Hello everyone! Have you ever wondered what the weather is like today? Let’s take a peek outside. Oh, it’s cold and raining! Definitely not a day for the beach! For a long time, people have been looking outside to figure out the weather, but now we have cool tools to help us. These tools are used by meteorologists, who are scientists that study the weather. They use these tools to make predictions about what the weather will be like. It’s like using science to do magic!
One of these cool tools is called a rain gauge. A rain gauge measures how much rain, snow, or hail falls from the sky. It’s like a special cup that you leave outside to catch the rain. After it rains, you can see how much water is in the cup and know how much it rained. The rain gauge has marks on the side to help you measure the water.
If a lot of rain is collected, meteorologists might predict floods. If there’s very little rain, they might predict droughts, which is when there’s not enough water. Did you know that droughts can happen because of global warming? That’s why it’s important to save water and take care of our planet!
Another interesting tool is the hygrometer. A hygrometer measures relative humidity, which is how much water vapor is in the air. Think of it like a big sponge in the sky. If the sponge is really wet, the humidity is high. If it’s only a little wet, the humidity is low.
Most hygrometers today are digital, but some use materials like cloth or paper that change size when they get wet or dry. This movement helps show the humidity level. Indoors, it’s good to have a humidity level between 30% and 60%. Outside, high humidity can make it feel hotter or colder than it really is. It can also mean it might rain or storm soon.
So, rain gauges help us know how much rain has fallen, and hygrometers tell us how humid the air is. There are even more weather tools to learn about, so stay tuned for the next episode!
Wow, the rain stopped! Time to head to the beach. See you later!

Create Your Own Rain Gauge: With the help of an adult, make your own rain gauge using a clear plastic bottle. Cut the top off and invert it to create a funnel. Mark the sides with a ruler to measure the rain. Place it outside and check it after a rainy day. How much rain did you collect? Discuss with your family why measuring rain is important.
Humidity Experiment: Take a small sponge and dip it in water. Squeeze out the excess water and place it in a sealed plastic bag. Leave another dry sponge in a different bag. After a few hours, feel both sponges. Which one feels wetter? Talk about how this relates to humidity and how a hygrometer works.
Weather Journal: Start a weather journal for a week. Each day, observe the weather and write down if it rained and how humid it felt. Use your rain gauge to measure any rainfall. At the end of the week, look back at your notes. Did you notice any patterns? How did the weather change throughout the week?
Sure! Here’s a sanitized version of the transcript:

Hello everyone! What’s the weather like today? Let’s look out the window. It’s cold and raining. Today is definitely not a beach day! To know what the weather is like, we can look outside and observe it with our senses, like I just did here. Humans have been doing this for thousands of years, but it’s a bit old-fashioned, don’t you think?
Today, meteorologists, or scientists who study weather, use instruments to observe weather patterns. By studying and measuring patterns in precipitation, humidity, atmospheric pressure, temperature, or wind, meteorologists can predict the weather. It’s all about making predictions based on science. Sometimes it seems like magic!
Today, I’m going to show you some weather instruments that tell us about precipitation and humidity. By the end of this video, you will know all about these fascinating instruments. Let’s get started!
**Rain Gauge**
The rain gauge is an instrument that measures precipitation, or water in the form of rain, snow, or hail that falls from the sky. There are several types of rain gauges, but this one is the simplest. It’s a container that you place in a flat, open area to collect rainwater. It has an open top to let water in. After it rains, you measure the water in the container and record the total amount of rain that fell.
When we look at a rain gauge, we can see the marks on the side that indicate the amount of precipitation that fell. If meteorologists see that it has rained a lot, they can predict floods. On the other hand, if they see that it has rained very little, they can predict droughts. Did you know that droughts can happen because of global warming? When the Earth warms up, it can affect normal rainfall patterns, so some places don’t get as much rain as they need. That’s why it’s important to take care of the planet and be mindful of water consumption—every drop counts!
**Hygrometer**
A hygrometer is an instrument that measures relative humidity, which is the amount of water vapor that the air can contain. Imagine that relative humidity is like a giant sponge in the air. The sponge can absorb water. If the sponge is really wet, we say that the relative humidity is high, but if it’s only a little wet, the relative humidity is low.
Most hygrometers today are digital and use sensors, but the simplest ones work with a material such as cloth or paper in a frame connected to a needle. When there is high humidity, the material expands, and in a dry environment, it shrinks. This movement moves the needle to point to the percentage of relative humidity.
Indoors, a relative humidity of anywhere from 30% to 60% is recommended. Outdoors, high relative humidity can make the heat or cold feel more extreme. It can also suggest that it might rain or even storm.
In short, rain gauges measure the amount of water that falls from the sky, and hygrometers measure the amount of relative humidity in the air. There are still a few more weather instruments to discover, so don’t miss them in the next episode!
Wow, it stopped raining! I’m going to the beach. See you later!
