There's far too many adults that don't seem to grasp the basic principles of what the discipline of science is.
At the earliest level instead they should be replaced with kids having to come up with experiments to either show something is or is not real based on an existing demonstration.
For instance, I'll make the claim that each different color of Trix has a unique flavor. And that you can test this because when you eat a certain color you always taste the same flavor. Then the kids will have to come up with experiments that show that although that is true, the claim that they are flavored differently is false.
Another example. I'll claim that a tall slender glass holds more liquid then a short and narrow one of equal volume and as evidence I'll show that companies charge more for the tall and slender and people pay more for it willingly.
Essentially you start out with something where the response is "that's true but," and then an experiment is constructed from there.
This approach allows for some important lessons.
1. You don't have to successfully explain the phenomena to demonstrate the claim is false.
2. That science is about skepticism until you're forced to accept something essentially by exhaustion of objections
3. That poorly constructed tests can reproduce a phenomena that you're trying to isolate, etc.
The change is to not make it open ended or have projects or theme fairs. No posterboards or presentations.
Instead it's a form of debate club with interlocutors where groups are trying to fake and fool the others and separate things
When the general public accuses people of putting their "trust in science" I mean, this will kill that. No, science is all about strong methodological distrust - that's one of the basic premises.
