Inkscape

 Inkscape is a professional vector graphics editor for Windows, Mac OS X and Linux. It's free and open source.

You can download the program through this link: https://inkscape.org/es/

After having done the practices in class, you must create a logo related to your name.  The more elaborate your work is, the higher your mark will be.

When you finish your work, you have to publish it in your blog. To do that, first you have to turn your logo into a bit map image. When you create an image with Inkscape, the format you get is .svg. If you want to change it, you have to go to Archivo/Exportar mapa de bits, write the name of your file, choose a folder to save it and click on Exportar. This way you get a .png file, which you can use in your blog as an image file.

Audacity

This is the task you have to carry out after finishing all the practices:

You must record a story in your voice. The news should last at least 10 seconds, and must include a greeting, the news itself and a farewell. In addition, there will be a music entry (with cross fade in effect), background music while the news is narrated and a music output (with cross fade out effect). You should apply 3 effects to the voice while narrating the story. You must save your work as MP3 and post it on your blog.

Audacity is a free audio editor and recorder. You can download this program in http://audacity.es/

To save your work as a mp3 file you need to download a especial file that allows some programs to encode mp3 files: the LAME library. You can go to http://lame.buanzo.org/ and download that file. Then, the first time you try to save your work as a mp3 file, Audacity will ask you where you have stored the file LAME. Tell the program where this file is (probably in the folder downloads) and install it. Next time you want to save your sound as a mp3 file, you will be able to do it directly.
 

3º ESO projects

Here you can see  videos with some of the projects students of 3º ESO have made. The requirements were to design and build something automatic that includes mechanisms.

The first video shows an automatic barrier that is closed all the time unless an object stays in front of it. At that point, the barrier opens and remains open till the object has gone. Then it closes again.
        

María, Francisca, Alba, María and Sergio have used the circuit you can see below. The sensor is a LDR, located on the floor in front of the barrier. When we cover the LDR, the transistor changes from cut off into saturation. That way we activate the relay connected to the collector, so that the way the motor rotates changes. When the barrier presses the limit switch at the end of the opening movement, the motor stops.

If the LDR is not covered, the transistor returns to cut off, so the electromagnet of the relay doesn't attract the changeover switches. Then the way the motor rotates changes, and the barrier closes. At the end of the closing movement there is another limit switch that makes the motor stop.

Silvia, Francisca, Beatriz, Alba and Amara have made a similar project but in this case the motor rotates in the opposite way.

Some other groups have chosen an easier circuit, the one you can see below, with a LDR activating a motor but only in one direction.

Jorge, Roberto, Nico, Tobías and Jorge have used this circuit to make up a car that moves only when it receives light.

 

  Rodrigo, Jorge, Ángel, Lidia and Alina have used also the same circuit to build a mill that rotates when it receives light, but not when we cover the sensor placed on the roof.

 

Blender

What do you think about this animation Desireé and Noelia have made? They have created it from scratch

Apps for Good

We are participating in the Apps for Good project with 4º ESO students in Computering. They will be working in teams, trying to solve a social issue by designing and creating an app for mobile phones, as if they were part of a startup.

Second project results for 1º ESO

Here you can see some pictures with the objects that 1D and 1E students have made after working in their second project, which was related to structures.

Blender

Blender is a free 3D graphic software we use in Computering to sculpt 3D objects and then create animated films with them.

 In this video students have created a church, a house and a car. Then they have animated the car to make it move around the buildings.

Second project for 1 ESO

Design and plan a structure. It must support a 2 kg load at 20 cm height. You can only use paper and cardboard.

Electronics

In this lesson we have our first contact with semiconductor materials. These materials are used to make electronic components, such as the diode and the transistor. With transistors we can make up automatic circuits in which we use a sensor to activate an electric receiver.

In this video we use a light sensor (ldr) to make a light bulb work. When the sensor detects light, the light bulb doesn't shine. When we cover the light sensor, the light bulb shines.

In this second video we use a temperature sensor (ntc) to make a light bulb work. If we don't touch the sensor, the environmental cold makes the light bulb shine. When we touch the sensor, our heat makes the light bulb remain without shining.

First project results from 1 ESO

Here you can see some pictures with the objects that 1D and 1E students have made after working in their first project, which was related to wood.
