Open science is a way of doing research where scientists share their findings so others can use them to make new discoveries. Scientists might share the data they collected, the methods they used, the results they found, and the ideas they had, which can all be shared with people who weren't part of the original research. This helps other scientists learn from each other and build on existing scientific knowledge without repeating the same work over and over. It also helps people who don't have the same access to expensive equipment or resources to still participate in scientific research.
