Hey there! Today, we’re going to learn all about weather. Have you ever wondered why you need a coat on some days and a swimsuit on others? That’s because of the weather! Knowing what the weather is like helps us decide what to wear and what activities to do.
Weather is what it’s like outside at any time of the day. It can be hot or cold, wet or dry, clear or cloudy, and calm or stormy. These changes happen because of a layer of gases around Earth called the atmosphere. The atmosphere keeps us safe and helps control the temperature on our planet.
The weather can be different depending on where you live. Places closer to the equator, an imaginary line around the middle of the Earth, are usually warmer. If you live near the ocean, your weather might be different from someone who lives near mountains.
A meteorologist is a person who studies and predicts the weather. You might have seen them on TV, standing in front of a weather map and telling us what the weather will be like during the week.
Weather can be hot, cold, or in between. We measure how hot or cold it is with a thermometer, which tells us the temperature in degrees. The faster the gas molecules in the air move, the hotter it gets.
Have you ever felt the air near the ocean or in a desert? That’s because of humidity, which is the amount of water vapor in the air. If there’s a lot of water vapor, it might rain! We measure humidity with a tool called a hygrometer.
Air pressure affects whether it’s clear or cloudy. Air pressure is the weight of the atmosphere pressing down on Earth. We measure it with a barometer. High pressure usually means sunny weather, while low pressure can bring clouds and rain.
Wind is air moving from high-pressure areas to low-pressure areas. It can be a gentle breeze or a strong gust, depending on the land around it. We measure wind speed with an anemometer.
Now that you know about weather, here are some fun questions to test your knowledge:
Great job! No matter where you live, weather is always around you. Next time you’re outside, try to figure out what the weather is like using what you’ve learned today.
We hope you had fun learning with us! Visit us at learnbrite.org for more fun resources and activities.
Weather Journal: Start a weather journal! Each day, observe the weather outside and draw a picture of what you see. Is it sunny, cloudy, rainy, or windy? Write a few words about how the weather feels. At the end of the week, look back at your drawings and see if you can spot any patterns. Did the weather change a lot, or was it mostly the same?
DIY Weather Station: Create your own simple weather station at home. Use a plastic bottle to make a rain gauge by marking measurements on the side to see how much it rains. Make a wind vane using a straw, paper, and a pin to see which way the wind is blowing. Check your weather station each day and record your findings in your weather journal.
Weather Detective: Become a weather detective by watching a weather forecast on TV or online. Listen to the meteorologist and see if you can understand what they are predicting. Then, look outside and see if their predictions match what you observe. Discuss with a family member why predictions might sometimes be different from what you see.
Sure! Here’s a sanitized version of the transcript:

Today, we are talking all about the weather. There’s a good chance that when you woke up this morning, you probably checked the weather. That is because it is important to know when to wear a heavy coat and snow boots and when to put on a swimsuit. You would not wear a coat in the heat or a swimsuit in the cold, so learning about what weather is and how to predict it is pretty useful information.
So, what is weather exactly? Weather describes what it is like outside at any given time of day. It can be hot or cold, wet or dry, clear or cloudy, or calm or stormy. Most of the time, it is at least a few of these things all at once. These changes in weather are because of a layer of gases that surround the Earth called the atmosphere. The atmosphere also acts as a shield, protecting life and helping keep our planet at a safe temperature.
Weather also depends on a place’s distance from the equator, which is an imaginary line that separates the northern and southern halves of the Earth. The closer a place is to the equator, the warmer it will be. In fact, where you live on the planet has a huge impact on what weather you will see. For example, the weather near the ocean is often a lot different than the weather near a tall mountain range.
Here is an interesting fact: a meteorologist is a person who studies and predicts the weather. You might have even seen a meteorologist sometime on the news. They are the people who stand in front of a weather map and give forecasts or educated predictions of what the weather will be like during the week in the area where you live.
Now that we have talked about what weather is, let’s talk about the different types of weather and how each is measured.
**Hot or Cold**
Weather can be hot or cold or somewhere in between. The way that this hotness or coldness is measured is by temperature, which is based on the motion of energy and the speed of gas molecules in the air. If the gas molecules are moving faster, the temperature will get higher, meaning that the weather gets hotter. Can you guess what is used to determine temperature? That is right, it is a tool called a thermometer, and it measures temperature in units called degrees.
**Wet or Dry**
Have you ever been near the ocean? What about a desert? The air around you can feel different depending on where you are in the world. This difference is called humidity, which tells us the amount of water vapor in the air. Even though you cannot see this water, you can definitely feel it. The higher the humidity, the more moisture or water vapor there is in the air. Here is another interesting fact: if there is too much water vapor, it will begin to rain. Humidity is measured by a tool called a hygrometer.
**Clear or Cloudy**
Did you know that air pressure affects whether or not it is a clear or cloudy day? Remember when we talked about the atmosphere? Well, air pressure is the weight of the atmosphere pressing down on the Earth, which is why it is also sometimes called atmospheric pressure. Like humidity, air pressure affects all parts of the weather each day. How is air pressure measured, you ask? By a tool called a barometer. There are two types of air pressure: high and low. High pressure usually means that the weather will be fair and sunny, while low pressure brings clouds, rain, or snow.
**Calm or Stormy**
When you find yourself stuck in a storm, you might notice that wind is almost always involved. Wind is air moving from higher pressure areas to lower pressure areas. Wind speed is also affected by the heating of the Earth’s surface and the rotation of the Earth. The speed of wind can also be changed by the landforms around it, such as mountains, bodies of water, and vegetation. This is why sometimes the wind can start as a gentle breeze and then change into a strong gust. The speed of wind is measured by a device called an anemometer.
Now that is a fascinating fact you can share with a friend!
Are you ready to review what we have learned? Let’s go!
**True or False:** A paleontologist studies and predicts the weather.
**False.** A meteorologist studies and predicts the weather; a paleontologist studies fossils.
**Fill in the blank:** ______ tells us how much water vapor is in the air at a given time.
**Humidity.**
**What is the name of the protective layer of gases that surround the Earth?**
**The atmosphere.**
**True or False:** A barometer measures air pressure.
**True.**
**Name one type of weather that we discussed today.**
You’re right! Hot or cold, wet or dry, clear or cloudy, or calm or stormy.
Great job! No matter if you live near the equator or on top of a tall mountain, you will always be surrounded by weather. The next time you are outside, try to see if you can figure out exactly what the weather is like using all the information you have learned today.
