IB Biology Human Physiology Pub Quiz

Human Physiology as a pub quiz for your class: review rounds on these subtopics, mixed with pure-fun rounds so it feels like a night out and not another test. Opens at SL; switch to HL in the builder to add the higher level cards.

Teacher pages are the quizmaster script and tally sheet. Student pages are the team answer sheet, handout and picture sheet. Both open ready to print, on A4 or US Letter.

What it covers

IB Biology at SL, with HL cards when you switch the level: B3.1 Gas exchange, B3.2 Transport, B3.3 Muscle and motility, C2.1 Chemical signalling, C2.2 Neural signalling, C3.1 Integration of body systems, C3.2 Defence against disease and D3.3 Homeostasis.

The running order

nine rounds and a handout of riddles. Review rounds are drawn from these topics each time you open the quiz, so two classes never get the same paper, and every review round can be redrawn in a click.

  1. Riddle me this review
    Course terms as riddles: "I have a head that loves water and two tails that hate it…" Teams write what it is.
  2. Close-up fun
    A tiny zoomed-in patch. What's the full picture?
  3. Fact or fiction fun
    Myths and true-but-weird facts. Teams write Fact or Fiction.
  4. Think it through review
    Scenarios, odd ones out, true or false and why, puzzles: questions to reason through. Give teams a little longer.
  5. Films in science-speak fun
    A film plot, described like a research abstract. Name the film.
  6. Who am I? Scientists fun
    Three clues, hardest first. 3 points after clue 1, 2 after clue 2, 1 after clue 3.
  7. Missing vowels: course terms review
    Your key terms with the vowels taken out.
  8. Funny animal noises fun
    YouTube clips of animals making ridiculous noises. Screen off, listen, guess, then watch the reveal.
  9. Closest wins fun
    Estimation questions. Nearest team wins the point. Doubles as the tiebreaker.

A taste of the questions

Think it through

Scenarios, odd ones out and true or false and why, from IB Biology.

  1. A flatworm has no lungs or gills and gets all its oxygen through its skin. Why could a mouse never do that?
  2. Capillaries in the kidney and the small intestine have tiny pores (fenestrations) in their walls. Why there?
  3. Why is the inside of a resting neuron negative compared with the outside?
  4. Baroreceptors in the aorta detect a sudden rise in blood pressure. How does the medulla change what the heart is doing?
  5. Why are patients with large burns at very high risk of infection?
  6. True or false: the body uses positive feedback to bring its temperature back to normal.
Answers
  1. It is too bulky (its SA:V is too low and the distance to its centre too great for diffusion alone)
  2. Exchange there must be especially rapid (the pores let fluid and solutes through fast)
  3. The pump moves 3 Na⁺ out for every 2 K⁺ in, and K⁺ leaks back out
  4. Slows the heart rate (and reduces stroke volume) by nerve impulses
  5. The skin, the body's barrier against pathogens, has been destroyed
  6. False (negative feedback reverses the change, back towards the set point)

Riddle me this

Course terms as riddles. Teams write what it is.

  1. I'm one of about 480 million tiny air sacs. Spread my family flat and we'd cover about 70 m². What am I?
  2. I'm only one cell thick, and so narrow that red cells pass through me in single file. What am I?
  3. I'm a single long fibre that can stretch from your spine to your toe, carrying impulses away from the cell body. What am I?
  4. I sit at the back of your brain, keeping you balanced and making sure your muscles work smoothly together. What am I?
  5. I'm a white blood cell that eats first and asks no questions, engulfing any invader I find. What am I?
Answers
  1. Alveolus
  2. Capillary
  3. Axon
  4. Cerebellum
  5. Phagocyte

Quickfire

Short recall from the same topics.

  1. Air sac at the end of a bronchiole
  2. Narrow branching airway ending in alveoli
  3. Coating that stops alveoli collapsing
  4. Narrow vessel with a wall one cell thick
  5. Pore in a capillary wall for fast exchange
  6. Thick-walled vessel leaving the heart
  7. Part of a neuron holding the nucleus
  8. Long fibre carrying impulses to terminals
Answers
  1. Alveolus
  2. Bronchiole
  3. Surfactant
  4. Capillary
  5. Fenestration
  6. Artery
  7. Cell body
  8. Axon

How it runs

  1. Open it in the builder. The running order loads ready to go. Swap, add or drop rounds, or draw a round's questions again.
  2. Present it or print it. Present puts each round on the projector in 16:9 with quizmaster notes. Print gives the script, team answer sheets, a picture sheet and a tally sheet on A4 or US Letter, with no projector needed.
  3. Score it. Teams swap sheets, mark, and each plays one joker to double a round. The scores page reveals the leaderboard from last place up.
