Hello Class 5 students! Today, we are going to learn about the three states of matter: solid, liquid, and gas.
First, let's start with solids. Can anyone give me an example of a solid? That's right, a book, a pencil, or a piece of wood are all examples of solids. Solids have a definite shape and volume, which means they don't change their shape or size easily. When you drop a pencil on the floor, it stays the same shape and size.
Now, let's talk about liquids. Can anyone give me an example of a liquid? Yes, water, juice, or milk are all examples of liquids. Liquids have a definite volume, but they take the shape of their container. For example, when you pour water into a glass, it takes the shape of the glass.
Lastly, let's talk about gases. Can anyone give me an example of a gas? That's right, air, helium, or oxygen are all examples of gases. Gases have neither a definite shape nor a definite volume. They take the shape and volume of their container. For example, when you fill up a balloon with air, it takes the shape of the balloon
In conclusion, the three states of matter are solids, liquids, and gases. Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have neither a definite shape nor volume. We also learned that changing the temperature can change the state of matter.
