Student Exploration: Period of a Pendulum Vocabulary : controlled experiment, mean, pendulum, period Federalism, mode of political organization that unites separate states or other polities within an overarching political system in a way that allows each to maintain its own integrity . Federal systems do this by requiring that basic policies be made and implemented through negotiation in some form, so that all the members can share in making and executing decisions. Prior Knowledge Questio...
