A Pennsylvania middle grades science guide for the ETS selected-response format, calculator rules, scientific inquiry, physical science, life science, and Earth and space science.
Praxis 5159 preparation should build broad science command across inquiry and methodology, physical science, life science, Earth and space science, environmental issues, technology impacts, and calculator-supported problem solving.
Use these official structure points to organize Pennsylvania Grades 4-8 Science study.
ETS lists Praxis 5159 as a selected-response exam.
The exam is 1 hour and 30 minutes.
The current ETS study companion lists 90 questions.
Physical Sciences is the largest category at 25 questions, or 28%.
Basic Principles and Processes covers inquiry, methodology, techniques, history, scientific tools, safety, data, and measurement. This category supports every content area, so it should be reviewed early.
Physical Sciences is the largest category. Candidates should review matter, atomic structure, chemical reactions, energy, forces, motion, electricity, magnetism, waves, light, and heat with calculation practice where useful.
Life Sciences and Earth and Space Sciences are each 24% of the exam. Study cells, genetics, evolution, ecology, geology, weather, climate, astronomy, and human impacts with diagrams, cycles, and cause-effect explanations.
