When you think about expand, think of a balloon. When you blow air into the balloon, it gets bigger and bigger. The balloon is expanding because it has more air inside, making it grow in size. Just like that, when something expands, it means it is getting larger or taking up more space.
Another way to think about expand is like a sponge. When you put a dry sponge in water, it soaks up the water and becomes bigger and softer. The sponge expands because it absorbs the water, making it grow.
Imagine a rubber band. When you stretch it, it becomes longer. This stretching is another form of expanding. The rubber band is expanding because you’re pulling it, making it take up more space.
Lastly, think of a tree growing. When you plant a tiny seed, it slowly grows into a big tree over time. As it grows, it expands, spreading its branches and leaves to become larger and provide shade. So, expanding can also mean growing over time, like a tree getting bigger and stronger.
