The Branches of Science

What is Science?

 Science- The system of acquiring knowledge through systematic experimentation and methodology. The search for truth and knowledge.

3 Main Branches of Science Life Physical Earth/Space

Types of College Degrees

     All Science careers require at least a high school diploma. Most careers require a 4 year college degree and beyond.

Associate- 2 year technical degree awarded by community or Junior colleges. Can be transferred to a 4 year college. Bachelor- A 4 year undergraduate degree from a college or university.

Master’s- An academic degree lasting 1-3 years. A thesis (big project) and research must be completed Doctorate- The highest education degree possible. Upon completion students are awarded a Phd and are called doctors (not just medicine).

Earth/Space Science Career Spotlight


A person who studies volcanoes If you enjoy walking around next molten lava and traveling around the world than this is for you!. Volcanology Is the study of volcanoes , lava , magma and related geological phenomena. A volcanologist is a person who studies in this field. The term


is derived from the Latin word


, the Roman god of fire.

Volcanologists frequently visit volcanoes, especially active ones, to observe volcanic eruptions , collect eruptive products including tephra , rock and lava samples. One major focus of enquiry is the prediction of eruptions; there is currently no accurate way to do this, but predicting eruptions, like predicting earthquakes, could save a lot of lives. A minimum of a bachelor’s degree is required and to do research a Master’s degree and Phd are required.

Earth/Space Science Career Spotlight

• Tornado Chaser Tornado chasers can be found throughout the U.S. especially in the spring. Tornado chasers identify and measure where conditions exist where tornados exist. When tornados form chasers try to get as close as they can to measure the meteorological conditions. If you like chasing around possible tornados with winds over 200 mph this is a career for you. Education requirements include a 4 year college degree in meteorology and a master’s degree.
