Is there a way to describe the connection between 'The Uncertainty Principle" and the "Observer Effect" in layman's terms without notation?

I'm no expert but. The uncertainty principle is I think that measuring one thing I.e. velocity changes its momentum so measuring one thing intrinsically changes another.
The observer effect is that by choosing to observe in a particular way changes how something not only behaves, but must have previously behaved it is about quantum stuff... i.e. I observe light from a distance galaxy it chooses to behave as though for light years previously it's been either a wave or a particle but only choosing due to my act of observation.
