Science is the systematic study of the natural world through observation and experimentation. It helps us understand the laws of nature, such as gravity and evolution, and how different elements interact. Scientists use the scientific method to test hypotheses and gather data, leading to discoveries that improve our lives and expand our knowledge. Nature encompasses all living and non-living things on Earth, including plants, animals, and ecosystems. It is a complex web of interactions, where each organism plays a role in maintaining balance. Understanding nature is crucial for conservation efforts and sustainable practices, ensuring that we protect our environment for future generations.
