Mastering Core Concepts and Vocabulary

AP Environmental Science is rich with scientific terminology and complex ecological principles. Building a strong foundation in these areas is essential for understanding the exam material and answering questions accurately.

Active Reading and Note-Taking

Don’t just passively read your textbook. Engage with the material by highlighting key terms, summarizing paragraphs in your own words, and asking questions as you read. Cornell notes or concept mapping can be very effective for organizing information.

Focus on Key Terms

Create flashcards or a glossary for important vocabulary. Many APES questions rely on precise definitions and understanding the nuances of scientific terms. Ensure you know terms like “biodiversity,” “carrying capacity,” “biogeochemical cycles,” “tragedy of the commons,” and “anthropogenic.”

Understand Scientific Principles

Go beyond memorization. Strive to understand the underlying scientific principles. For example, how does the Second Law of Thermodynamics apply to energy flow in ecosystems? Why is genetic diversity important for population resilience? Understanding the “why” will help you apply concepts to new scenarios.

Utilize Visual Aids

Environmental science often involves understanding complex systems, cycles, and diagrams. Pay close attention to graphs, charts, maps, and ecological models presented in your textbook and review materials. Practice interpreting them, as they frequently appear on the exam.

Pro Tip: Connect Concepts Across Units

APES is an interdisciplinary course. Many environmental issues link multiple units. For instance, human population growth (Unit 2) can impact resource depletion (Unit 4), energy consumption (Unit 5), and pollution (Unit 6). Actively look for these connections to build a more holistic understanding.

Effective Study Strategies and Resources

The way you study is just as important as what you study. Employing a variety of strategies and using reliable resources will enhance your learning and retention.

Textbooks and Course Materials

Your primary textbook is a crucial resource. Make sure you understand its content thoroughly. Don’t forget your class notes and any handouts provided by your teacher, as they often highlight what’s most important for your specific course.

Review Books

Reputable AP Environmental Science review books (e.g., Princeton Review, Barron’s, Kaplan) can be invaluable. They often provide condensed summaries of key topics, practice quizzes, and full-length practice exams that mimic the actual AP test.

Online Resources

There are many excellent online resources available:

Collaborating with classmates can be highly beneficial. Discussing difficult concepts, quizzing each other, and working through practice problems together can deepen your understanding and expose you to different perspectives. Ensure your group stays focused and productive.

Practice Questions and Exams

This is arguably the most critical part of your preparation. Regularly work through practice questions. Start with topic-specific quizzes and gradually move to full-length practice exams. This helps you:

• Identify areas where you need more study.
• Become familiar with question formats and wording.
• Improve your time management skills.
• Build confidence.

The College Board provides released free-response questions from past exams. Practicing with these is an excellent way to prepare for the FRQ section.

Conquering the Multiple-Choice Section

The multiple-choice section accounts for half of your APES exam score. It tests your breadth of knowledge and your ability to apply concepts quickly. Strategic approaches can help you maximize your score.

Read Questions Carefully

Pay close attention to keywords in the question, such as “most likely,” “least likely,” “except,” “best describes.” These words can change the entire meaning of the question.

Analyze Data and Graphs

Many multiple-choice questions will include graphs, charts, or diagrams. Practice interpreting these visuals. Identify trends, outliers, and relationships before looking at the answer choices. Understand what the axes represent and the units used.

Eliminate Incorrect Answers

If you’re unsure of the correct answer, try to eliminate the obviously wrong choices. This increases your odds of guessing correctly if needed. Often, you can eliminate two or three options.

Manage Your Time

You’ll have approximately 1.5 minutes per question. Don’t get bogged down on any single question. If you’re stuck, make a mark next to it and come back later if time permits. It’s better to answer all questions than to leave some blank.

Familiarize Yourself with Common Question Types

Expect questions that require you to:

• Define scientific terms.
• Interpret data tables and graphs.
• Apply ecological principles to real-world scenarios.
• Identify causes and effects of environmental problems.
• Calculate simple ecological metrics (e.g., population growth rate, energy efficiency).

Excelling in the Free-Response Section

The free-response section (FRQ) tests your ability to think critically, synthesize information, and communicate your ideas clearly and scientifically. It’s where you demonstrate your deeper understanding.

Understand the Rubric

Each FRQ question has a specific scoring rubric. Familiarize yourself with how points are awarded. Typically, points are given for identifying key information, explaining processes, providing calculations, and making logical connections.

Structure Your Answers

For each FRQ, read the question carefully and identify exactly what it’s asking. Organize your thoughts before you start writing. Use clear paragraphs or bullet points as appropriate. Address each part of the question directly.

Show Your Work

For calculation questions, always show your work. Even if your final answer is incorrect, you can still earn partial credit for demonstrating the correct method. Include units in your calculations and final answer.

Use Scientific Terminology Correctly

Incorporate relevant scientific terms and concepts into your answers. This shows the grader you understand the subject matter. However, avoid using jargon unnecessarily; explain concepts clearly.

Practice Scientific Argumentation

Many FRQs require you to make a claim, provide evidence, and explain your reasoning (CER). Practice constructing these types of arguments. For example, if asked to propose a solution to an environmental problem, state your proposed solution (claim), explain why it would work (evidence/reasoning), and discuss potential drawbacks or alternatives.

Analyze Sample Responses

Reviewing high-scoring and low-scoring sample responses from past FRQs can be incredibly instructive. See what makes a good answer and what pitfalls to avoid. You can find these on AP Central.

Time Management for FRQs

You have 90 minutes for the FRQ section, which typically consists of two questions. One is often a document-based question (DBQ) or data-analysis question, and the other is a design-your-own-experiment question. Allocate your time wisely, aiming for roughly 45 minutes per question. It’s often recommended to tackle the question you feel more comfortable with first.

Key Environmental Science Concepts to Master

While the entire APES curriculum is important, certain core concepts are foundational and frequently tested. Deeply understanding these will give you a significant advantage.

Ecosystem Structure and Function

Understand trophic levels, energy flow (10% rule), biogeochemical cycles (carbon, nitrogen, phosphorus, water, sulfur), and the difference between producers, consumers, and decomposers. Know concepts like primary productivity (NPP, GPP) and limiting factors.

Population Dynamics

Master concepts like carrying capacity (K), exponential growth (r-selected species) vs. logistic growth (K-selected species), age structure diagrams, and factors affecting population size (birth rates, death rates, immigration, emigration).

Biodiversity and Its Importance

Understand the different types of biodiversity (genetic, species, ecosystem) and why biodiversity is crucial for ecosystem stability and resilience. Learn about threats to biodiversity, such as habitat fragmentation and invasive species.

Human Impact and Sustainability

This is a vast area. Focus on:

• Resource Use: Renewable vs. non-renewable resources, sustainable harvesting, deforestation, agriculture (monoculture vs. polyculture, GMOs, pesticides), and water management.
