INSTRUCTIONAL PROCEDURES

PERIOD 1-5

PRESENTATION

STEP 1: INTRODUCTION

  • The teacher introduces nuclear reactions, focusing on fission and fusion.
  • Students discuss their understanding of nuclear energy.

STEP 2: EXPLANATION

  • The teacher explains nuclear fission, where the nucleus of an atom splits into two smaller nuclei, releasing energy.
  • Explain nuclear fusion, where two smaller nuclei combine to form a larger one, also releasing energy.
  • The teacher explains how nuclear energy is harnessed for power.

STEP 3: DEMONSTRATION

  • Demonstrate nuclear fission and fusion with visual aids or a video.
  • Students are asked to draw a simple diagram of the fission and fusion processes.

STEP 4: APPLICATIONS OF RADIOACTIVITY

  • The teacher leads a discussion on how radioactivity is used in medicine (e.g., cancer treatment), agriculture (e.g., pest control), and industry (e.g., radiography).

STEP 5: CASE STUDY: NIGERIA'S NUCLEAR ENERGY PROGRAM

  • The teacher presents a case study on Nigeria's nuclear energy program, including its goals, achievements, and challenges.
  • Discuss the potential benefits and risks of nuclear energy for Nigeria.

EVALUATION

  1. Describe nuclear fission and fusion.
  2. How is nuclear energy produced, and what are its uses?
  3. What are the applications of radioactivity in industry and medicine?

CLASSWORK:

  • Write a brief report on Nigeria's nuclear energy program, including the benefits and challenges.

CONCLUSION

  • The teacher will summarize the key points and provide feedback on classwork.
  • Students are encouraged to consider the implications of nuclear energy in the future.
