What you said isn’t unreasonable but so generic it hardly says “must buy chemistry set”.
“Previously done research” like “these things taste good together” and “add this to cleaner to get a nice smell.” Sounds like riffing on the world right around them. You’re not going to get functionally fixed on when and where to use generic language like “previously done research” are you?
The rigor can come in when the work demands it. Kid’s chemistry sets are not saving lives or unlocking new truths. The industrial pipeline to produce them hardly seems worth it.
You do you. Personally, I prefer the path of least resistance for myself; buying less, dealing with less mess, and using the immediate environment to explore the same language and ideas. Of course it means having an imagination. Something adults often lack, seeing the path of least resistance as living in their memory, behaving literally in lock step with it.
To these people as well; cooking is chemistry. Making household cleaners is chemistry.
To do chemistry with kids all one needs is a grocery store, an herb shoppe, and the right explanations for what’s going on.
But instead there’s bunch of waxing poetic about how the world has changed. It’s rather pathetic to think science should come neatly labeled in a box. The lack of individual creativity and imagination in our culture is stunning.
“This is all we sell, take it or leave it.” is not a confirmation of what the buyer wants.
Supply side reviewing past sale’s history and deciding to sell some twist on a past thing that sold creates an “take it or leave it, because we decided this was most likely to sell” market dictated by supply sides review of the past.
