We have two items here to help you understand how a bill becomes a law.
First, thanks to the League of Women Voters of Indianapolis for creating this fine explanation of How a Bill Becomes Law in Indiana.
Second, if you are looking for something to help the students in your family understand more about the government here is Ben’s Guide. This website was designed by the U. S Government to inform students, parents and educators about the Federal Government. It’s a great website that includes how a bill becomes a law at the Federal Level along with other important information.
