I’m actually with @sheeldz on this too because there is a very good cognitive reason for trying to explain the real science even though the small child wont understand consciously understand or process it
so, here’s a scientifically controlled lab experiment;
a group of people with no familiarity of the Chinese alphabet are shown 5 Chinese letters
two weeks later the group is split in to 2, a) & b)
both groups are shown the same image of 40 chinese word & letter symbols including the original 5 disperse randomly
group a) is asked which are the 5 symbols the saw two weeks ago. The results are always a chance - below chance outcome. Usually below chance.
group b) is asked which are your 5 favourite symbols. There is a stronger than 80% chance that each respondent in group b names the precise 5 symbols that they saw 2 weeks ago as their favourite
In other words, without being able to consciously or rationally process information we are always predisposed to being more positive & open to that information when it is repeated
thus, when explaining scientific principles to small children who obviously don’t understand them you are actually training them at an unconscious level to be positive to those concepts & ideas in the future & thus helping them to learn them when they are rationally able to process them
you are also introducing them to new language & sounds which is ALWAYS a good thing for mental development
good eh?
