Plan and carry out an investigation to determine the effect of materials in the path of a beam of light. Emphasize that light can travel through some materials, can be reflected off some materials, and some materials block light causing shadows. Examples of materials could include clear plastic, wax paper, cardboard, or a mirror.

This is an interactive, first-grade Nearpod lesson tied to SEEd standard 1.3.4. It guides students through information and activities about designing a device that uses sound or light in its structure to communicate over a distance.
This resource is a student-ready, three-dimensional SEEd science lesson you can add to your Nearpod library. Many of the phenomena, text, and images come from UEN OER textbooks, Seedstorylines.org, ck12.org, and pixabay.com. Most videos are from youtube.com or pbslearningmedia.org. Many of the simulations were found at phet.colorado.edu, ck12.org, and pbslearningmedia.org. This lesson is unique to Nebo School District but was built with the help of many amazing ideas from teachers throughout Utah.

Design a device in which the structure the device uses light or sound to solve the problem of communicating over a distance. Define the problem by asking questions and gathering information, convey designs through sketches, drawings, or physical models, and compare and test designs. Examples of devices could include a light source to send signals, paper-cup and-string telephones, or a pattern of drumbeats.

By the beginning of 1865, the Confederacy was dying. Abraham Lincoln, with victory within his grasp, looked forward to a second presidential term and a new challenge – healing the nation he had struggled to reunite. In December 1865, the 13th Amendment abolishing slavery was formally ratified.

The 13th Amendment to the United States Constitution, ratified just months after the end of the American Civil War, abolished enslavement and involuntary servitude—except as a punishment for a crime—in the entire United States. As passed by Congress on January 31, 1865, and ratified by the states on December 6, 1865, the full text of the 13th Amendment reads:

This resource from the National Constitution Center includes an introduction, big questions, recorded class sessions, briefing documents, slide decks, and worksheets about the fourteenth amendment of the United States Constitutuion.

The 14th Amendment to the United States Constitution deals with several aspects of U.S. citizenship and the rights of citizens. Ratified on July 9, 1868, during the post-Civil War era, the 14th, along with the 13th and 15th Amendments, are collectively known as the Reconstruction Amendments. Although the 14th Amendment was intended to protect the rights of formerly enslaved people, it has continued to play a major role in constitutional politics to this day.

The Protohistoric period recorded the stories of developing tribal cultures through oral traditions, written accounts, and cultural artifacts. Pawnee ancestors led the return. Some hunted, and left, others remained and contributed to Ponca, Omaha, and Oto tribes. The Oglala and Brule subgroups of the Teton Dakota were horse nomads. This period saw the first contacts between Europeans and Native Americans. Traders from the East Coast arrived, bringing horses and tools as well as whiskey and conflict.

During the sixteenth century, the native peoples of the Plains would encounter Spanish explorers seeking gold and treasure, and later French and British explorers and traders whose technology changed everyday life forever. Desire to control trade and territory in the Central Plains grew, while the colonies that became the beginnings of America were taking hold on the east coast.

The 15th Amendment, ratified on February 3, 1870, extended the right to vote to Black American men seven years after the emancipation proclamation deemed the enslaved population free. Giving Black men voting rights was yet another way for the federal government to recognize them as full American citizens.

The 16th Amendment to the United States Constitution gives Congress the power to collect a federal income tax from all individuals and businesses without sharing or “apportioning” it among the states or basing the collection on the U.S. Census.

Explorers and trappers followed the rivers at first, but Nebraska's waters were not good for all boats. Paths blazed by Native Americans became the basis for overland routes, including the Oregon Trail. Settlers loaded prairie schooners and headed west over the sea of grass across the Platte Valley. Some perished due to illness or accident. Some sought free land, some sought California gold. Mormons blazed their own trail to escape persecution, wintering near Omaha.

Changes in voting qualifications and participation, the election of Andrew Jackson, and the formation of the Democratic Party"”due largely to the organizational skills of Martin Van Buren"”all contributed to making the election of 1828 and Jackson's presidency a watershed in the evolution of the American political system.

The Kansas-Nebraska Act of 1854 created a territory that stretched all the way north from the southern boundary of present-day Nebraska to include all of the remaining lands of the Louisiana Purchase. Over the years, changes were made that left the territory in roughly the same shape and with roughly the same boundaries as Nebraska has today. Its northern and southern borders were drawn along lines based on a system of longitude and latitude developed in the 18th century. Surveyor set markers to physically mark the imaginary lines on the landscape: sections, townships, and acreages were created.

In this activity, students will analyze a historical map showing percentages of enslaved people by county following the 1860 Census. Students will form an understanding of the distribution of slavery in the southern United States prior to the Civil War.

This video provides an overview of the tensions between of Booker T. Washington and William Monroe Trotter.

In the 1920s, assembly line production and easy credit made it possible for ordinary Americans to purchase many new consumer goods.

This video adapted from the Valdez Museum & Historical Archive, explores what happened during the Great Alaska Earthquake of 1964 through original footage, first-person accounts, and animations illustrating plate tectonics.

In this lesson, students are introduced to the 1973 coup in Chile and then practice using Wikipedia wisely to investigate information about the role of the United States in the coup. Note: A free educator account is required to access these materials.
