The secret messages of Viking runestones

The Vikings are usually associated with longships, exploration, battles and raids, but there is another side of their culture that is perhaps less familiar: the stories they left behind in stone. This short TED-Ed lesson, presented by historian Jesse Byock, takes us into the world of Viking runestones and the mysterious messages written on them in Old Norse using runic letters.

The video is a fascinating introduction to the Vikings through something they actually left behind. Instead of focusing only on the usual images of warriors and ships, it looks at the fragments of stone, bone and other materials that have helped historians understand Viking society. Runestones become a kind of historical evidence, giving us clues about the people who created them, what they believed, who they wanted to remember and even how they wanted to be remembered.

The animation also introduces students to the idea that writing has not always looked the way it does today. The runic alphabet, or futhark, opens up an interesting door into language and communication. Students can see how a written message can survive for centuries and become a source of information about a society that disappeared long ago. At the same time, it is a good reminder that historians often have to piece together the past from incomplete evidence rather than simply finding a book that tells them exactly what happened.

One of the things that makes this resource work particularly well in the classroom is its combination of history, language and visual storytelling. The animation is short and accessible, making it easy to use as an introduction to a unit on the Vikings, the Middle Ages or the history of writing. It could also work well in an English lesson, especially with students who enjoy history, fantasy or archaeology. The vocabulary provides plenty of opportunities to work with words connected with writing, symbols, exploration, ancient cultures and historical evidence.

There is also a nice opportunity for students to go beyond simply watching the video. After viewing it, they could investigate a Viking runestone, try to identify some runic symbols, research what inscriptions tell us about everyday life, or create their own short “runestone” containing a message for people living hundreds of years in the future. That last activity can lead to some surprisingly interesting conversations: What would we want people in the future to know about us? What would they misunderstand if all they had were a few objects and inscriptions?

A brief history of melancholy

The TED-Ed lesson A brief history of melancholy, created by Courtney Stephens and directed by Sharon Colman Graham, explores how the idea of sadness and melancholy has changed throughout history. Through an animated and accessible format, the lesson explains that melancholy has been understood in many different ways over time: as a medical condition, a philosophical state, a creative force, or simply part of the human experience.

The resource examines historical beliefs such as the ancient theory of the “four humors,” where melancholy was linked to an excess of black bile, and later cultural ideas that connected sadness with wisdom, creativity, or artistic sensitivity. It also reflects on modern views of depression and emotional well-being, encouraging viewers to think critically about how societies interpret emotions.

One of the main strengths of this resource is that it combines history, psychology, philosophy, and culture in a short and engaging lesson. The TED-Ed format also includes discussion questions and additional materials, making it especially useful for educational contexts. Teachers can use it to promote conversations about emotions, mental health, and the historical evolution of ideas related to sadness and human behaviour.

Why is grammar so confusing?

Grammar rules have sparked strong debates across different languages and cultures for centuries. While it is clear that people care deeply about using language “correctly,” it is not always obvious why these rules exist or where they come from. Many of them seem arbitrary, raising questions about whether they truly matter or are simply conventions that have developed over time.

In the video, Arika Okrent explores this issue by examining several well-known examples from English that have generated ongoing disagreement among speakers and writers. Through these cases, the video shows how grammar is not fixed, but shaped by history, usage, and changing attitudes, encouraging viewers to rethink what “correct” language really means.

How did trains standardize time in the United States?

Standard time is the synchronization of clocks within a geographical area or region to a single time standard 

During the 19th century, scheduled trains required time standardization in the industrialized world. 

Standard time was not enacted into US law until the 1918 Standard Time Act established standard time in time zones; the law also instituted daylight saving time (DST). 

This lesson explains some details of the history of time standardization in the United States.

How the world's first subway system was built

The London Underground (also known as the Underground, or by its nickname the Tube) is a public rapid transit system serving London and some parts of the adjacent counties of Buckinghamshire, Essex and Hertfordshire in the United Kingdom.

The Underground has its origins in the Metropolitan Railway, the world's first underground railway. Opened in 1863, it is now part of the Circle, Hammersmith & City and Metropolitan lines; the first line to operate underground electric traction trains, the City & South London Railway in 1890, is now part of the Northern line. The network has expanded to 11 lines, that collectively hadle approximately 4,8 million passengers a day. (Source Wikipedia)

This lesson by TED-Ed teaches how the London subway system was first developed.

A Brief History of Plural Word...s

In order to change a singular noun to its plural form in English, you usually add "s": the plural of pen is pens. The plural of dog is dogs. These are regular plurals. There are many nouns which don't follow this rule. For example, the plural of fish is fish. The plural of man is men. These are irregular plurals.
