If your son was using any of the Turtle languages (Logo) before, he might be interested in NetLogo and NetLogo3D which are very much the grown-up versions of Logo, but just as easy to learn as the more educational versions. Here's an example of what it looks like: https://www.youtube.com/watch?v=7O2fSZ0OwuE https://www.youtube.com/watch?v=7O2fSZ0OwuE It's used in agent based modeling, so there are layers of education possible in learning the language and the many models that come with it. Another thing I totally recommend is a Raspberry Pi Pico (very inexpensive), a Pico Explorer Base, and a handful of electronic components which are easy to find in kit form. There he can learn electronics and the Python programming language at the same time. I have one and I really enjoy jamming on it. https://shop.pimoroni.com/products/pico-explorer-base https://shop.pimoroni.com/products/pico-explorer-base
