The best courses I took in college were based around the idea that the class was working towards a difficult to find correct answer, but that any statement or question that got you closer to that answer was a worthy contribution. I found that most of my classmates were willing to go out on a limb and propose solutions (even if they weren't sure) because the response was usually "let's explore if that answer is true, and if not, that exploration could lead us somewhere anyway." A thought that was not immediately a correct answer is still worth contributing because it is a step towards truth as long as your group is willing to commit to working through and incrementing on everyone's ideas.
we have the crunchlabs projects all over our house lol. Arduino is a good idea. His science fair project last year was a makey makey that uses bananas as video game controllers

try an arduino starter kit for the kids, good hands on intro to programming / engineering.
if you want something more polished check out mark rober's: https://www.crunchlabs.com/
