①
Galileo Galilei was a famous Italian scientist. He lived about 400 years ago. He made many important discoveries in science. One of them was about the pendulum.
②
The story says that one day, young Galileo was at a church. He saw a lamp swinging from the ceiling. He noticed something interesting. Even when the lamp swung in a big arc, the time of each swing seemed the same.
③
He went home and tested this idea. He used his own heartbeat to measure time. He made pendulums of different sizes. He found out that the time of one swing depends mostly on the length of the string, not the weight.
④
This discovery was used to make better clocks. Pendulum clocks became very accurate. People could finally know the exact time. This changed daily life all over the world.
⑤
Galileo's story teaches us something important. Great discoveries can start from a simple question. We should keep our eyes open and ask "why" about the things around us.

The Edo period lasted from 1603 to 1868. For about 260 years, Japan had peace. There were no big wars. People could focus on their daily lives and culture.

During this time, Japan closed its doors to most foreign countries. This is called "sakoku." Only the Netherlands and China could trade with Japan. This was unusual in world history.

Edo, now called Tokyo, was the biggest city in the world at that time. About one million people lived there. The city had clean streets, public baths, and good water systems. Many people could read and write.

Edo culture was rich. Ukiyo-e woodblock prints were made. Kabuki theater was popular. Haiku poems were written by Matsuo Basho and others. These are still loved today in Japan and around the world.

In 1868, the Edo period ended. Japan opened its doors and changed quickly. But the culture and ideas from the Edo period are still part of who we are. We should be proud of this history.

When plastic enters the sea, it slowly breaks into smaller pieces. Some pieces become very tiny. These are called microplastics. They are smaller than 5 millimeters.
②
Microplastics are a big problem. Small fish eat them by mistake. Bigger fish eat the small fish. The plastic moves up the food chain. In the end, the plastic may reach our dinner table.
③
Scientists have found microplastics in many places. They are in the sea, in rivers, and even in the rain. Researchers say that some people eat about 5 grams of plastic every week. That is the weight of one credit card.
④
What can we do? Don't throw plastic in the street. Use cloth bags. Pick up plastic when you see it. Even small actions help. Some countries are also making new laws to reduce plastic.
⑤
The sea is connected to our life. If the sea is sick, we are sick too. Protecting the sea is also protecting ourselves and our children.
