The Natural Science portion of the Licensure Examination for Teachers (LET) measures your understanding of the basic concepts and principles of the physical and biological sciences. It evaluates your ability to explain scientific phenomena, apply reasoning to real-life situations, and demonstrate an appreciation of how science impacts daily life and the environment.
This Natural Science Practice Test is designed to help you review essential topics in science and improve your problem-solving and analytical skills. It consists of 50 random multiple-choice questions covering various branches of science commonly included in the LET.
After answering each question, the correct answer will be marked in green, while incorrect ones will appear in red. Read each question carefully and choose the best answer from the given options.

Tips for Answering Science Questions
1. Understand concepts, don’t just memorize facts.
Science questions often test your comprehension and ability to apply ideas, not just recall definitions.
2. Read carefully and analyze.
Some items may appear similar, but small details—like units, quantities, or terms—can change the correct answer.
3. Remember key formulas and relationships.
Especially for Physics and Chemistry, recall important formulas and the logic behind them.
4. Visualize and connect.
For Earth Science and Biology, try to imagine the process or structure being described—it helps solidify understanding.
5. Practice regularly.
Answering many questions over time will help you recognize question patterns and improve accuracy and speed.
Final Reminders
The Natural Science section of the LET evaluates both your scientific knowledge and your ability to think critically. Always read each question carefully, reason through your answers, and rely on what you’ve studied.
