AEPA Middle Grades General Science Exam

A high score on the AEPA Middle Grades General Science Exam shows your ability to teach general science according to Arizona Academic Standards. Four areas are covered. First, Characteristics of Science (20%), which requires test takers to demonstrate a knowledge of scientific inquiry, principles, and procedures of scientific investigations. The next 25% of the test covers Life Science. The test taker must show competence in cell theory and the function and structure of organisms, as well as an understanding of communities and ecosystems. The Physical Science section of the AEPA Middle Grades General Science Exam is worth 30% and entails knowledge of properties of matter, reactions, force and mass, and characteristics of energy, light, sound, and electricity. The fourth section, Earth and Space Science (25%), covers the geologic history and composition of the Earth, the hydrosphere, climate, and atmosphere, along with the characteristics of the solar system and universe.
