The document discusses the three main branches of science - Earth & Space Science, Physical Science, and Life Science. Earth & Space Science involves the study of Earth, its place in the universe, and objects beyond Earth. Physical Science includes the study of energy, motion, light, electricity, magnetism, and chemistry. Life Science is the study of living things like plants, animals, and microscopic organisms. While these branches are convenient categories, scientific questions often span multiple fields and they are not truly separate. The document also provides examples of how careers outside of science like chef, artist, sound technician, and firefighter rely on scientific knowledge within their work.

1. CAREERS IN SCIENCE Chapter 1, Section 4

2. Branches of Science The three main branches of science are Earth & Space Science Physical Science Life Science

3. EARTH & SPACE SCIENCE The study of Earth and it’s place in the universe Forces that have shaped Earth throughout history Earth’s ocean & weather Planets and stars beyond earth

4. PHYSICAL SCIENCE Includes the study of Energy Motion Sound Light Electricity Magnetism Chemistry

5. LIFE SCIENCE The study of living things including plants, animals and microscopic life forms

6. Separate, but Together Although it is convenient to think of science as divided into three branches, they are NOT really separate Most scientific questions span the different fields of science
