Doodling is like drawing! You can make shapes, lines, or anything you want! It might look like you’re just scribbling, but doodling is different. Doodling creates pictures you can recognize, while scribbling is just random and messy lines.

When kids doodle while they listen, they understand things better. Pictures help make abstract and complex ideas concrete, simple, and easier to understand. Pictures also help them remember more of what they hear. Why? Because when you see words and pictures together, your brain remembers them in two ways—with words and with pictures. This makes your memory stronger. Even if you forget the words, your drawings can help you recall them. In other words, drawings can act as memory triggers.

So, next time you’re in class, have a pen with you. Those little doodles might help you remember more than you think!

What kinds of factors affect the results of a baseball game? Surprisingly, the weather is one of the most important factors. Weather affects the density of air, which plays a key role in baseball. On cold, dry days, the air is thick. On hot, humid days, it is thin. This means a baseball travels farther in warm weather. When do batters hit the most home runs? It is usually in the summer, especially during the rainy season. This is because it is warmer and more humid then. For example, in the MLB season, the average number of home runs per game in July is higher than in April. Home runs are more common in high-altitude areas, too. Why? In high places, the air is thin, so the ball travels farther. This explains why the most home runs in the Major Leagues have been hit at Coors Field in Colorado, near the Rocky Mountains.

03 자연을 소비한 나라, 미래를 잃다

Would you trade your future for quick money? That’s what happened in Nauru, a tiny island country in the Pacific Ocean. It is one of the smallest countries in the world, both in area and in the number of people.

A long time ago, people found a lot of phosphate rock on the island. This phosphate rock was formed from bird droppings and is a useful mineral. It is used to make fertilizer for farming. Many companies came to mine the phosphate rock, and Nauru became rich. But there was a big problem. The mining hurt the land. The middle of the island became empty and broken. Most of the natural land and plants were destroyed. After many years, the phosphate rock started to run out.  When it was nearly gone, Nauru lost its wealth.

Today, the country has many problems like poverty and a damaged environment. Nauru’s story gives us an important lesson. If we use too much from nature without care, it can hurt us later. Nauru was once rich, but thinking only about quick money caused big problems. We should use nature wisely and protect it for the future.
