Scandinavism is like when you have 3 best friends and you guys always play together, and you always help each other out. The 3 best friends are Sweden, Denmark, and Norway, and they are all in the same family of countries called Scandinavia.
They are like brothers and sisters who live together and share things like food, language, and culture. They have a lot in common and they like to work together to make things better for everyone.
Scandinavism is about them working together even more, like a superhero team, to make their family of countries even better. They want to help each other out more and learn even more about each other's cultures.
Just like when your friends help you with your homework and you help them too, the countries of Scandinavia want to help each other out with things like trade, politics, and education. They believe that by working together, they can make their family of countries even stronger and more successful.
