Are you curious about other planets? Did you ever wish you could explore them like the Mars rover in this picture? If so, then you’re thinking like a scientist. Scientists are curious about things in nature, and they do investigations to better understand them. They often use technology—from microscopes to Mars rovers—to extend their own senses so they can learn even more. In this unit, you’ll read about how scientists think and how they investigate and explore the natural world.
This unit introduces science and technology, and it outlines the scope of physical science. It describes careers in science and technology, as well as how scientists and engineers do their work. The unit also defines scientific theories and laws, and it gives an overview of basic science skills.
