Scientific and engineering practices refer to the methods and techniques used by scientists and engineers to explore, understand, and solve problems. These practices include making observations, asking questions, developing hypotheses, conducting experiments, and analyzing data. They help ensure that findings are reliable and can be replicated by others. In engineering, practices also involve designing, building, and testing prototypes to create solutions for real-world challenges. This process often includes collaboration, communication, and iterative testing to improve designs. Both fields emphasize critical thinking and the application of knowledge to advance technology and enhance our understanding of the natural world.
