Classifying solids, liquids, and gases can be tricky when we study matter. They each have their own special qualities that make them different:

1. Solids:

   • Solids have a set shape and a set amount of space they take up.
   • The tiny bits, called molecules, are packed tightly together, so they don’t move around much.

2. Liquids:

   • Liquids have a set amount of space, but they change shape to fit their container.
   • The molecules are close together but can flow around, which makes them a bit harder to understand.

3. Gases:

   • Gases don’t have a set shape or amount of space. They spread out to fill any area.
   • The molecules in gases are spread apart and move freely, adding to the confusion.

We can make these ideas easier to understand by doing hands-on experiments, using models to see what they look like, and having clear demonstrations. This way, even if it seems confusing at first, we can learn better!
