Let's look at how Long Island was formed around 20,000 years ago. It has to do with a glacier that brought plenty of material along with it and left some behind when it receded.

Let's have a look at which countries are members of the European Union and where they are on the map.

Sigrid explains how a spelling bee normally proceeds. There are fixed rules and there are options.

Let's find out more about an American activity aimed at school kids: the spelling bee. What is it and how does it work?

Sigrid talks about "The Elementary Spelling Book" by Noah Webster, which was the basis for the American English dictionary and a big part of the development of spelling bees in the United States.

We keep seeing the "Black Lives Matter" slogan all around — what's it all about? Well, it's a long story. Here's part of the story in a nutshell.

What a time to be learning English! Things are happening quickly in the United States and history is being made right now, so don't miss out on the words and expressions you need to know.

Everyone should stay home as much as possible to keep the coronavirus from spreading, but sometimes we have to go out for essential errands. What are some items to have on hand when we go out? Sigrid talks about five of them.

For so many of us, life has changed radically. We've had to learn new habits because of the coronavirus pandemic. Here are some of the changes we are having to make.

Sigrid describes traveling from her home in Italy to Tacoma, Washington in the United States to care for her sister with Alzheimer's disease. She stayed there for a whole month.

Finally home! Sigrid talks about her trip home and how it feels to be back after a month away.

For the final days of Sigrid's visit to the New York area, she leaves the rocky North Shore and goes south to a place she knows very well from her childhood—the beach! It's a nice place to visit even in the cooler weather.

We're back on Long Island, exploring the North Shore with an outing to a wildlife refuge on one of the necks, or small peninsulas that jut into the Long Island Sound, the body of water separating Long Island from Connecticut.

This last part about the D&R canal talks about the special bridges that were needed to cross the canal and who had to take care of them. And if you're wondering if the canal is still in use, Sigrid answers that question. There's a special tribute at the end of the video for which you might want this link.

What makes canals so special? In part 2, we explore locks. Locks are like elevators for barges and boats!

After exploring the five boroughs of New York City, we move on to Princeton, New Jersey, where Sigrid gets curious about a canal built in the early 19th century.

In part 2 about the borough of Manhattan, Sigrid completes her overview of all 5 boroughs of New York City. She talks about some nicknames for New York City, including "the Big Apple."

We've finally made it to Manhattan, the smallest but most densely populated borough. When we think of New York City, Manhattan is more often than not what comes to mind. This is part 1.

It's time to have a look at Staten Island, the 4th borough out of 5. It looks closer to New Jersey than to the rest of New York City and has some other peculiarities.

To get from eastern Long Island to the city, travelers and commuters have to go through Queens, so this borough naturally became a very important transit hub, with Jamaica at its center. It also became crisscrossed with many expressways for vehicles.

Having explored the Bronx and Brooklyn, Sigrid now tells us all about Queens, which is geographically speaking the largest of the 5 boroughs of New York City.

Sigrid talks about the different ways to get from Brooklyn to Manhattan, and about some of the characteristics of this borough. For one thing, it is more affordable than Manhattan, although by no means a cheap place to live.

In the first of two parts, we look at Brooklyn's beginnings and how it came to be one of New York City's boroughs.

The borough of the Bronx has gotten a bad name because of issues with poverty and crime. It's also had its share of neglect and mishandling on the part of local and state administrations. However, the Bronx also has some claims to fame, such as the Bronx zoo and botanical garden.
