Westernization: The adoption of western ideas, technology, and culture. It's like switching from traditional clothes to jeans and t-shirts because you want to look more "American".
Industrialization: The process by which an economy is transformed from primarily agricultural to one based on manufacturing. Imagine if your school went from growing its own food in a garden to having it all made in a high-tech kitchen.
Imperialism: A policy or ideology where a nation extends its power by acquiring territories. It’s like the school bully who keeps taking over other kids' spots on the playground.
