I'm a Physics specialist, but teach all 3 sciences. Hardly anything we teach cannot be converted into a life lesson, and, in fact, I am using an awful lot of science every day without thinking about it. But I also point it out to the kids.
So when you ask "what have you learned at school today" you might get "pressure", but while that may have been the title of my lesson, I will have talked about the dangers of closed gas containers, the use of tyre pumps and why heels in sand may be a bad idea - things you regularly see people get wrong in the countless fail compilations the kids watch on tik tok.
We might do a few lessons on electricity, in which children will learn the basics of circuits, which my father used to wire a doll house when I was young and which I use to this day to sort basic things like finding a circuit fault in the house (is it the bulb, a loose wire or fuse), to attach a British plug to an appliance I brought over from my home country or to change a broken (or just ugly) light switch.
I teach kids about the relationship between surface area or air movement and the rate of evaporation, which, I point out to them, I use to my advantage when drying clothes outside. The number of kids who don't know that clothes dry perfectly fine even in temperatures like the ones we have now is astonishing.
But all of those things cannot be taught properly without a basic understanding of particles, or, in the case of electricity, why materials conduct electricity.
We also spend a lot of time talking about different types of power stations and the differences between renewable and non-renewable energies, and, in that, why the world is changing to electric cars, reducing plastic pollution or why electricity has become so expensive. We even cost electicity, and yes, we teach how an energy bill works.
Kids learn a lot of life lessons in school, but too many of them don't take an awful lot of it in and forget they've ever been taught this stuff.
Besides all these hidden little life lessons, which are rarely appreciated, don't forget that what your kids are getting from school is a formal qualification. And when you look back at your own formal qualifications, you will see that each and every one of them required more than just a bit of common sense.
