BECE 2017 Integrated Science Questions and Answers

The Basic Education Certificate Examination (BECE) is a critical assessment in Ghana, determining which students proceed to Senior High School. Each year, thousands of students prepare extensively, and one of the key ways they study is by reviewing past questions and answers. For those focusing on Integrated Science, reviewing the 2017 BECE questions and answers can offer an insightful perspective into the exam format, common topics, and the depth of understanding required. This article provides a detailed guide on the 2017 BECE Integrated Science questions and answers, helping students prepare efficiently and effectively.

Understanding the BECE Integrated Science Paper

Integrated Science in the BECE encompasses a wide range of topics, including biology, chemistry, physics, and environmental science. The questions are designed to test students’ knowledge, critical thinking, and ability to apply scientific concepts in real-life scenarios. The 2017 BECE Integrated Science paper consisted of two parts:

• Objective Questions: Multiple-choice questions covering various topics across the science curriculum.
• Theory Questions: Open-ended questions that require written explanations, calculations, or descriptions.

The 2017 questions focused on understanding scientific concepts, memorizing facts, and applying science to solve practical problems.

Key Topics in the 2017 BECE Integrated Science Questions

The BECE Integrated Science syllabus covers several broad areas. Here are the major topics frequently tested and which appeared prominently in the 2017 paper:

1. Living Organisms and Their Environment

This topic covers the characteristics of living things, classification, and interactions within ecosystems. In 2017, students were asked about animal and plant biology, with particular emphasis on the functions of various plant and animal cells, food chains, and food webs. For students, understanding the structure and function of cells, as well as basic ecology principles, is crucial.

2. Matter and Energy

Matter and energy, a core part of the science syllabus, includes topics like states of matter, heat, light, and electrical energy. The 2017 paper included questions on heat transfer, simple electrical circuits, and properties of materials. Students preparing for BECE Integrated Science should grasp concepts like conduction, convection, radiation, and basic electrical circuitry.

3. Human Biology and Health

Human biology questions are common in BECE Integrated Science. The 2017 questions tested knowledge of the human body systems (like the respiratory and circulatory systems), the functions of various organs, and health-related issues. Topics such as hygiene, disease prevention, and the importance of nutrition were also covered, making this an essential area of study for exam preparation.

4. Chemical Reactions and Compounds

Understanding chemical reactions is essential for BECE Integrated Science. In 2017, questions included topics on acids, bases, salts, and chemical reactions. For students preparing, learning to balance simple chemical equations and recognizing reaction types (like neutralization and combustion) can be highly beneficial.

5. Earth Science and the Solar System

Questions on Earth science and astronomy tested students’ knowledge of the planet’s structure, weather, climate, and the solar system. In 2017, students were asked to describe the Earth’s rotation, the water cycle, and the causes of day and night. This section requires an understanding of basic geology and astronomy concepts.

Sample 2017 BECE Integrated Science Questions and Answers

To give students an idea of what to expect, here are some sample questions from the 2017 BECE Integrated Science paper along with ideal responses. Practicing these questions can help students become familiar with the format and depth of answers expected.

Question 1: Describe the process of photosynthesis and explain its importance in the ecosystem.

Answer: Photosynthesis is the process by which green plants make their food using sunlight, carbon dioxide, and water. During photosynthesis, chlorophyll in the leaves captures sunlight, converting it into chemical energy, which helps to transform carbon dioxide and water into glucose and oxygen. Photosynthesis is crucial because it produces food for plants and oxygen, which is essential for the respiration of most living organisms.

Question 2: State and explain two functions of the human respiratory system.

Answer: The human respiratory system enables breathing, providing oxygen to the body and expelling carbon dioxide. The primary functions are:

• Oxygen Exchange: Inhaled air is rich in oxygen, which diffuses into the bloodstream through the lungs, supplying vital oxygen to body cells.
• Carbon Dioxide Removal: Carbon dioxide, a waste product of cellular respiration, is expelled from the bloodstream and released through exhalation, maintaining a balanced blood pH.

Question 3: Explain the difference between a series and a parallel electrical circuit.

Answer: In a series circuit, components are connected end-to-end so that there is only one path for current flow. If one component fails, the circuit is broken, and all devices stop working. In a parallel circuit, each component has its own separate path, so if one component fails, the others continue to function.

Tips for Answering BECE Integrated Science Questions

Answering BECE Integrated Science questions accurately requires a blend of knowledge and strategy. Here are some tips to help students approach the exam confidently:

• Study the Syllabus Thoroughly: Familiarize yourself with all topics on the BECE Integrated Science syllabus. Pay attention to areas emphasized in previous exams, like human biology, environmental science, and basic chemistry.
• Practice Past Questions: Going over past papers, especially from 2017, can give you a good feel for question patterns, frequently tested topics, and the level of detail required. Practicing with a timer can also help improve time management during the actual exam.
• Focus on Key Definitions and Diagrams: Integrated Science often includes questions that require definitions or labeled diagrams. Practice drawing and labeling diagrams like plant and animal cells, the human respiratory system, and simple circuits.
• Use Clear and Concise Language: When answering theory questions, aim for clarity. Use proper scientific terms, and ensure your answers are direct and to the point.
• Show Calculations When Necessary: For questions involving formulas or calculations, make sure to show all your steps clearly. This not only earns you partial credit but also demonstrates a logical problem-solving process.

Importance of Reviewing BECE Past Questions and Answers

Reviewing BECE past questions and answers, especially from years like 2017, is invaluable for a few reasons. First, it highlights recurring topics and themes, allowing students to focus on high-priority areas. Second, it builds familiarity with the exam structure, helping reduce anxiety. Finally, practicing with past questions allows students to assess their strengths and weaknesses, enabling targeted study.

Conclusion

The preparation for the BECE Integrated Science exam demands a commitment to the subject matter, an in-depth comprehension of scientific principles, and consistent practice with previously administered questions and answers. There is a wealth of information available to students who are interested in gaining a better understanding of the nature and level of questions that they may encounter on the 2017 BECE. Students have the ability to improve their chances of performing well on the day of the exam by concentrating on the fundamental subjects, practicing on a regular basis, and being familiar with the marking scheme. It is possible that the BECE Integrated Science paper will provide you with the opportunity to demonstrate your knowledge and establish a solid basis for your future academic endeavors if you prepare diligently and take a strategic approach to preparation.
