order to separate them and solve this problem.


While making this project I've learned many thing and I think I've improved my knowledge about water scarcity.
