Horse carriages, vinyl records, telegraphy, black and white television are all great examples of technology that held tremendous sway decades ago and eventually faded away. Other systems such as railways and telephony too are 'historical' but have advanced into current age too. I think, not being aware of the science behind such yesteryear technologies (or, its history) is not right. I feel, it would be most beneficial to encourage kids to explore old technologies and perhaps, even try simple simulations at home or school.
So, what websites or videos or other sources of information would you reach out to that teaches the basics of say, telegraphy ? Or, signalling in railways ? Etc. etc.

The Plane Finder AR application, developed by a British firm for the Apple iPhone and Google's Android, allows users to point their phone at the sky and see the position, height and speed of nearby aircraft. It also shows the airline, flight number, departure point, destination and even the likely course-the features which could be used to target an aircraft with a surface-to-air missile, or to direct another plane on to a collision course, the 'Daily Mail' reported. The programme, sold for just 1.79 pounds in the online Apple store, has now been labelled an 'aid to terrorists' by security experts and the US Department of Homeland Security is also examining how to protect airliners.
The new application works by intercepting the so-called Automatic Dependent Surveillance-Broadcasts (ADS-B) transmitted by most passenger aircraft to a new satellite tracking system that supplements or, in some countries, replaces radar.

Giving a new dimension to the internet, the Indian research arm of the US-based IT giant IBM has developed a technology that will allow users to talk to the web and create voice sites using mobile phones.
"People will talk to the web and the web will respond. The research technology is analogous to the internet. Unlike personal computers it will work on mobile phones where people can simply create their voice sites," IBM India Research Laboratory Associate Director Manish Gupta said.
