So imagine you have a big jar of honey that belongs to you. That honey is like Scotland's oil. Just like honey, oil is a valuable resource that comes from the ground and can be used for many things like making electricity, fueling cars, and making things like plastic.
Now, some people think that Scotland should be allowed to keep all the money they earn from selling their oil just like you would keep all the money you earn from selling your honey. But other people think that Scotland should share the money with the rest of the country, just like sometimes you might share your honey with your friends or family.
It's a big debate, but it's important for Scotland because oil is an important resource and can mean a lot of money for the country.
