The influence of the media is increased by the fact that campaigns today have become more focused on the individual than on the party. In order to win primaries, individual candidates seek media attention to gain attention from voters. As a result, do voters hold political power, or has the media simply replaced political parties as the primary force behind candidate selection?

Despite promises made by presidential candidates, the President has no direct power to pass any legislation. This very important power lies solely with the House of Representatives and the Senate.

The Constitution specifically grants Congress its most important power — the authority to make laws. A bill, or proposed law, only becomes a law after both the House of Representatives and the Senate have approved it in the same form. The two houses share other powers, many of which are listed in Article I, Section 8. These include the power to declare war, coin money, raise an army and navy, regulate commerce, establish rules of immigration and naturalization, and establish the federal courts and their jurisdictions.

The federal courts' most important power is that of judicial review, the authority to interpret the Constitution. When federal judges rule that laws or government actions violate the spirit of the Constitution, they profoundly shape public policy. For example, federal judges have declared over 100 federal laws unconstitutional.

The states now faced serious and complicated questions about how to make their rules. What did it mean to replace royal authority with institutions based on popular rule? How was "popular sovereignty" (the idea that the people were the highest authority) to be institutionalized in the new state governments? For that matter, who were "the people"?

The central failure of the Congress was related to its limited fiscal power. Because it could not impose taxes on the states, the national government's authority and effectiveness was severely limited. Given this major encumbrance, the accomplishments of the Congress were quite impressive. First of all, it raised the Continental Army, kept it in the field, and managed to finance the war effort.

The 1780s has often been termed the "critical period" for the new nation. The dangers posed by economic crisis and the disillusionment that came with the collapse of Revolutionary expectations for dramatically improved conditions combined to make the decade a period of discontent, reconsideration, and, in the end, a dramatic new proposal for redirecting the nation. Just as the Revolution had been born of diverse and sometimes conflicting perspectives, even among the Patriots, so too, ideas about the future of the United States in the 1780s were often cast in dramatic opposition to one another.

Washington's towering stature and legacy might misleadingly suggest that the early years of the new nation were times of great confidence and self-congratulation. In fact, just the opposite was nearly the case. Americans knew that the historical record of the long-term success of republican governments was exceedingly poor. Previous examples and classical political theory suggested that republics almost all suffered the fate of collapsing into anarchy and then being taken over by a power-seizing tyrant.

Rather than continue to use the exigencies of war to build his own popularity and to justify the need for strong federal authority, Adams opened negotiations with France when the opportunity arose to work toward peace. Reconciling with France during the critical campaign of 1800 enraged many Federalists, including Adams' own secretary of state who repeatedly refused to send peace commissioners to France.

The Gilded Age will be remembered for the accomplishments of thousands of American thinkers, inventors, entrepreneurs, writers, and promoters of social justice. Few politicians had an impact on the tremendous change transforming America. The Presidency was at an all-time low in power and influence, and the Congress was rife with corruption. State and city leaders shared in the graft, and the public was kept largely unaware. Much like in the colonial days, Americans were not taking their orders from the top; rather, they were building a new society from its foundation.

Use aluminum foil, salt water, and activated charcoal to construct a simple battery strong enough to power a small motor or light.

An 8th grade social studies unit, co-taught with the school librarian, about the impact of American Public PolicyThis lesson plan is meant to serve as one lesson in a wider 8th grade social studies unit on the impact of American public policy.  The lesson focuses on the impact of the public policy of slavery.  The wider unit would also include whole-class study of the impact of Native American Removal and Indian Schools.  At the end of the unit, students would investigate a contemporary issue of American public policy and develop and put into practice a plan to draw attention to that public policy issue.   

Look inside a resistor to see how it works. Increase the battery voltage to make more electrons flow though the resistor. Increase the resistance to block the flow of electrons. Watch the current and resistor temperature change.

Students are introduced to several key concepts of electronic circuits. They learn about some of the physics behind circuits, the key components in a circuit and their pervasiveness in our homes and everyday lives. Students learn about Ohm's Law and how it is used to analyze circuits.

Students learn about gear ratios and power by operating toy mechanical cranes of differing gear ratios. They attempt to pick up objects with various masses to witness how much power must be applied to the system to oppose the force of gravity. They learn about the concept of gear ratio and practice calculating gear ratios on worksheets, discovering that smaller gear ratios are best for picking objects up quickly, and larger gear ratios make it easier to lift heavy objects.

Students gain an understanding of the factors that affect wind turbine operation. Following the steps of the engineering design process, engineering teams use simple materials (cardboard and wooden dowels) to build and test their own turbine blade prototypes with the objective of maximizing electrical power output for a hypothetical situation—helping scientists power their electrical devices while doing research on a remote island. Teams explore how blade size, shape, weight and rotation interact to achieve maximal performance, and relate the power generated to energy consumed on a scale that is relevant to them in daily life. A PowerPoint® presentation, worksheet and post-activity test are provided.

Demos and activities in this lesson are intended to illustrate the basic concepts of energy science -- work, force, energy, power etc. and the relationships among them. The "lecture" portion of the lesson includes many demonstrations to keep students engaged, yet has high expectations for the students to perform energy related calculations and convert units as required. A homework assignment and quiz are used to reinforce and assess these basic engineering science concepts.

Play with a bar magnet and coils to learn about Faraday's law. Move a bar magnet near one or two coils to make a light bulb glow. View the magnetic field lines. A meter shows the direction and magnitude of the current. View the magnetic field lines or use a meter to show the direction and magnitude of the current. You can also play with electromagnets, generators and transformers!
