Gabbs Checkerspot Butterfly Emerging from Chrysalis
This video features realtime and time lapse footage of a Gabbs Checkerspot Butterfly (Chlosyne gabbii) emerging from its chrysalis and then expanding its wings. This is a great resource to help make real world connections between nature and the classroom. (0:50)
Caterpillar Transforms Into Chrysalis Time Lapse
A Pipevine Swallowtail (Battus philenor hirsuta) caterpillar performs its final molt as it pupates into a chrysalis in time lapse. Actual time was about 90 minutes. This is a great resource to help build background knowledge and to make real world connections between nature and the classroom. (1:00)
Emerging Butterflies Montage--Time Lapse
This collection features 25+ time lapse sequences of Butterflies (and Moths) emerging and expanding their wings. Students will enjoy the real life footage of these amazing insects. What a great way to help build background knowledge and to help make real world connections between nature and the classroom. (2:49)
Arco de Santa MarÃa (Burgos) - en español
El Arco de Santa María, cuyo aspecto actual es del siglo XVI, es una de las antiguas puertas de entrada a la ciudad de Burgos y, sin duda, la más señorial. Por su lado exterior, la puerta de Santa María simula un castillo, con torres, almenas y dos robustos cubos que encuadran el arco. (1:27)

Computer Accuracy
Accuracy of measurement in navigation depends very much on the situation. If a sailor’s target is an island 200 km wide, sailing off center by 10 or 20 km is not a major problem. But, if the island were only 1 km wide, it would be missed if off just the smallest bit. Many of the measurements made while navigating involve angles, and a small error in the angle can translate to a much larger error in position when traveling long distances.
Up, Up and Away! - Airplanes
The airplanes unit begins with a lesson on how airplanes create lift, which involves a discussion of air pressure and how wings use Bernoulli's Principle to change air pressure. Following the lessons on lift, students explore the other three forces acting on airplanes — thrust, weight and drag. Following these lessons, students learn how airplanes are controlled and use paper airplanes to demonstrate these principles. The final lessons addresses societal and technological impacts airplanes hav
Mission to Mars
The Mission to Mars curricular unit introduces students to Mars — the Red Planet. Students discover why scientists are so interested in studying this mysterious planet. Many interesting facts about Mars are revealed, and the history of Martian exploration is reviewed. Students will learn about the development of robotics and how robots are beneficial to science, society and the exploration of space. Details on engineers' involvement in space exploration are presented. Furthermore, students wil
Engineering for the Earth
Young students are introduced to the complex systems of the Earth through numerous lessons on the Earth’s natural resources, processes, weather, climate and landforms. Key earth science topics include rocks, soils and minerals, water and natural resources, weather patterns and climatic regions, wind, erosion, landforms, and the harvesting of fossil fuels — all presented from an engineering point-of-view. (See the Unit Overview section for a list of topics by lesson.) Through many hands-on ac
Learning outcomes By the end of this unit you should be able to: understand the significant issues affecting heritage; engage effectively in debates about heritage issues in Scotland. Except for third party materials and otherwise stated (see terms and conditions), this content is made available under a Author(s): Introduction The case studies in this unit introduce various typologies of heritage and the methods used to study them. The case studies help to draw attention to the fact that the heritage traditions in England, Scotland and Wales are not the same and are enshrined in slightly different legislation. Every study of heritage requires an understanding of the legal context and the traditions and history governing the object of heritage.

"The Power of Masks"with Bill DeLuca
As 1944 running mate to presidential candidate Norman Thomas, vice president hopeful Darlington Hoopes of Pennsylvania delivers a speech about his stand as a member of the Socialist Party. (3:07)
On June 26, 1945, the United Nations Charter was signed. U.S. Secretary of State Edward R. Stettinius discusses his hopes for the new international organization. (0:47)
In a 1943 radio broadcast, Dillon S. Meyer, director of the War Relocation Authority, conveys his disapproval of the Japanese internment camps, which he has been overseeing since they were instituted by President Franklin D. Roosevelt on February 19, 1942. (3:47)
On July 10, 1950, at a meeting of the United Nations Security Council, Ambassador Warren R. Austin reports on North Korea's refusal to retreat from its armed invasion of the Republic of Korea. By the end of the session, the U.N. officially supported sending U.S. forces into Korea. (1:57)
The Martians try communicating with a telephone -- without much success. Yip-yip-yip-yip. Young learners will enjoy this cute video as the martians call the telephone all different kinds of things. It would be a great resource to introduce preschoolers to everyday objects and to help build vocabulary. (2:53)
