Last session was mostly about using a pen and drawing with Scratch. We used "go to mouse-pointer" and Drawing blocks to build a simple drawing program. Then, we learned how to make changes to the colour of our pen. Fairly complex project in the hindsight, and a lot of things to digest but I think you all can have a lot of fun with Scratch pen.
After the lunch break we opened a computer, so you could all see what is inside. We talked about processors, memory and harddrives, and as you could see it is not that complicated as it seems. Of course, to build a computer from scratch, using transistors, would take us a very long time, but using parts you can buy in a shop it is a matter of hours really.
As a bonus project we started a classic Scratch game - car racing, and we almost managed to finish it in time. As a reminder, this is what we were trying to build:
We did not have timers and lap counters, but the basic mechanics was there. I hope that some of you will be able to finish this game and show it off next week.
In the meantime, back-of-the-room group built their scratch stories and a track avoiding game, which was quite complex and involved a lot of good thinking, with animated background and wonderful collisions.
It was quite a good session after all, happy coding....
