John Dalton was a scientist from England who lived in the late 1700s and early 1800s. He was very curious about nature, especially the weather. Even as a boy, he loved to observe the sky, measure rainfall, and study how the air changed. He kept careful weather records for over 50 years, writing down details about temperature, rain, and air pressure every single day. His observations helped people better understand weather patterns and how they change over time.
Dalton also made important discoveries about the water cycle. He studied how water moves through the air, turning into clouds, rain, and back into rivers and oceans. He was one of the first scientists to explain how evaporation works and how water turns into gas when it heats up. He also studied how air holds moisture and how different temperatures affect the amount of water in the air. His ideas helped scientists learn more about the movement of water in nature, which is an important part of weather and climate.
Besides studying the weather, Dalton is most famous for his atomic theory. He discovered that everything in the world is made of tiny building blocks called atoms. His ideas about atoms helped scientists understand how different materials form and combine, which became the foundation of modern chemistry.
Dalton also studied color blindness, a condition that made it hard for him to see certain colors. Even though he couldn’t see some colors clearly, he never stopped exploring and asking questions about the world. His work helped people understand atoms, weather, and the water cycle, and his curiosity continues to inspire scientists today!
