1. Section 1

2. A. Science is a system of knowledge and the methods you use to find that knowledge. B. Technology is the use of knowledge to solve practical problems. a. The goal of science is to expand knowledge to solve practical problems. b. The goal of technology is to apply that knowledge.

3. C. Science and Technology are interdependent. a. What does that mean? 1. It means advances in one lead to advances in the other. Ex. Advances in energy will lead to advances in items that use energy. Such as gasoline to ethanol. D. The study of science is broken up into two main branches. Social Science and Natural Science. a. Natural science is broken up into three different branches. Physical science, Earth and Space Science, and Life Science.

4. E. The two main branches of physical science are chemistry and physics. a. Chemistry is the study of the composition, structure, properties, and reactions of matter. b. Physics is the study of matter and energy and the interactions between the two through forces and motion. c. The application of physics and chemistry to the study of Earth is called Earth Science.

5. F. Other branches include Geology (the study of the origin, history, and structure of Earth), Astronomy (the study of the universe beyond Earth), Biology (the study of living things). E. Just because Science is broken up into different parts doesn’t mean that each part is limited to its own branch. Many branches of science overlap one another. Such as biophysics. F. What are four big ideas of science? A) Space and Time C) Forces and Motion B) Matter and Change D) Energy
