Senate: One part of Congress, made up of two senators from each state regardless its size or population. It's like a class where every student gets equal say no matter how tall they are or how many friends they have.
House of Representatives: The other part of Congress, representatives are based on each state’s population. Picture this as if you're playing a game where teams get more players based on how many people they have supporting them.
Bicameral Legislature: A lawmaking body made up two chambers or parts - in US context, these are Senate and House Of Representatives. Imagine this as having two team captains instead one; both need to agree before any decision is final.
