Basic Science Exam Questions for JSS2 Second Term

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
Power is the rate at which work is done or energy is transferred.


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.
Work = Force × Distance
Work = 300 N × 10 m = 3000 J (Joules)

(b) Explain the energy transfer involved.
The students apply a force to move the car, transferring chemical energy from their muscles into mechanical energy, which is then used to move the car. The car gains kinetic energy as it moves.


3. If the kinetic energy of an aeroplane moving at a velocity of 100 m/s is 200 J, what is the mass of the aeroplane?

Using the formula:
K.E.= 1/2mv2
The mass of the aeroplane is 0.04 kg. 


3b. In effective communication skills, what does the acronym BRIEF mean?

BRIEF stands for:
B – Be clear and concise
R – Respect the listener’s time
I – Inform in an easy-to-understand way
E – Ensure engagement
F – Focus on key points


3c. Mention three conversation killers that must be avoided in communication.

  1. Interrupting the speaker
  2. Not paying attention or being distracted
  3. Using overly technical or complex language

4a. State 3 factors that influence an individual’s sense of self-worth.

  1. Self-esteem and confidence
  2. Social support and relationships
  3. Achievements and success

4b. In tabular form, state 2 differences between Verbal and Non-verbal communication.

Verbal Communication Non-verbal Communication
Involves words and language Involves body language, gestures, and facial expressions
Can be spoken or written Always non-spoken, often unconscious

4c. State 3 ways of improving communication.

  1. Active listening
  2. Clear and concise messaging
  3. Maintaining eye contact and positive body language

5a. State 5 importance of honest communication about pubertal concerns to responsible parents.

  1. It helps build trust between parents and children.
  2. It provides children with accurate information, reducing confusion.
  3. Ît allows parents to guide their children through physical and emotional changes.
  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.
