STEM-aktiviteetteja lapsille?

Hello everyone!

Our children (ages 7 and 9) have recently become very enthusiastic about various science and technology (STEM) activities. They are especially interested in math, robotics, and science experiments.

I was wondering if anyone here has any good experiences with events, clubs, or STEM activities at home that are appropriate for that age? It would be nice to hear tips and recommendations, especially ones that allow kids to do and experiment with things in a fun way.

Thank you in advance for your answers!
