This art history video dicussion examines Georgia O'Keeffe's "The Lawrence Tree", oil on canvas, 31 x 40 inches, 1929 (Wadsworth Atheneum, Hartford). Painted in the summer of 1929 while visiting D.H. Lawrence at his Kiowa Ranch during O'Keeffe's first trip to New Mexico, the tree stands in front of the house.
This video segment adapted from Shedding Light on Science illustrates how light changes speed, and thus direction, in a process known as refraction.
This interactive tool allows students to gather data using My NASA Data microsets to investigate how differential heating of Earth results in circulation patterns in the oceans and the atmosphere that globally distribute the heat. They examine the relationship between the rotation of Earth and the circular motions of ocean currents and air. Students also make predictions based on the data to concerns about global climate change. They begin by examining the temperature of oceans surface currents and ocean surface winds. These currents, driven by the wind, mark the movement of surface heating as monitored by satellites. Students explore the link between 1) ocean temperatures and currents, 2) uneven heating and rotation of Earth, 3) resulting climate and weather patterns, and 4) projected impacts of climate change (global warming). Using the Live Access Server, students can select data sets for various elements for different regions of the globe, at different times of the year, and for multiple years. The information is provided in maps or graphs which can be saved for future reference. Some of the data sets accessed for this lesson include Sea Surface Temperature, Cloud Coverage, and Sea Level Height for this lesson. The lesson provides directions for accessing the data as well as questions to guide discussion and learning. The estimated time for completing the activity is 50 minutes. Inclusion of the Extension activities could broaden the scope of the lesson to several days in length. Links to informative maps and text such as the deep ocean conveyor belt, upwelling, and coastal fog as needed to answer questions in the extension activities are included.
This video adapted from KTOO explores the impact of oil contamination on the herring population of Prince William Sound, Alaska, in 1999, 10 years after the Exxon Valdez oil spill.
This short video and interactive assessment activity is designed to teach fourth graders about one-step conversions between multiples of 10.
This short video and interactive assessment activity is designed to teach third graders about one-step conversions involving multiples of ten.
This short video and interactive assessment activity is designed to teach fourth graders about one-step subtraction conversions with compound units (metric units) - word problems.
In this video segment adapted from the Yukon River Panel, visit fishing communities along the Yukon River and see how Alaska Native peoples exercise stewardship of salmon to ensure that it remains a central food source and cultural touchstone.
This is a supplementary video for the Commonwealth of Learning Open Textbook Manual. It shows how to create Lessons in OER Commons. The OER Commons Lesson Builder allows instructors to create resources that are viewable by students as lessons, and by teachers as lesson plans with supplemental instructional resources.
In this video lesson, students will learn about linear programming (LP) and will solve an LP problem using the graphical method. Its focus is on the famous "Stigler's diet" problem posed by the 1982 Nobel Laureate in economics, George Stigler. Based on his problem, students will formulate their own diet problem and solve it using the graphical method. The prerequisites to this lesson are basic algebra and geometry. The materials needed for the in-class activities include graphing paper and pencil. This lesson can be completed in one class of approximately one hour. If the teacher would like to cover the simplex algorithm by George Dantzig as an alternative solution method, an additional whole class period is suggested.
This video, adapted from material provided by the ECHO partners, illustrates how Native people preserve history and tradition through art, music, and dance.
