Medicines are like tiny helpers inside your body! ๐ฆธโโ๏ธ When you're sick, they fight the bad germs or fix what's not working right. Some medicines are like warriors that beat the germs, while others help your body feel better by reducing pain or fever.
For example, when you have a fever, a medicine can tell your body to cool down. It's like magic, but it's science! ๐
Rivers start when tiny drops of water from rain or melting snow come together! ๐ง๏ธ They flow down hills and mountains, joining other little streams. The more water they collect, the bigger they grow, just like a river! ๐๏ธ
Rivers love to travel and can go very far, sometimes all the way to the ocean! ๐
A galaxy is a huge group of stars ๐, planets, and space dust that all stick together because of gravity. Imagine it like a big, sparkly city in space! Our home, the Earth, is in a galaxy called the Milky Way ๐ฅ.
Galaxies come in different shapesโsome look like spinning pinwheels, and others are round like balls!
Our muscles are like little rubber bands inside our body! ๐ When you want to move, your brain tells your muscles to stretch or squeeze. That's how you run, jump, or even hug your teddy bear! ๐ค
Muscles work in pairs: when one pulls, the other relaxes. Try bending your armโyour biceps (the muscle on top) gets hard, and the triceps (underneath) relaxes! Cool, right? ๐
A shooting star ๐ is not really a star! It's a tiny piece of rock or dust from space that falls into our sky. When it moves very fast, it gets hot and glows brightly like a little sparkle โจ. It looks like a star is falling, but it's just a space visitor saying hello!
Next time you see one, make a wish! ๐
Satellites stay in space because they are moving super fast! ๐ Just like when you swing a ball on a string, it goes around and around. Satellites zoom around the Earth so quickly that they don't fall down. ๐โจ
They are like little space cars driving in circles around our planet!
Fingerprints are the tiny lines on your fingers! ๐ค They help you hold things tightly, like your favorite toy or a yummy cookie. ๐ช
Every person has unique fingerprintsโno two are the same! Even twins have different ones! ๐ถ๐ถ
Some people need glasses because their eyes don't see things clearly, just like when a camera lens is a little blurry! ๐โจ Glasses help their eyes see better, like magic windows that make everything sharp and bright.
Imagine trying to read a book with smudgy glassesโit's hard! That's why some people wear glasses to help their eyes work better. ๐
Nails are like tiny shields for your fingers and toes! ๐ก๏ธ They help protect the soft skin underneath when you touch things or bump your toes.
Nails also help you pick up small things, like toys or food. ๏ฟฝ
Some rocks have shiny crystals inside because they were made very slowly deep underground! ๐โจ When hot melted rock (called magma) cools down over a long time, tiny crystals grow inside it like magic. The slower it cools, the bigger the crystals!
Imagine making ice cubesโif you freeze water slowly, you get big ice cubes. But if you freeze it fast, they stay small. Rocks with crystals are like that too!
