Science is the systematic study of the natural world through observation and experimentation. It helps us understand how things work, from the smallest particles like atoms to vast systems like ecosystems. By asking questions and seeking answers, scientists develop theories that explain various phenomena, leading to new discoveries and technologies. Through the scientific method, researchers gather data, test hypotheses, and draw conclusions. This process has led to significant advancements in fields such as medicine, physics, and environmental science. Ultimately, science empowers us to make informed decisions and improve our lives by uncovering the mysteries of the universe.
