Science is all about figuring out how the world works. Scientists study things they don't understand, like why the sky is blue or why we get sick when we're sick. They collect information and use it to come up with explanations and make predictions on how things work and how they might be able to do it better in the future. It's a lot like trying to solve a big puzzle. Most of the time, science is done in labs and experiments, but some scientists study things like plants and animals in nature as well. Science can also be used to help make our lives better, like when we use it to make medicine to help us get better when we're sick.
