Introduction to Basic Science as a School Subject

Before we venture into Past Basic Science Exam Questions for JSS2 First term, here’s a brief introduction to the subject:

Basic Science is a subject taught in junior secondary schools that introduces students to the study of nature, the environment, and the world around them. It combines simple concepts from Physics, Chemistry, Biology, and Earth Science to build a foundation for scientific knowledge. The subject helps students to develop curiosity, observation skills, and problem-solving abilities. Basic Science also prepares students for senior secondary science subjects and encourages them to apply scientific ideas to everyday life.

The subject is offered by students in Primary school and Secondary School as Basic Science.
