This lesson unit is intended to help teahcers assess how well students solve problems involving measurement, and in particular, to identify and help students who have the following difficulties; computing measurements using formulas; decomposing compound shapes into simpler ones; using right triangles and their properties to solve real-world problems.

Explore how a capacitor works! Change the size of the plates and add a dielectric to see how it affects capacitance. Change the voltage and see charges built up on the plates. Shows the electric field in the capacitor. Measure voltage and electric field.

By studying paintings from the Cave of Lascaux (France) and the Blombos Cave (South Africa), students will discover that pictures can be a way of communicating beliefs and ideas and can give us clues today about what life was like long ago.

This lesson is part of a series called “Changing Demographics, Changing Identity, Changing Attitudes” The series focuses on how the American identity has and will continue to change as we move toward a plurality nation, how the nation responds to that evolving identity, how changing demographics relate to issues of equality, and what we can do to promote respect for all people living in the United States.

In this lesson, students consider actions we can take to promote respect and ensure equality for all people living in the United States.

Move point charges around on the playing field and then view the electric field, voltages, equipotential lines, and more. It's colorful, it's dynamic, it's free.

Using the landmark feminist short story "The Yellow Wall-paper," students will employ close reading concepts to analyze setting, narrative style, symbol, and characterization.

Charlotte Perkins Gilman's story "The Yellow Wall-paper" was written during atime of change. This lesson plan, the first part of a two-part lesson, helps to set the historical, social, cultural, and economic context of Gilman's story.

This lesson provides a Common Core application for high school students for Chinua Achebe's novel Things Fall Apart. Students will undertake close reading of passages in Things Fall Apart to evaluate the impact of Achebe's literary techniques, the cultural significance of the work, and how this international text serves as a lens to discover the experiences of others.

Nigerian born Chinua Achebe is one of the world's most well-known and influential contemporary writers. His first novel, Things Fall Apart (1958), is an early narrative about the European colonization of Africa told from the point of view of the colonized people.

Students learn the linguistic strategies Achebe uses to convey the Igbo and British missionary cultures presented in the novel and how the text combines European linguistic and literary forms with African oral traditions.

The traditional religions of Great Britain's North American colonies had difficulty maintaining their holds over the growing population. This did not, however, result in a wholesale decline in religiosity among Americans.  In fact, the most significant religious development of 18th century America took place along the frontier, in the form of the Great Awakening. This curriculum unit will, through the use of primary documents, introduce students to the First Great Awakening, as well as to the ways in which religious-based arguments were used both in support of and against the American Revolution.

This lesson provides students with tools to analyze primary source newspaper articles about the Great War (1914"“1917) in order to understand public opinion regarding the U.S. entry into the war from multiple perspectives.

This lesson brings together digital mapping and the Chronicling America newspaper database as part of an inquiry into how and where the women's suffrage movement took place in the United States. Primary source newspaper articles published between 1911-1920 and maps from 1918-1920 are used to prompt student research into how women organized, the type of elections that women could participate in, and the extent to which the 19th Amendment transformed voting rights in the U.S.

Created through a partnership between the National Endowment for the Humanities and the Library of Congress, Chronicling America offers visitors the ability to search and view newspaper pages from 1690-1963 and to find information about American newspapers published between 1690"“present using the National Digital Newspaper Program.

This new version of the CCK adds capacitors, inductors and AC voltage sources to your toolbox! Now you can graph the current and voltage as a function of time.

Build circuits with capacitors, inductors, resistors and AC or DC voltage sources, and inspect them using lab instruments such as voltmeters and ammeters.

An electronics kit in your computer! Build circuits with resistors, light bulbs, batteries, and switches. Take measurements with the realistic ammeter and voltmeter. View the circuit as a schematic diagram, or switch to a life-like view.
