African American History to 1950: Examine African American history in the contexts of United States, North Carolina and world history. Assignments draw from a wealth of classroom-oriented primary sources, including slave testimonies, photographs, oral histories, and more.; Take this course: Begins January 6.

English-only movement: Movement to make English the only language used in U.S. public education. English-only proponents argue that bilingual education and bilingualism threaten a sense of national identity and create divisions along ethnic lines.

Earthquakes: Causes and effects: This is a lesson plan designed to stimulate student interest in the forces of nature. The lessons culminate in a hands-on learning experience about earthquakes.; Format: lesson plan (grade 6 Science); By Tom Weakland.

Evaluate forces: Earthquakes: In CareerStart lessons: Grade six, page 3.3; This lesson for grade six will help students to gain an understanding of geological processes including plate tectonics, faulting, and earthquakes. Students will explore careers related to earthquake analysis, measurement, and disaster management.; Format: lesson plan (grade 6 Science); By April Galloway and Christine Scott.

Getting to know spiders: This lesson is useful for helping students understand the differences between spiders and insects. They will also learn about a spider's particular body parts. Live spiders will be observed over the course of a few days to see how sound, light, and movement affect the spiders.; Format: lesson plan (grade 2 Science); By Bree Welmaker.

Atomic spectra and the Bohr model: Students view continuous spectra from incandescent and fluorescent lights and line spectra of selected elements. Students relate energy to frequency of light seen in the spectra. The presence of only certain lines in atomic spectra is related to Bohr's model of the atom. In a second experiment, students determine electron energies in the hydrogen atom.; Format: lesson plan (grade 9–12 Science); By Lisa Bacon.

Round and Round It Goes; Water, Where It Stops Nobody Knows: The hydrologic cycle is the process, powered by the sun, which identifies the constant, endless movement of water from the atmosphere to the earth to the ground water, to the rivers to the oceans and back into the atmosphere. This experimental lab lesson will show the process of the hydrologic cycle as it relates to the earth's atmosphere by showing three different scenarios,the first scenario (the control), container A, shows the hydrologic cycle with no contaminates. The second scenario, container B, shows the hydrologic cycle with the earth's soil contaminated. The third scenario, container C, demonstrates the hydologic cycle with the air polluted. These three situations will give the student an idea of how the atmosphere and the growth of plant life are affected by different contaminants in the earth.This lesson will, in fact, investigate the hydrologic cycle experimentally.; Format: lesson plan (grade 9–12 Science); By Mark Clinkscales and Carrie Palmer.
