1 Industrial Revolution: Inventions and Innovations

2 Essential Question What inventions came about during the Industrial Revolution and how did they change things?

3 Spinning Jenny Invention that made it quicker to produce yarn
Demand for cotton and slaves increase Invented in 1764 by James Hargreaves.


5 Steam Engine It is a heat engine that performs mechanical work using steam as its working fluid. Replaced human energy Perfected by James Watt in the 1760s

6 Steamboat Ships now use steam engines instead of relying on the wind or manpower Transports goods and raw materials quicker and cheaper b/c it can hold more

7 Bessemer Process - Steel
Process that takes iron and produces steel which is stronger and more flexible Get bridges, trains, and eventually skyscrapers Developed in England in the 1850s. Involves blowing compressed air on molten iron (1250 °C) to get out carbon and impurities – creates steel

8 Brooklyn Bridge


10 Electric Light Bulb Can light streets, homes, and most of all, factories Factories can stay open longer – more production

11 Railroads/Locomotives
Shipment of goods/materials – people can receive fresh food/more food in cities Transportation of people Will boost other industries because trains need metals, timber, coal, etc… Started off as large carts attached to a steam engine. One of the most important inventions in the Industrial Revolution for all countries





16 The Factory System Built close to and powered by water at first
Used unskilled labor Bad working conditions/long hours Goal: PROFIT



19 Overall Changes & Effects
Mass production of goods Unskilled labor used Urbanization – growth of cities Movement of people
