What it covers

IB Biology at SL, with HL cards when you switch the level: C3.2 Defence against disease.

The running order

nine rounds and a handout of riddles. Review rounds are drawn from this topic 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. Why are patients with large burns at very high risk of infection?
  2. A patient with very few platelets bleeds for a long time after a small cut. Why?
  3. Fibrinogen circulates in your blood all the time. Why doesn't your blood normally clot inside your vessels?
  4. True or false, and why? Blood clotting matters only because it stops blood loss.
  5. Pus in an infected wound is mostly dead white blood cells. Why do so many gather there?
  6. I'll swallow any bacterium I meet, the first time or the tenth, and I never get any better at it. Which immune system am I part of, and why?
Answers
  1. The skin, the body's barrier against pathogens, has been destroyed
  2. Platelets release the clotting factors that start the clotting cascade
  3. Fibrinogen is soluble; it becomes insoluble fibrin only when thrombin is activated at a cut
  4. False (the clot also seals the wound against pathogens)
  5. Phagocytes move to the infection to engulf and digest pathogens, and many die
  6. The innate system: it responds to broad categories of pathogen and does not change

Riddle me this

Course terms as riddles. Teams write what it is.

  1. I'm a white blood cell that eats first and asks no questions, engulfing any invader I find. What am I?
  2. I'm a Y-shaped protein made to fit one invader's marker exactly. What am I?
  3. I'm the marker on a pathogen's surface that tells your immune system it's foreign. What am I?
  4. I'm the tangled mesh that traps red blood cells to seal a cut. I was soluble until thrombin got to me. What am I?
  5. I hang around for years after an infection, ready to make antibodies fast if it ever comes back. What am I?
Answers
  1. Phagocyte
  2. Antibody
  3. Antigen
  4. Fibrin
  5. Memory cell

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.
