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.

It’s time to prepare for her weekend in Amsterdam. Our friend packs her clothes, toiletry bag, things to read, and a few other essentials. Will she need an umbrella?

This lucky girl has her birthday next week and is planning a trip with friends. She plans a train trip through France and Belgium, and books the perfect hotel in Amsterdam. She has lots of ideas for things to see and do in the city, and some new food she wants to try.

Sigrid uses the question words "who," "what," "when," "where," "why," and "how" as she thinks out loud about her next vacation. Where will she go? How will she get there? How much will it cost?

We often use question words to ask questions. The five main ones start with "wh." Sigrid explains how they work.

Jessica takes us on a walk through Prospect Park. She stops several times to point out and describe various objects along the way.

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.

The Bronx was the first area to become part of New York City. Lying to the north and northeast of Manhattan, it was a logical addition. The quirky name of this borough has its own history.

Sigrid seeks to answer the question "What's a borough?" In doing so, she talks about how New York City got its start, and also about the surrounding counties that played an important role in its development. In this video, you'll see 18th- and 19th-century maps of the area.

Sigrid describes the first part of her trip from Long Island to New Jersey, taking a moment to tell us about the famous Verrazzano Narrows Bridge.

Sigrid traveled back to the U.S. recently to visit her family. She talks about her trip and takes some "detours" to share what she learned about some of the places she visited. She also happened to go to Mexico, where she shot this introductory segment.
