Paper is made from trees! π³ When we cut trees, we take the wood and turn it into tiny pieces. Then, we mix these pieces with water to make something like a soup. After that, we spread this soup flat and let it dry. When it dries, it becomes paper! π
We use paper to draw, write, and make books. Isn't that cool? π¨
A satellite is like a little spaceship that flies around the Earth or other planets! πβ¨ Some satellites are made by people, and they help us watch TV, talk on the phone, and even see the weather. Others are natural, like the Moonβitβs Earthβs big, round satellite that glows at night! π
Satellites zoom around in space and send pictures and messages back to us. Theyβre like space helpers! π
Air is like a big invisible blanket around us! π¬οΈ It's made mostly of two special gases called oxygen and nitrogen. We breathe in oxygen to stay alive, and plants love it too! π±
There's also tiny bits of other things in the air, like water and dust. That's why we sometimes see clouds or feel wind!
Time is like a river that never stops! π It moves forward, just like the hands on a clock. You can't see it, but you can feel it when you grow taller or when the seasons change.
Time helps us know when to wake up, eat, play, and sleep. β° It's always flowing, just like water in a stream!
Glass is made from sand! π When sand gets very, very hot, it melts and turns into a liquid. Then, when it cools down, it becomes hard and clear like the glass we see every day. οΏ½
People use glass to make windows, bottles, and even pretty decorations! β¨
Long, long ago, there were big cities and kingdoms where people lived happily. π But sometimes, bad things happened like no rain for a long time (drought), big fights (wars), or sickness. π’ These things made it hard for people to live there, so they had to leave or the cities became empty.
Fun fact: The ancient city of Pompeii was covered by volcano ash, but it kept everything like a time capsule! πΊ
Fir trees stay green all year because they have special leaves called needles! π² These needles are tough and covered with a waxy coating, which helps them keep water inside even when it's cold or dry.
Unlike other trees that lose their leaves in winter, fir trees keep their needles for many years. That's why they always look green and happy! π
π A year is how long it takes for the Earth to go all the way around the Sun! π It takes 365 days to finish this big trip. That's why we have 365 days in a year! π
Every four years, we add one extra day (February 29th) to catch up. That's called a leap year! πΈ
Trees shed their leaves to take a little nap during winter! π³π€ When it gets cold, trees need to save energy, so they drop their leaves and rest until spring comes.
Leaves are like little blankets for trees. But in winter, they would freeze, so trees let them go and grow new ones when it's warm again! π
Gasoline comes from deep underground! π It starts as crude oil, which is like a thick, black liquid. Big machines called oil rigs pump it out of the ground. Then, it goes to a refinery, where it is heated and turned into gasoline. ππ¨
Finally, the gasoline goes to gas stations so cars can use it to move!
