After the bombing of Pearl Harbor, President Franklin D. Roosevelt signed Executive …
After the bombing of Pearl Harbor, President Franklin D. Roosevelt signed Executive Order 9066, which established 10 internment camps for "national security" purposes. Although most internment camps were along the West Coast, others could be found in Wyoming and Colorado, and as far east as Arkansas. One photo shows Japanese American boys in San Francisco shortly before the evacuation order; another shows a woman waiting for the evacuation bus in Hayward; approximately 660 people being evacuated by bus from San Francisco on the first day of the program; and an aerial image of people sitting on their belongings, waiting to be taken to Manzanar. The government-sponsored War Relocation Authority (WRA) hired Dorothea Lange and other photographers to take pictures of the relocation and internment of Japanese Americans. Lange?s photographs, some of which were suppressed by the WRA and only released later, often capture the irony inherent in the situation. Although internees were allowed to take only what they could carry with them to the camps, one Lange photo juxtaposes a bus poster "Such a load off my mind ? Bekins stored my things" next to a pile of internees' belongings. Another striking Lange image shows a Japanese American-owned corner store with a large "I am an American" banner hanging beneath a "Sold" sign. Another photograph of an engine's distributor, removed from a car owned by an internee, showed that people were truly prisoners at the camp, unable to drive their own cars away. Several paintings by interned Japanese American artists Henry Sugimoto and Hisako Hibi reflect their emotional experiences and give viewers a sense of what life was like for them. The paintings express the pain, suffering, and anger of those subjected to internment. Over 100,000 Japanese American men, women, and children were relocated and detained at these camps. Photographs here show people of all ages, including a grandfather and grandchild, and young children. This internment is now recognized as a violation of their human and civil rights. In 1980, the US government officially apologized and reparations were paid to survivors.

This is a JiTT exercise in which students apply introductory-level macroeconomic analysis to the question of how large the stimulus package put forward to Congress in early 2009 needed to be to close the recessionary gap facing the U.S. economy at that time. In particular, this exercise asks students to bring together the concepts of potential and actual GDP, recessionary gaps, fiscal policy, spending and taxing multipliers, and effects of changes in aggregate spending on employment and output.

The goal of this exercise is to determine whether the realities of women's lives in the 1950s match the idealized view of that time period we have today. Crosstabulation and comparison of means will be used.

Giant clams are no myth. In New England, people love clam chowder, but in the Pacific, some of the clams are as big as a suitcase! In this video filmed in Micronesia, Jonathan goes in search of Giant Clams. These clams are so big that people used to think they caught people...and it almost looks like they could. It turns out that the real problem is that too many people are eating the clams. Please see the accompanying lesson plan for educational objectives, discussion points and classroom activities.

This activity shows how our experience of the Sun changes with time and location. The sun dagger at Chaco Canyon is thought by many to be a sort of ancient timekeeping device. By creating a place where the movement of the Sun could be tracked day after day, Chacoans could mark the passage of time and gain an idea of when seasons were changing. If the Chacoans could use a particular location and the Sun to tell them about time, can we use time and the Sun to tell us about our location? In this easy experiment, you'll see how the position of the Sun in the sky is related to where we are on the earth.

This is a lesson about geologic history. Learners will work together to create models of volcanic lava flows and analyze the layers that form on a planet's surface. They will sequence lava flows produced by multiple eruptions. Students will be asked to observe where the flows travel, make a model, and interpret the stratigraphy. Students will use their volcanic layering model to demonstrate the relative dating and geologic mapping principles to later be applied to satellite imagery. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes and vocabulary.
