A scientist is a person who studies things and tries to understand how they work. They use experiments and observation to gather information and then make predictions based on what they have learned. Scientists can study lots of different things such as plants, animals, the human body, outer space, and more. They work in labs, out in nature, and even in space. Knowing the word scientist is important if you want to talk about people who work in fields like biology, chemistry, physics, astronomy, and many others.
