Welcome to the second year of Tecnology, Programming and Robotics. Here you will find the most important materials needed for this subject.


1) Basics of electicity

We start this very important unit with the BASICS OF ELECTRICITY AND ELECTRICAL CIRCUITS:
a) First, let's find out what atoms and electrons are and how they are related to electricity: Introduction to electricity - Atoms and electrons
b) Second, learn the historical origin of some important electrical concepts and words:

c) And finally, you will be able to design electrical circuits for very different applications when you learn the most important parts they usually have with this "fill in the blanks" activity: Basics of electricity and electrical circuits - FILL IN THE BLANKS
Correct the worksheet listening to this audio (thanks Cassandra!):

2) Practices: simulation of circuits with crocodile clips

  1. Save the document Practices with Crocodile Clips in your computer (and print it at home!!).
  2. Simulate the circuits in the previous document and answer the questions in your notebook/photocopies ((if you are using your notebook, you have to write down the question too).
  3. If you have to do some practices at home, you can use the program Yenka, instead of Crocodile Clips (you can download Yenka from this website)
(these practices are based on the ones made by Manuel Torres; check his blog for information about these practices and the program Crocodile Clips http://elprofesormanuel.wordpress.com/2011/01/27/crocodile-clips-tecnologia-3%C2%BA-e-s-o/).

3) Some activities

You will be asked to do these activities at home:

4) Symbols

Here you have some information - Electrical Symbols & Electronic Symbols

5) Practice with real circuits

Tools and materials needed

Practices about serial and parallel circuits and polarity


1) Working with LEDs

2) Resistors

This video explains how to get the nominal resistance from the color bands in a resistor

3) Measuring resistance with a multimeter

Here you have a full explanation of how to use the multimeter. Take into account that in 2nd grade we only need to know how to use it to measure resistance.

(Just in case you need it, this is a transcription of what is said in the video: )

3D printing

1) Designing objects with BlocksCAD

We start with 3D printing using blockscad. Follow these instructions:
1. Go to www.blockscad3d.com
3. Click in CREATE NOW and play a little with the options you have on the left margin.
4. Google "tutorial blockscad build a cup" and you will getthe instructions needed to create a mug. Let the teacher know when you finish.
5. Personalize your cup with different colors, shapes, additional objects (more hundles, straws...), your name, etc.
