A focused three-component revision and exam practice pack for SP6k, covering the complete Edexcel Separate Science Physics specification for evaluating nuclear power and identifying nuclear reactions as energy sources (P6.36P, P6.37P).

Topic Mastery Sheet covers the three types of nuclear energy source (radioactive decay, fission, fusion) with their applications; a balanced advantages and disadvantages table for nuclear power versus fossil fuels (advantages: no COâ‚‚ during operation, high energy density, reliable; disadvantages: radioactive waste lasting thousands of years, accident risk, decommissioning cost, public perception, high capital cost); the distinction between fission (large nucleus splits) and fusion (small nuclei join); and the products of uranium-235 fission (two radioactive daughter nuclei, two or more neutrons, release of energy). The evaluation is presented as a genuine balance rather than a one-sided account, supporting the six-mark style evaluation questions in the specification.

Student Exam Practice Sheet includes a two-mark nuclear power advantage/disadvantage question; a two-mark fission vs fusion distinction question; and a three-mark fission products description question (matching the mark scheme wording: two daughter nuclei; two or more neutrons; energy release). Question format matches the Edexcel test style.

Teacher Answer Key provides a complete mark scheme noting that the fission products answer requires all three distinct points (daughter nuclei, neutrons, energy) and that the daughter nuclei being radioactive is an additional specification point (P6.42P).
