🌬️ Sand dunes form when the wind blows sand into piles! Just like when you play with sand at the beach, the wind picks up tiny grains of sand and drops them in one place. Over time, these piles grow bigger and bigger, making sand dunes!
🏝️ Some dunes are small, and some are as tall as houses! They can even move slowly when the wind keeps blowing.
Some people live in igloos because they live in very cold places like the Arctic! 🥶 Igloos are made of snow and ice, which keeps them warm inside. It's like a cozy snow house! 🏠❄️
People who live in igloos are called Inuit. They are very smart and know how to build strong igloos to stay safe from the cold wind.
Some people live in boats because they love the water! 🌊 Boats can be like tiny floating houses. They can move around and see new places every day. It's like having a home that can travel on the sea or a river!
Living on a boat is fun because you can see fish 🐟 and waves every morning. Some people also live on boats to be close to nature and enjoy the calm water.
Some people live in caves because caves are like nature's cozy homes! 🌍🏠 Long ago, people used caves to stay safe from wild animals and bad weather. Even today, some people live in caves because they are cool in summer and warm in winter. It's like having a house made by Earth itself! 🌞❄️
Parents can show pictures of cave houses to make it more fun!
Some people live in treehouses because they are fun! 🌟 It's like having a secret hideout up high in the trees where you can play and imagine adventures. Treehouses can also keep you safe from animals or floods in some places.
Parents sometimes build treehouses for kids to play in, or even for the whole family to enjoy nature together! 🏡
🌞 Polar day is when the sun doesn't go to bed at all! It stays up in the sky for many days or even months! This happens in places very far north or south, like where Santa Claus lives! 🎅
🌚 Polar night is the opposite—the sun takes a long nap, and it's dark for many days or months. Brrr, that sounds cold! ❄️
This happens because the Earth tilts like a spinning top, and some places get extra sun or extra darkness.
The Moon doesn't fall to Earth because it's always moving around us, like a big ball swinging on a string! 🌍🌕
Imagine you're spinning a ball on a string—it doesn't fall because it's moving fast. The Moon moves super fast around Earth, so it stays up in the sky!
Glass breaks because it is hard but not very bendy! 🪀 When you push or hit it too hard, it can't stretch like rubber, so it cracks into pieces.
Imagine if you had a cookie 🍪 that was very crispy. If you bent it, it would snap instead of bending. Glass is a bit like that!
White nights are when it stays light outside even at night! 🌞 It happens in places near the North and South Poles. The sun doesn’t go down completely, so it’s never really dark.
Imagine playing outside at bedtime, and it’s still sunny! That’s what white nights are like. Some people even have parties because it’s so special!
🌠 The universe is like a big, big balloon that is growing! There is no center because it grows everywhere at the same time. Imagine you are a tiny dot on the balloon—where is the center? Everywhere! 🎈
So, the universe doesn't have a center—it's just all around us, stretching and growing!
