Okay kiddo, so you know when you go to school and have different subjects like math, science, and history?
Well, there are lots of scientists all over the world who study different things like animals, the environment, and outer space. They all do their own research and come up with new ideas and discoveries.
The International Science Council is like a really big group of all these scientists from different countries all over the world. They all work together to share their discoveries and ideas with each other so everyone can learn more about science.
The Council helps these scientists communicate with each other and work together on big science projects that might be too hard for just one scientist or one country to do on their own.
So, it's like they're all part of one really big science class, working together to make science better and help everyone learn more about the amazing universe we live in!
