Middle and High School educators across Lebanon County, Pennsylvania developed lesson plans to integrate the Pennsylvania Career Education and Work Standards with the content they teach. This work was made possible through a partnership between the South Central PA Workforce Investment Board (SCPa Works) and Lancaster-Lebanon Intermediate Unit 13 (IU13) and was funded by a Teacher in the Workplace Grant Award from the Pennsylvania Department of Labor and Industry. This lesson plan was developed by one of the talented educators who participated in this project during the 2019-2020 school year.

In this lesson students will read to uncover hidden truths about the many contributions of enslaved Africans to the development of the United States. They will express their understanding by writing a text-based claim supported by evidence to show how African Americans paved the way for other marginalized communities to fight oppression, so the principles of American democracy apply to all people in America.

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.

In this lesson, students use a guided reading to look at a report on the status of education in North Carolina in 1869, and discuss the reasons given then for why the Governor and Legislature should support educating North Carolina's children. They are provided an opportunity to compare and contrast the 1869 document against their own ideas about the civic duty to attend school through age sixteen, and its relative value to the state and the country.

Author: Daniel Shogan, Danville Museum of Fine Arts and History Students will learn about the 1883 Massacre in Danville, Virginia as an example of racist mob violence against African Americans. Within the context of the massacre, they will be shown primary documents from the event. These documents will provide the students with not only a lens into the Danville of the nineteenth century, but also provide them with an opportunity to think critically about the biases present in some of the documents. After careful discussion of the events and outcomes of the massacre, the students will be given vocabulary worksheets that help to define and underline the most important elements of the narrative.

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

After the Philippine-American War ended in 1902, Americans became fascinated by the natives of the newly acquired territory, which led to the development of anthropological exhibits showcasing what “primitive” life was like in the Philippines. During this time period, anthropologists adopted an evolutionary perspective rooted in white superiority. One of the exhibits featured the Igorot people, who anthropologist Albert Jenks believed were the most uncivilized tribe in the Philippines. These exhibits/human zoos sparked the creation of negative stereotypes of both the Igorot people and the Filipino community. Students will view the video segment from Asian Americans and engage in activities and discussions to explore the power of perception and its impact on shaping the identities of Asian Americans. Students will also examine the U.S. politics and scientific theories that shaped the perception of Americans and sought to justify U.S. colonization in the Pacific and the mistreatment of the Filipino community.

Overview
Thousands of high school students walked out of classes in East Los Angeles in 1968 to protest unequal treatment of Mexican Americans in the public education system. Among the students' concerns were classes that omitted Hispanic history, a lack of bilingual teachers and a system that steered Chicano students to vocational training rather than college-prep classes.

Sparked off by the acquittal of four officers in the Rodney King police brutality case, the 1992 Los Angeles Civil Unrest took place over several days and led to rioting and destruction of the city. The unrest represented a boiling point of underlying issues including systemic racism, police brutality, failure of the criminal justice system, economic disparities between communities of color, and racial tensions. The perceived racial tensions between Korean and Black Americans, further complicated by the shooting of Latasha Harlins by a Korean storeowner, led to some targeting of Korean American neighborhoods/businesses for violence and looting. Students will explore the history, conditions, and tensions that led to the 1992 civil unrest in L.A.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"The Materials Research Society is proud to announce the 2020 MRS Communications Lecture honorees, Drs. Chun-Teh Chen and Grace Gu from the University of California, Berkeley. The honor recognizes excellence in the field of materials research through work published in MRS Communications. Drs. Chen and Gu are recognized this year for their prospective paper on how researchers are harnessing artificial intelligence to accelerate the design and discovery of composite materials. Their work is featured in volume nine, issue two of MRS Communications. Composites are combinations of two or more base materials, whose collective properties exceed those possessed by either material alone. Composites are widely used as structural materials in the automotive and aerospace industries and can also be easily found in nature. Limitations in manufacturing methods have generally restricted the architecture these materials take on in real-world applications. Most commonly, they’re processed into multilayer sheets..."

This online course is designed to help anyone teach – and learn – with a 21st century approach to knowledge and teaching. Lesson 1 of the course shares important evidence we now have about the working of the brain, that is meaningful for all subjects and ages – and lives. We then move to thinking together about the data filled world in which we live, to prepare students for their future in a world of data.
The aim of a data science approach is not to add new standards or content to your teaching, it is about interacting with your content in a data science way – that is fun, interesting and creative. In the course you will experience lessons that you can take and use with your students, and you will see lots of classroom and lesson examples. Whether you are a kindergarten teacher, a high school history or maths teacher, an administrator or parent, or someone just curious about data science, there will be ideas for you.

This activity is designed for a primary classroom (outdoors & indoors) investigation where students collect and investigate soil samples and describe the soils, looking for similarities and differences.
