Here are the activities that each group will be working on today:


If you are new to CoderDojo and new to computer programming this is where you start:

Scratch 1

Paint with Tera

Today you will make a colorful, fun, interactive art piece that responds to the mouse pointer, much like a Paint application on a computer.

You will also learn about an important computer science concept: variables.

Variables are elements that store a value or keep track of things. For example, variables can keep track of time or hold a game’s high score.

Scratch 2

1. My Blocks (a.k.a Functions, Custom Blocks)

Do you fully understand how custom blocks (My Blocks) work and why they are useful? Do you know what parameters are? Do you understand ‘run without screen refresh’? If you are not already an expert on custom blocks, watch this YouTube tutorial and try it out for yourself in Scratch:

2. Car AI Challenge

AI stands for artificial intelligence. In this project you will program a car sprite to give it artificial intelligence to go around a track by itself. You will work on improving the AI code to make the car go around as fast as possible without going off the track

This session is run by Nathalie. An introduction to robotics using mBot robot kits and a block programming language called mBlock which is similar to Scratch.

3D Computer Aided Design with TinkerCAD

Learn how to make 3D models using Tinkercad. Tinkercad is an easy-to-use 3D computer aided design (CAD) tool. You can quickly turn your idea into a CAD model for a 3D printer with Tinkercad.

A collaborative group exploring how computers can interact with the outside world through a range of sensors and controllers. Primarily we’ll be using the Raspberry Pi ( computer in conjunction with Arduinos ( and along the way we’ll learn about Python, C and C++ programming, digital and analogue electronics and about working together.
