Junior Secondary School (JSS) 3 students in Nigeria are expected to have a comprehensive understanding of Basic Science as part of their curriculum. This subject encompasses a wide range of scientific concepts, including biology, chemistry, physics, and environmental science. To aid students in their studies and preparation for exams, this article provides a compilation of past questions and answers, along with frequently asked questions (FAQs) regarding Basic Science in JSS 3.
Importance of Past Questions
Studying past questions is crucial for students as it helps them:
- Familiarize themselves with the exam format and types of questions asked.
- Identify key topics and concepts that are frequently tested.
- Develop effective study strategies by analyzing their performance on these questions.
Sample Past Questions and Answers
Question 1:
What is the process by which plants prepare their own food?
Answer: The process by which plants prepare their own food is called photosynthesis. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. This process mainly occurs in the leaves, where chlorophyll captures light energy.
Question 2:
List three states of matter and give one example of each.
Answer: The three states of matter are:
- Solid – Example: Ice
- Liquid – Example: Water
- Gas – Example: Oxygen
Question 3:
What is the function of the human respiratory system?
Answer: The function of the human respiratory system is to facilitate gas exchange. It allows oxygen from the air to enter the bloodstream and carbon dioxide, a waste product of metabolism, to be expelled from the body.
Question 4:
Define an ecosystem and provide two examples.
Answer: An ecosystem is a community of living organisms (plants, animals, and microorganisms) interacting with their physical environment (soil, water, and air). Examples of ecosystems include:
- Forest Ecosystem
- Aquatic Ecosystem
Question 5:
What is the difference between renewable and non-renewable resources? Provide one example of each.
Answer: Renewable resources are natural resources that can be replenished naturally over time, such as solar energy or wind energy. In contrast, non-renewable resources are resources that do not replenish at a sustainable rate, such as fossil fuels (coal, oil, and natural gas).
