Strategies for Human Body Temperature Regulation: Key Concepts and Methods

This guide explores the adaptations that help humans maintain a consistent body temperature. Key points include responses to heat such as sweating and increased thirst, and reactions to cold like shivering and hair standing on end. It also discusses blood flow adjustments and insulation as crucial mechanisms. The guide highlights a method for answering related exam questions: brainstorming bullet points, logically sequencing ideas, and elaborating on them through cause-and-effect sentences. Additional practice questions on carbon in the atmosphere, reflex arcs, and medical trials provide comprehensive review opportunities.

Presentation Transcript

  1. 6 Mark Questions Examples from AQA B1

  2. Body temperature • What adaptations help a human to maintain a consistent body temperature?

  3. Method • First, bullet point a few ideas or key words relevant to the question. • Next, put them into a logical sequence by writing a number next to each one. You may wish to add or remove points. • Turn each one into a sentence, linking them by describing causes and effects (so, which means that, and then…)

  4. Body temperature • Hot sweat thirsty • Cold shiver hairs on end Blood flow?

  5. Body temperature • Hot sweat 1 thirsty 2 • Cold shiver 4 muscles/respiration hairs on end 5 insulation Blood flow? 3, 6

  6. Example Questions • Explain how human actions have increased the amount of carbon in the atmosphere. • Describe the stages of a reflex arc when a person touches a hot plate. • How are medical trials tested before widespread use and why?

  7. Using the method • For your question, write the bullet point ideas and sequence them. • Compare your order with your partner; would you agree or disagree? • What do you add when you take a moment to think? What might you remove? • How would you link these ideas together in sentences?

  8. Carbon in the Atmosphere • Burning • Photosynthesis • Respiration • Fossil fuels • Plants • Animals • Decomposition

  9. Reflex Arc • Stimulus • Receptor • Sensory neurone • Relay neurone NO BRAIN • Motor neurone • Effector (muscle) • Response

  10. Medical Trials • Reduce deaths/improve health • Double blind/randomized • Animals/cells • Healthy people • Ill people

  11. Changes • Each of these sets of bullet points is incomplete. How do they compare to your thinking? • Write up possible answers in sentences then discuss these with your partner. Do you agree on a predicted mark? • Use markschemes to check your score. Are you making predictable or repeated mistakes?
