iAL Biology Topic 1C Diet CVD BMI Waist to Hip ratio (international A level) Pearson
The deck is a 29-slide, 16:9 PowerPoint teaching resource for Year 12 IAL Biology. It covers textbook lessons 1C.4 (Diet and Cardiovascular Health) and 1C.5 (Dietary Antioxidants and CVD). It uses a navy, teal and magenta colour scheme with plain text-first slides.
Structure
Slides 1-2: a title slide and learning objectives for both lessons.
Slides 3-17 (1C.4):
Obesity indicators: weight issues and BMI (formula, categories, a worked example, limitations) and waist-to-hip ratio.
Diet and blood lipids: tackling obesity, saturated fat as correlation versus cause, LDL and HDL, and the 2014 study of 72 papers.
Checkpoint: a questions slide at the end of the section.
Slides 18-22 (1C.5): fruit and vegetables and antioxidants, the vitamin C case study (the 1997 BMJ study against the 2016 metadata analysis), the DCPIP vitamin C practical (CP2), and a checkpoint slide.
Slides 23-29: seven exam-practice questions, each with a sample answer and mark points.
Topics: BMI calculation, limitations of BMI, fig C, LDL/HDL, saturated fat as correlation or cause, antioxidants, and the DCPIP practical.
Figures: each of the textbook graphs (fig A BMI chart, B, C, D, E, F, and fig A fruit and vegetables) has its own slide. They are images cropped from your PDF, each with notes on how to read it and an exam tip.
Teaching features
Highlighting: yellow highlighting marks what students should write down for the Unit 1 exam, such as formulas, thresholds, definitions, key evidence and practical method. A key at the bottom of each content slide explains this.
Speaker notes: the BMI worked-example slide and both checkpoint slides have short answer notes.
Additional past paper questions with mark schemes also added as a separate document.
