Hello there! Today, we’re going to learn about something super cool: the states of matter. Imagine it’s a hot day, and you’re making yummy strawberry popsicles. To keep them solid, you need to put them in the freezer. But what does it mean for something to be solid? Let’s find out!
Matter is what everything around us is made of. It can be in three different states: solid, liquid, and gas. Let’s explore each one!
Solids are things like your popsicles. They have a shape that doesn’t change, and their particles are packed tightly together. This is why solids feel hard and firm.
Liquids are like the strawberry juice you use to make popsicles. They take the shape of the container they’re in, but their volume stays the same. The particles in a liquid are a bit more spread out and can move around, almost like they’re dancing!
Gases are like the steam coming from a pot of boiling water. They can change shape and volume, filling up any space they’re in. The particles in a gas are far apart and move around freely.
Now, let’s talk about how matter can change from one state to another. This happens when we heat or cool it.
When you heat a solid, like ice, it turns into a liquid. This process is called fusion. The particles start to move more freely as they warm up.
If you heat a liquid, like water, it becomes a gas. This is called vaporization. The particles move even more freely and spread out.
When a gas cools down, it turns back into a liquid. This is called condensation. The particles come closer together and slow down.
Finally, when you freeze a liquid, it becomes a solid. This is called solidification. The particles get very close and stop moving as much.
Let’s recap what we’ve learned about the changes in states of matter:
Now you know all about the states of matter and how they change! Isn’t that fascinating? I hope you enjoyed learning about this. Now, I’m off to make more popsicles. See you next time!
Ice Cube Experiment: At home, with the help of an adult, take an ice cube and place it in a bowl. Observe what happens as it melts. Can you describe the changes you see? Once it has melted into water, ask an adult to help you heat the water in a pot until it turns into steam. What do you notice about the steam compared to the ice and water? Try to draw each state of matter: solid (ice), liquid (water), and gas (steam) in your notebook.
State of Matter Scavenger Hunt: Go on a scavenger hunt around your house or classroom to find examples of solids, liquids, and gases. Write down or draw at least three examples of each state of matter. For example, a solid could be a book, a liquid could be juice, and a gas could be the air you blow into a balloon. Share your findings with a friend or family member and explain why each item fits into its category.
Question Time: Think about your favorite drink. What state of matter is it in? What would happen if you put it in the freezer? What if you heated it up? Discuss with a friend or family member how the drink would change and what processes (fusion, vaporization, condensation, solidification) would be involved.
Sure! Here’s a sanitized version of the YouTube transcript:

Hello! It’s a hot day, and I’m making some strawberry popsicles. To keep them solid, I need to put them in the freezer for a while.
Do you know what a solid is? It’s one of the states of matter. Let me explain!
Matter is the substance that all things are made of, and it exists in three states: liquid, like this strawberry juice; solid, like this popsicle; and gas, like the water vapor coming from this pot.
Everything we drink is in its liquid state. Liquid matter takes the shape of its container, and its volume remains constant. The particles in a liquid are separated and can move freely, almost like they’re dancing!
Popsicles are solid matter. Solid matter has a fixed shape and volume, with particles held together in an organized structure.
Now, let’s talk about the gaseous state. The vapor from the pot is a gas. Gas can change its volume and shape, filling the space of its container, with particles that are well separated and can move freely.
To recap:
– Matter exists in three states: solid, liquid, and gas.
– Solid matter has a definite shape and volume, with closely packed particles.
– Liquid matter takes the shape of its container, with particles that are separated and can move freely.
– Gas matter has no fixed shape or volume, with particles that are well separated and can move freely.
That’s all about the states of matter! Interesting, right?
Now, I’m going to make some more popsicles to sell. They taste so good, and I’m sure they’ll sell quickly! These are ready; they’ve become solid because I put them in the freezer.
Have you heard of solidification? It’s one of the changes in states of matter. There are more changes, and I’ll explain them.
As you know, matter exists in three states: solid, liquid, and gas. A change in state happens when we heat or cool matter.
If we heat solid matter, it becomes a liquid, which is called fusion. If we heat liquid matter, it becomes a gas, known as vaporization.
These processes can also occur in reverse. When we cool matter, if we cool a gas, it becomes a liquid (condensation), and if we freeze a liquid, it becomes a solid (solidification).
Oh no, the popsicles have melted! I forgot about them. Remember, when a solid becomes a liquid, it’s called fusion. When the temperature of a solid rises, the particles start to detach and move more freely.
Liquid turns into gas when heated. When a liquid becomes a gas, it’s called vaporization. As a liquid is heated, the bonds among the particles loosen, allowing them to move around freely.
If I cover this pot, what do you think will happen? The water vapor cools as it reaches the lid, changing from gas to liquid, which is called condensation. As a gas cools, the particles come closer together and move more slowly until the matter solidifies completely.
I think the popsicles I froze earlier are ready! The liquid in the molds must have frozen by now. The change from liquid to solid is called solidification. During this process, the particles lay close together and move less.
To recap the changes in states of matter:
– Heating solid matter turns it into a liquid (fusion).
– Heating liquid matter turns it into a gas (vaporization).
– Cooling a gas turns it into a liquid (condensation).
– Freezing liquid matter turns it into a solid (solidification).
Now you know all about the changes and states of matter! I hope you find this information useful in class. I have to go check on all those people lining up for popsicles. See you around!
