Introduction to Basic Science as a School Subject

Basic Science is an introductory subject designed to help students develop an understanding of the natural world. It covers fundamental concepts in areas such as biology, chemistry, physics, and earth science. Through experiments, observations, and discussions, students learn about the environment, living organisms, matter, and energy. The subject encourages curiosity and critical thinking, laying the foundation for more advanced science studies in higher grades. Basic Science fosters an early interest in scientific inquiry and helps students appreciate the world around them.

The subject is offered by students in Primary school and Junior Secondary School under Basic Science and Technology.

So here you have the answers to the objective section of Agricultural Science Exam Questions for JSS2 second term. Use the comments section to let me know if you have any questions you would want me to clarify or discuss further.

Answers to Section B (Theory)

1a. Define the following

(i) Work
Work is done when a force acts on an object, and the object moves in the direction of the force.

(ii) Energy
Energy is the ability to do work or cause change.

(iii) Power

---

1b. Explain the meaning of:

(i) P.E.
P.E. stands for Potential Energy, which is the energy possessed by an object due to its position or state.

(ii) K.E.
K.E. stands for Kinetic Energy, which is the energy possessed by an object due to its motion.

---

2. A car of weight 300 N moved through a distance of 10 m when pushed by three students.

(a) Calculate the work done by the three students.

4. It helps in preventing risky behaviors through education.
5. It fosters a supportive environment for open discussion in the future.

---

5b. Mention the two types of Life Span Continuum and state two examples of each.

1. Physical Development: Growth, puberty.
2. Cognitive Development: Learning to speak, problem-solving skills.

---

5c. What is Communication?

Communication is the process of sharing information, ideas, or feelings between individuals through speaking, writing, or non-verbal means.

---

6a. State 3 statements of the kinetic theory.

1. All matter is made up of tiny particles (atoms or molecules).
2. These particles are in constant random motion.
3. The temperature of a substance is directly related to the average kinetic energy of its particles.

---

6b. List three phenomena which support the kinetic theory of matter.

1. Diffusion of gases
2. Expansion of substances when heated
3. Brownian motion

---

6c. Using the kinetic theory, explain why a solid has a definite shape and liquid has none.

In solids, particles are closely packed together and vibrate in place, maintaining a fixed structure, giving solids a definite shape. In liquids, particles are less tightly packed and can move past each other, allowing liquids to take the shape of their container but not maintaining a fixed shape.
