Praxis II Chemistry Physics and General Science Exam by ETS

The Chemistry, Physics and General Science exam of the PRAXIS II Series are taken by future junior and senior high school teachers who are interested in teaching chemistry, physics or general science. While writing for this examination, individuals must have a bachelor's degree or be approaching towards graduation from a bachelor's degree program. The exam is of two hours and 120 multiple choice questions will be there, divided among five categories as quoted below:

  • 36 questions on Chemistry.
  • 36 questions on Physics.
  • 24 questions on Major Ideas of Chemistry and Physics.
  • 12 questions on Earth and Space Science.
  • 12 questions on Life Science.

In the category of Chemistry, questions will evaluate your knowledge of kinetics, the chemistry of acid and bases, thermodynamics, electrochemistry, biochemistry and organic and inorganic chemistry. Oxidation, solutions, formulas, the mole, periodicity and lab safety regarding chemistry is also included here.

In the category of physics, questions will include mechanics, consists of fluid, kinematics and dynamics. Magnetism and electricity which consists of fields, forces, and laws of magnetism and electricity; conductors; and circuitry will also be there. And optics and waves, modern physics and the concerns of physics as related to the environment will be included in this category.

In the category of Major Ideas of Chemistry and Physics, questions will be on the scientific methods, the gathering and interpreting of data, as well as subjects such as radioactivity and thermodynamics and features of atoms. Properties and theories such as those associated to molecular kinetics, matter, and physical and chemical transformations are also included in this category.

In the category of Earth and Space Science, questions will cover the subject of astronomy, geology, meteorology, and oceanography as well as concerns of the environment related to these sciences. Questions on astronomy will cover the solar system, galaxies, and the universe, and the investigation of space. Geology questions will be based on rocks and minerals, weathering and erosion, topographic geology and historical geology. The meteorology questions cover the fundamentals like climate and weather systems and atmosphere. Oceanography consists of biological, geological, chemical and physical features of water.

In the category of Life Science, questions pertaining to topics of cells, ecology and organisms. In addition, the questions on the relationship of life science to the environment may also be there in the exam.

It must be noted that calculators are not allowed in this exam.
