ITN Source, a provider of archival video footage, has published an interesting timeline of the development of technology since 1900. It is absolutely to sit and watch the astronomical changes that have occurred in only 100 years!
The timeline is arranged by decade from 1900 through 2010. I would love to see 2010-2014 – just in that time short time there has been some amazing developments! Each stop on the timeline features a short video about the technological developments of the decade. Although the content is not in-depth it gives a great overview which can serve as discussion starters!
An idea for classroom application could be that Students can create a similar type of timeline by using Timeline JS. Timeline JS allows students to develop timelines that contain videos, images, and text. Click here to be directed through to Timeline JS.
