Students will learn how the Preamble to the U.S. Constitution was shaped by historical events and how it reflected the fundamental values and principles of a newly independent nation.
The presidential election of 1824 represents a watershed in American politics. The collapse of the Federalist Party and the illness of the "official candidate" of the Democratic-Republicans led to a slate of candidates who were all Democratic-Republicans. This led to the end of the Congressional Caucus system for nominating candidates, and eventually, the development of a new two-party system in the United States. In this unit, students will read an account of the election from the Journal of the House of Representatives, analyze archival campaign materials, and use an interactive online activity to develop a better understanding of the election of 1824 and its significance.
Through these lessons, students learn to identify and describe the various roles and responsibilities of the President of the United States and their own roles as citizens of a democracy.
In order to become informed participants in a democracy, students must learn about the women and men who make decisions concerning their lives, their country, and the world. The President of the United States is one such leader. As a nation, we place no greater responsibility on any one individual than we do on the president. Through these lessons, students learn about the roles and responsibilities of the president and their own roles as citizens of a democracy.
Blast a Buick out of a cannon! Learn about projectile motion by firing various objects. Set the angle, initial speed, and mass. Add air resistance. Make a game out of this simulation by trying to hit a target.

This lesson unit is intended to help teachers assess how well students are able to produce and evaluate geometrical proofs. In particular, this unit is intended to help you identify and assist students who have difficulties in: interpreting diagrams; identifying mathematical knowledge relevant to an argument; linking visual and algebraic representations; and producing and evaluating mathematical arguments.
This lesson unit is intended to help teachers assess whether students are able to: identify when two quantities vary in direct proportion to each other; distinguish between direct proportion and other functional relationships; and solve proportionality problems using efficient methods.
This lesson unit is intended to help teachers assess how well students are able to: use the area of right triangles to deduce the areas of other shapes; use dissection methods for finding areas; organize an investigation systematically and collect data; deduce a generalizable method for finding lengths and areas (The Pythagorean Theorem.)
Explore the properties of quantum "particles" bound in potential wells. See how the wave functions and probability densities that describe them evolve (or don't evolve) over time.
Watch quantum "particles" tunnel through barriers. Explore the properties of the wave functions that describe these particles.
When do photons, electrons, and atoms behave like particles and when do they behave like waves? Watch waves spread out and interfere as they pass through a double slit, then get detected on a screen as tiny dots. Use quantum detectors to explore how measurements change the waves and the patterns they produce on the screen.
Racial profiling occurs when law enforcement agents impermissibly use race, religion, ethnicity or national origin in deciding who to investigate. This lesson focuses on racial profiling. Students learn what the term means, discuss why it matters, conduct research and present their insights.
The electric field lines from a point charge evolve in time as the charge moves. Watch radiation propagate outward at the speed of light as you wiggle the charge. Stop a moving charge to see bremsstrahlung (braking) radiation. Explore the radiation patterns as the charge moves with sinusoidal, circular, or linear motion. You can move the charge any way you like, as long as you don���������t exceed the speed of light.
Broadcast radio waves from KPhET. Wiggle the transmitter electron manually or have it oscillate automatically. Display the field as a curve or vectors. The strip chart shows the electron positions at the transmitter and at the receiver.

Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating to work. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.

Lorraine Hansberry's A Raisin in the Sun provides a compelling and honest look into one family's aspirations to move to another Chicago neighborhood and the thunderous crash of a reality that raises questions about for whom the "American Dream" is accessible.
Explore forces, energy and work as you push household objects up and down a ramp. Lower and raise the ramp to see how the angle of inclination affects the parallel forces acting on the file cabinet. Graphs show forces, energy and work.
