In the second part of the activity, students are asked to learn more about the historic figures mentioned by doing read
Earth's history in 4.56 meters: constructing a timeline with calculator tape
In this short activity, students make a timeline of Earth's history using calculator tape. The tape is 4.56 meters long, so that one billion years is equal to one meter. This exercise is designed to introduce students to the scale of Earth's history and help them gain a familiarity with some major events. It also teaches about scaling, the metric system, as well as the concepts of large numbers and deep time. The activity may be used in an introductory geoscience course. Learning goals, context
Driving Through Geologic Time - An analogy
This activity uses an analogy to illustrate the scale of geologic time and our limited view of the Earth's history. It relates the history of the Earth to a drive across the country. The drive is 4560 km (rough distance between Washington D.C. and Seattle), with 1 km equaling one million years of Earth's history. This analogy is used by the author as a springboard to talk about the limits of our personal perceptions and experiences when making conclusions. Learning goals, context for use, teachi
Lakota Winter Counts
offers the world's largest database of Lakota winter counts -- pictures drawn on cloth or buffalo hide to remember each year's key events (1701 to 1905). Ten Lakota bands' winter counts are shown side by side on a timeline. Compare how the bands depicted a particular year. Search for an image. Watch interviews with Lakota. Learn about the culture of this Sioux tribe of the northern plains that followed buffalo herds for food. A teachers guide is included.
We'd Like to Thank You, Herbert Hoover
Since the advent of book musicals such as "Show Boat" and "Oklahoma!", many Broadway shows have touched upon relevant social and historical issues. In this lesson, students will investigate how Broadway musicals can reflect the times in which they were created. Students will examine video clips and Web sites related to relevant productions, study song lyrics, and compare and contrast actual history with Broadway history. By becoming "historical detectives," they will determine how accurately Bro
The Cutting Edge - Exploring How Editing Affects an Author's Work
In this lesson, students examine the writing of short-story author Raymond Carver as well as their own writing to explore how editing can affect the text, content and context of an author's work.
Teach Your Parents Well - Educating Adults to Help Bridge the Digital Divide
