Introduction

Rationale

The development of the Primary Science and Technology Curriculum for St. Kitts and Nevis is based on the philosophy that the students live in an integrated world. Their lives are impacted by scientific, technological, societal, and environmental factors all of which influence the kinds of challenges which students must face in school and in the wider community. It is hoped that exposure to the experiences provided by this program will help to prepare students to live meaningful lives and to be valuable assets to the communities in which they live. Teachers are encouraged to become familiar with the information in the following pages of this overview before embarking on their teaching assignments.

Aims

By actively participating in primary science and technology, the students will be enabled to:

  1. understand the nature of science and scientific knowledge;
  2. understand the nature of technology and its role in various aspects of life;
  3. understand and accurately apply appropriate science concepts, principles, laws and theories in interacting with society and the environment;
  4. use science processes in solving problems, making decisions, and furthering understanding of society and the environment;
  5. think in a logical way about everyday events, weigh alternatives and use technological processes to solve everyday problems;
  6. understand and appreciate the joint enterprise of science and technology and the interrelationships of these with each other and with other aspects of society and the environment;
  7. develop manipulative skills associated with science and technology;
  8. interact with the various aspects of society and the environment in a way that is consistent with values that underlie science;
  9. develop a richer, more satisfying, and exciting view of society and the environment, and continue to extend this interest and attitude throughout life.

Lessons
