Gr 7 Up-When England's Jethro Tull developed the seed drill in the early 1700s, other mechanical innovations followed, including the Spinning Jenny for dispersing thread and James Watt's steam engine. Improvements in the textile and iron industries spurred the need for better transportation, so canal waterways were created and railways flourished. Here the video shifts its focus to the United States, whose initial purpose was to supply England with raw materials. Credit is given to the many skilled immigrants who came to America with innovative ideas. By the 1850s science, not mechanics, became paramount. Steel production, electricity, steam ships and the telegraph are some examples of the developments that catapulted America into the age of technology. There are no frills to this video where textbook style information is complemented by illustrations, and the accompanying soft background music changes appropriately with the time period. Some interesting black-and-white film footage is shown, such as the 1903 opening of Henry Ford's first automobile manufacturing plant. The narrator barely takes a breath from segment to segment, making notetaking difficult given the number of names, dates, and inventions presented. This video could be used in both global history and American history curriculums.-Vicki Reutter, Cazenovia High School, NY Copyright 2001 Cahners Business Information.
