Please explain how the American election system works in regards to House of reps, senate and President?

I'm from Canada and need to do a project on the American government. Information on these aspects of the election would be very helpful. Thanks!

1. Presidents. The American people do not directly elect the President. It is not by popular vote. It is in the electoral college, by the states. Each states electoral votes is determined by the number of U.S. House of Representatives it has (varies state to state according to population) plus Senators (each state has two) So if a state has 5 House Representatives, plus 2 Senators, it has 7 electoral votes. The states citizens vote for President. Whichever candidate receives most votes, ALL of the states electoral voted goes to him/her. The candidate receiving the most electoral votes, is elected. If the electoral vote is tied, the U.S. House of Representatives elects the President. Presidential term is 4 years, 2 term limit. US House of Representatives. Each state is guaranteed representation in the House according to proportion of population. Every state must have at least one. The greater the population, the more representatives the state has. Each Representative represents a geographic district in the state. ONLY residents in that district can vote for the representative. They serve 2 years, no term limit, and the entire House is up for election in every even numbered year. Senate. The entire state votes for and elects two U.S. Senators by popular vote. Each state has 2 Senators. Senators serve 6 year terms. ,. no term limits. 1/3 of the entire Senate is up for election every two years
