Target Misconceptions Solved:

This worksheet directly addresses common student errors in GCSE Science exams, including:

• Forgetting to square the distance before taking the reciprocal.
• Confusing "proportional to" with "equal to".
• Assuming that doubling distance halves light intensity (rather than reducing it to a quarter).
• Failing to connect light intensity calculations to photosynthesis rates.

Curriculum Alignment:

• Exam Board: AQA GCSE Combined Science (Trilogy / Synergy) & AQA GCSE Biology (Triple Science)
• Specification Topic: 4.4 Bioenergetics (Photosynthesis Rate & Light Intensity)
• Tier: Suitable for Foundation and Higher Tiers

Whether assigned as classwork, homework, revision practice, or cover work, this GCSE science worksheet gives students the structured practice needed to secure top calculation marks in their biology exams.
