"Codificar é divertido"

Desenvolvimento de atividades na plataforma Code.org ou outra, com o objetivo de incentivar os alunos para “a programação e a literacia digital de uma forma divertida e atrativa...”, permitindo também o contacto com os conceitos básicos das Ciências da Computação, pelo menos durante 1 hora.

1. The pixel (a word invented from "picture element") is the basic unit of programmable color on a computer display or in a computer image. ... Up to three bytes of data are allocated for specifying a pixel's color, one byte for each major color component. A true color or 24-bit color system uses all three bytes.

A: In digital imaging, a pixel(or picture element) is the smallest item of information in an image. Pixels are arranged in a 2-dimensional grid, represented using squares. Each pixel is a sample of an original image, where more samples typically provide more-accurate representations of the original.

A pixel is the basic logical unit in digital graphics. Pixels are combined to form a complete image, video, text, or any visible thing on a computer display.

In this activity, legos will represent pixels. Students read the code and fill the squares (pixels) in a 10x8 grid with plastic lego squares and discover the hidden picture. They can either use a picture of a colored-squares-10x8 grid and try to write the code. Either attempts will be uploaded in a padlet in order all school participants to exchange and recreate each others code. Schools can use the examples of the padlet or create new ones, always bearing in mind to use a grid of the same dimensions. At the end all lego creations will be collected and presented in an online art gallery.

Através de um tabuleiro 4 x 4 e de um conjunto de setas/indicações (direita, esquerda, frente) as crianças do grupo irão recontar a história “o gato das botas”. Uma criança será o ‘robô’ que terá de seguir o percurso/recriar a história que as outras crianças do grupo irão programar com as setas.
