[Digital Design] Use Video-Sensing to Make Scratch Projects

Updated: Mar 22, 2021

Scratch is the most popular block-based platform - of course I got several reasons: accessible, web-based platform, easy to pick up, applicable to various subjects.

I use Scratch a lot as well for my coding lessons. However, when I was looking for some projects online, I'm always fed up with old projects (they're classical, but I want something different!). Until I noticed that we have extensions on Scratch! I have to say that Video Sensing is a cool one that could increase interactions between Scratch projects and players - or we can say improving user experience (UX).

Earlier this year (before we get stuck at home for teaching), my Grade 6 students had a unit about Video-sensing on Scratch. The project I'm gonna introduce in this post is Bubble.

Here is a short clip of video how to play it:


This project could combine with the introduction of the coding concept - function.

Personally, I love to use project-based strategies to introduce coding concepts. In this way, students could have a clearer image about the application of coding concepts; meanwhile, they have opportunities to practice their coding.

Function - is always a difficult one to explain, but in this project, we created a function called "pop" to animate bubbles. Each time, instead of using long, complicated blocks, we can simply call "pop" as much as we need.

I've made an instruction for this project - it worked well in my class. Therefore, I share it in this post. It has 3 pages with the introduction of video-sensing extension.

Please feel free to take it for your lessons.

Last thing, here is the link of the project - Bubble.

Enjoy coding!
