Create a timeline of key developments in agriculture/agriscience. You can either choose to review global changes in agriculture or keep your focus on the United States. Start your timeline after 1800 and make a PowerPoint or other slide-based presentation with one slide for each innovation and include the date of the innovation, where it occurred, and its significance for agriculture/agriscience. There should be a total of 10 slides, and the 19th and 20th centuries should both be well represented. Be sure to include at least one slide from the 21st century as well. Make sure that the slides do not look cluttered or crowded and all information is easy to read.
