Students learn that newly introduced species can affect the balance of an ecosystem and that the changes can be positive or negative. Students learn that humans introduce species for a variety of reasons including to solve problems.
President John Adams sent this message nominating John Marshall to be Chief Justice of the Supreme Court.
In this lesson, students learn about some of the early explorations of the Northwest Passage, and how the changing sea ice extent has prompted new explorations of this region to transport goods from one region of the Northern Hemisphere to another.
Students learn about nuclear energy generation through a nuclear power plant virtual field trip that includes visiting four websites and watching a short video taken inside a nuclear power plant. They are guided by a handout that provides the URLs and questions to answer from their readings. They conclude with a class discussion to share their findings and reflections. It is recommended that students complete the associated activity, Chernobyl Empathy, before conducting this lesson; doing this assists students in gaining an understanding of how devastating nuclear meltdowns can be, which underscores the importance of careful engineering.
This is a set of two, one-page problems about the sizes of moons in the solar system. Learners will use fractions to compare the sizes and distances of Jupiter's moons. Options are presented so that students may learn about the Juno mission through a NASA press release or by viewing a NASA eClips video [6 min.] about the creation of graphic of the 88 largest objects in our solar system. This activity is part of the Space Math multi-media modules that integrate NASA press releases, NASA archival video, and mathematics problems targeted at specific math standards commonly encountered in middle school.
Pamela shows how objects can inherit and re-use the code of other object types.
Pamela shows how to attach methods to object types, that you can call on any instance of that object.
Pamela explains the first part of object-oriented programming: creating object types and instances of those object types.
Obstacles stand in the way of our wants and needs.
This model of ocean-atmosphere interaction shows how carbon dioxide gas diffuses into water, causing the water to become more acidic. The video demonstration and instruction provide an explanation of the chemistry behind this change and the consequences of ocean acidification. The video also addresses a misconception about how ocean acidification affects shelled organisms.
This module teaches students about ozone’s role in the atmosphere and explores authentic data to compare and contrast conditions that affect ground-level ozone values.
Students learn the definition of entrepreneurship and are introduced to the characteristics of entrepreneurs. Students are asked to apply these characteristics to themselves and people in their own communities by completing a story pyramid and then writing a short story that demonstrates how entrepreneurial activity can contribute to higher standards of living.
Explore how 2D curves can be used to create 1D patterns.
The February 2018 issue of Page One Economics: Focus on Finance focuses on an important milestone in transitioning to adulthood—getting your own place. The article discusses important topics related to renting, including careful preparation and effective planning, a realistic budget, weighing options against important criteria to make the best choice, and understanding a lease.
The student-facing videos are intended to be shown to students as part of the unit while the teacher preparation videos provide information to teachers regarding the set up of laboratory investigations and other features of the instructional materials.
This lesson series is for the Openscapes Champions program, an open data science mentorship program for science teams.
Openscapes Champions is a professional development and leadership opportunity for teams to reimagine data analysis & stewardship as a collaborative effort, develop modern skills that are of immediate value to them, and cultivate collaborative and inclusive research communities. Cohorts are ~7 research teams (~35 total participants including team leads and members) that convene remotely to explore open data science tooling and practices together. This is a remote-by-design program since its launch in 2019.
The Series is written (and always improving) to be used as a reference, to teach, or as self-paced learning.
Openscapes is co-directed by Julia Stewart Lowndes and Erin Robinson. It is operated by the National Center for Ecological Analysis & Synthesis (NCEAS) and was incubated by a Mozilla Fellowship awarded to Lowndes in 2018.
In 1963, Ernesto Miranda was arrested in Arizona and charged with kidnapping, robbery, and rape. When questioned by police, Miranda confessed. He was tried and convicted based on his confession. Miranda appealed his conviction to the U.S. Supreme Court, which ruled in 1966 that statements made by the accused may not be admitted in court without procedural safeguards. Page 31 from the decision describes two of those safeguards—the accused’s right to remain silent and to have an attorney present during questioning. Selected pages are shown.

Featuring Dr. Lindsay Chervinsky, historian at the White House Historical Association and author of The Cabinet: George Washington and the Creation of an American Institution (available April 2020).
Since the Bolshevik Revolution of 1917, Soviet leaders had been claiming that communism and capitalism could never peacefully coexist. Agreements regarding the postwar world were reached at Yalta and Potsdam, but the Soviets wasted no time in violating them. Harry Truman believed that the proper means of responding to an international bully was a credible threat of force.
