Explain checks and balances. explain the preamble of the constitution. predict whether our amendments will stay the same or change. explain why think they will or won’t.

Checks and balances is so that the branches of government don't over power each other,  the preamble states that we have the ability to speak our minds and that we are treated fairly and equally and that no Americans rights are not taken away from them and i don't think that our amendments will not change because they haven't changed in a long time

They made a checks and balance system to equal power within the branches. the "check" meant that one branch would watch one branch and "balance" them if they were too powerful. if you want more info on this, i would just google checks and balance system.
