Top 7 Most Common Questions Children Ask About Rain and the Scientific Answers

Tell your child: You are still young, so your immune system is not as strong as adults. When you stay in the rain for too long, the rainwater soaks into your body, and more importantly, the rain causes bacteria on the ground to splash up and attach to you. Since your immune system is weaker, you are more prone to getting sick than adults.

It's important to know: This is especially true for those with weaker health, as the risk of catching a cold is much higher. The real reason is that when it rains, especially when you get wet and your clothes stick to your body, the surrounding temperature and your body temperature decrease. This weakens your immune system, making it easier to get sick, such as catching a cold or flu. Also, when raindrops hit the ground, they can send bacteria in the dirt into the air, and if your immune system is weakened, breathing in these bacteria makes you more susceptible to illness. Additionally, if you live in an area with pollution, the rainwater might be acid rain, which can actually poison you when you bathe in it. Answering this question will help your child understand how to protect their health better.

Tell your child: Rain is caused by clouds, so it only rains in places where there are lots of clouds. In areas without clouds, rain is very rare.

What you should know: Areas with thick clouds but only light rain occur because raindrops are blown by the wind in a different direction, creating this phenomenon. Another explanation is that the center of the cloud holds the most water, while the edges have less, which is why some spots experience heavy rain, while others see only a light shower.

Tell the child: A cloud that rains but not heavily, while the sun is at an angle to that cloud, so the sunlight isn't blocked by it.

Here's something to note: It's completely normal to experience both rain and sunshine at the same time. The first reason is that the cloud causing rain isn't large enough to cover the entire sky, and the sun is positioned at an angle, meaning the sunlight isn't obscured by the cloud. Additionally, another reason might be that a distant rainstorm, driven by wind, reaches an area where the sky is clear and there's no cloud cover. Rain is a crucial part of life, and explaining this phenomenon helps the child develop a better understanding, laying the foundation for intellectual growth.

Explain to the child: Currently, it is not recommended for children to drink rainwater as it is no longer clean. The air pollution is so severe that harmful substances accumulate in the rainwater, making it unsafe for consumption.

Important to note: In the past, rainwater was considered a pure source and was used for daily activities. However, due to the significant air pollution caused by industrial emissions, harmful fumes from transportation, SO2 gases, dust particles, and various contaminants that rise into the Earth's atmosphere, the rain carries these pollutants down to the ground. Therefore, this explanation will help prevent the child from drinking rainwater without caution.

Explain to the child: On hot sunny days, the heat causes water vapor from rivers, lakes, and other bodies of water to rise into the sky, where it cools and condenses into clouds. When these clouds meet the right conditions, they release water droplets that fall to the earth, and this is what we know as rain.

Important to know: Rain is a key component of the water cycle and is responsible for depositing most of the fresh water on Earth. It creates ideal conditions for many ecosystems, as well as providing water for hydroelectric plants and irrigation systems. This explanation will help the child understand the process of rain, and remind them to conserve water, as a lack of fresh water would make it impossible for humans to survive.

Explain to the child: Long-lasting rainstorms occur when there are many clouds containing large amounts of water, which results in extended rainfall. On the other hand, when the clouds contain less water, the rain is typically short-lived.

Important to know: All rainstorms are a result of two factors: the moisture in the air that helps form clouds, and the upward movement of air. As humid air rises and passes through the clouds, the temperature drops, causing condensation and water to fall as raindrops. Large storms can happen when there is excessive moisture in the air and rapid upward movement. This explanation will help the child understand why some storms are long and others are brief, fostering a better cognitive development as they grasp the science behind weather patterns.

Hãy nói với bé: Cầu vồng là hình ảnh của ánh sáng mặt trời khi chiếu qua những giọt mưa trong không khí, cũng vì thế nên khi mưa vào ban ngày, lúc có ánh sáng mặt trời sẽ có cầu vồng, còn mưa vào ban đêm thì hầu như không thấy có cầu vồng.

Bạn nên biết rằng: Cầu vồng bản chất là sự tán sắc ánh sáng mặt trời khi khúc xạ và phản xạ qua các giọt nước mưa. Cầu vồng thực ra có rất nhiều màu sắc, nhưng chúng ta chỉ thấy có 7 màu nổi bật là đỏ, cam, vàng, lục, lam, chàm, tím. Ánh sáng mặt trời là một hỗn hợp các màu sắc hòa trộn vào nhau mà mắt chúng ta không thể phát hiện ra các màu sắc này. Chỉ khi được chiếu qua các giọt mưa, các tia ánh sáng bị bẻ cong hay còn gọi là khúc xạ để tạo thành một dải màu sắc liên tục. Do các tia màu đỏ bị bẻ cong ít nhất, sau đó đến các tia màu cam, vàng, xanh lá cây, xanh lam và cuối cùng là tia màu tím bị bẻ cong nhiều nhất. Màu sắc của cầu vòng rất dễ thu hút sự chú ý của bé, nếu bé chưa biết rõ từng màu, hãy chỉ dạy bé thêm về từng màu nhé.
