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!
🌋 Volcanoes erupt because there is hot, melted rock called magma deep inside the Earth. When the magma gets too hot and bubbly, it pushes up through cracks in the ground and comes out as lava! 🌋💥
Imagine shaking a soda bottle and then opening it—the bubbles rush out! That's kind of like how a volcano erupts!
Radiation is like tiny invisible waves or little energy particles that come from some things around us. 🌟 Some radiation is good, like the warm sunlight that helps plants grow! But some can be not so good, like when we use sunscreen to protect our skin.
Radiation can come from the sun, rocks, and even some machines in hospitals. Doctors use special kinds of radiation to take pictures of our bones! 🏥
There are so many stars in the sky that we can't count them all! 🌟 They twinkle like tiny lights at night.
If you look up, you might see hundreds, but there are actually billions and billions of stars in space! ✨
🌠 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!
🌪️ A tornado is like a big, spinning wind tunnel! Inside, there's lots of strong wind that goes round and round very fast. It can pick up things like leaves, dirt, and even toys if they're outside! 🌬️
But don't worry—tornadoes are far away and grown-ups keep us safe when they happen. Tornadoes are like nature's vacuum cleaners, but they're very loud and scary!
A nuclear power plant is like a big, super-hot teapot! 🚀 It uses tiny things called atoms to make heat. This heat turns water into steam, which spins a big wheel called a turbine. The turbine makes electricity that powers our homes and toys! ⚡
It's safe because scientists and engineers make sure everything is controlled and protected. 🌍
Trains move on special tracks called rails! 🚂💨 They have big, strong engines that pull all the train cars behind them. The wheels of the train are shaped perfectly to stay on the rails so they don't fall off!
When the train driver pushes the controls, the engine makes a loud choo-choo sound and starts moving forward or backward. Trains can go very fast because their wheels roll smoothly on the rails!
The sea is blue because it reflects the color of the sky! 🌞 When the sun shines, the sky looks blue, and the water copies it like a big mirror. Sometimes, the sea can also look green or gray, depending on the weather and what's inside the water.
💡 Fun fact: Did you know that if you take a cup of sea water, it will look clear, not blue? The blue color only shows when there's a lot of water together!
