Hello, friends! Today, we’re going to explore something really cool called the greenhouse effect. Have you ever heard of it? It’s a natural process that makes life possible on Earth. But why is it important, and how does it work? Let’s find out!
Imagine a greenhouse, which is a special building made of glass or plastic. People use greenhouses to grow plants, flowers, and crops. The walls and roof let sunlight in, which warms up the inside. This warmth helps plants grow by keeping the temperature and humidity just right.
Our planet works a bit like a giant greenhouse. Earth is surrounded by a thin layer of gases called the atmosphere. This layer lets some sunlight in and keeps the planet warm. The atmosphere contains special gases known as greenhouse gases, like carbon dioxide (CO2), which trap some of the sun’s energy and help maintain Earth’s temperature.
Over the years, the amount of greenhouse gases, especially CO2, has gone up. This is mainly because of human activities. Since the industrial revolution, we’ve been using a lot of fossil fuels like coal and oil. Cars, airplanes, and factories release CO2 into the air. Even when we use electricity, we’re often burning fossil fuels, which adds more CO2 to the atmosphere.
With more greenhouse gases, the Earth is getting warmer, similar to how a greenhouse gets warm. This is causing changes like water shortages, deserts spreading, lakes drying up, and sea levels rising. If we don’t act quickly, these problems could get worse in the future.
There are many things we can do to help our planet. We can recycle, use renewable energy like solar and wind power, drive electric cars, and reduce plastic waste. Every little action counts!

Build Your Own Mini Greenhouse: Gather some simple materials like a clear plastic container, soil, and seeds (like beans or small flowers). Plant the seeds in the soil inside the container and place it in a sunny spot. Observe how the container traps heat and moisture, helping the seeds to sprout and grow. Discuss with your friends or family how this is similar to the Earth’s greenhouse effect.
Greenhouse Gas Experiment: Fill two identical clear jars with the same amount of soil and place a thermometer in each. Cover one jar with plastic wrap and leave the other open. Place both jars in a sunny location. After a few hours, check the temperature in each jar. Which one is warmer? Talk about how the plastic wrap acts like greenhouse gases, trapping heat inside the jar.
Observe and Report: Go on a nature walk with a notebook. Look for examples of how plants and animals might be affected by changes in temperature and weather. Write down or draw what you see. Think about how the greenhouse effect might be influencing these changes. Share your observations with your class or family and discuss ways to help protect the environment.

[bright music] – [Announcer] Smile and Learn. – [Narrator] Hello, friends! Today we’re going to learn about the greenhouse effect. Have you ever heard of it? The greenhouse effect is a natural phenomenon that makes life possible on our planet. But why do we talk about the greenhouse effect? Do you know how it works?
Now you’re going to understand it better. A greenhouse is an enclosed structure made of plastic or glass used to grow crops, flowers, or plants. The walls and ceiling allow sunlight to come through, warming the inside of the greenhouse. This way, we maintain temperature and humidity, creating optimal conditions for plants to grow.
The same effect occurs on our planet. The Earth is surrounded by the atmosphere, a thin layer of gases that allows some solar radiation to penetrate. This layer contains gases known as greenhouse gases, which absorb part of the energy received and help maintain the planet’s temperature. One of the main greenhouse gases is carbon dioxide (CO2).
Over the past centuries, the concentration of gases like CO2 in the atmosphere has increased, enhancing its capacity to retain solar radiation and resulting in a rise in the planet’s temperature, similar to what happens in a greenhouse. However, the increase of these gases is detrimental to the Earth.
Why have these gases become more abundant? Since the industrial revolution, CO2 emissions have risen due to the use of fossil fuels like coal and oil. Nowadays, traffic in cities, including cars and airplanes, produces significant amounts of CO2 emissions. Additionally, a large portion of the energy we consume is generated from fossil fuels. Every time you leave the lights on or use an electronic device, you’re contributing to CO2 emissions. Factories are also a major source of CO2 emissions; for example, producing plastic requires fossil fuels and a substantial amount of electrical energy.
Did you know that the textile industry is a significant polluter? Intensive farming also contributes to greenhouse gas emissions, and wildfires release large amounts of CO2 into the atmosphere.
As a result of the greenhouse effect and rising global temperatures, the Earth is undergoing changes. Water shortages, desertification, the disappearance of lakes, and rising sea levels are becoming increasingly common. The worst consequences are predicted for the future if we do not take urgent action.
Currently, there are viable solutions available, such as recycling, using renewable energy, electric transportation, and reducing plastic waste. Would you like to learn more? We cover these topics in our video “Climate Change.” We’re counting on you! Remember, it’s in your hands to care for the planet. Want to join us in our mission?
