IB Biology Evolution and Classification Pub Quiz

Evolution and Classification 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: A3.1 Diversity of organisms, A3.2 Classification and cladistics, A4.1 Evolution and speciation, D4.1 Natural selection and D4.2 Stability and change.

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. Identical twins carry the same genes. Why are they never identical in every trait?
  2. A bodybuilder spends years building huge muscles. Why is this not evolution, even if his children grow up strong too?
  3. A finch's deeper beak, a guppy's bright spots, a bodybuilder's huge muscles, a moth's dark wings: which is the odd one out, and why?
  4. Why might clearing part of the Amazon rainforest reduce the rainfall over the rest of it?
  5. True or false: if two birds look very different, they must be different species. Explain.
  6. True or false: a single animal can evolve during its lifetime. Explain.
Answers
  1. The environment also shapes traits (and a few new mutations arise during life)
  2. The change is acquired, not inherited (it is not in his genes, so it cannot be passed on)
  3. The bodybuilder's muscles (acquired in life, not encoded in DNA, so not inherited)
  4. Less transpiration (less water vapour to form rain: a possible tipping point)
  5. False (males and females, like mallards, or young and adults can look very different)
  6. False (evolution is a change in a population's heritable characteristics, across generations)

Riddle me this

Course terms as riddles. Teams write what it is.

  1. I give every species two names: a capitalised genus, then a lowercase second word, as in Homo sapiens. What am I?
  2. We do different jobs, grasping, flying and swimming, but share one bone plan inherited from a common ancestor. What are we?
  3. I never plan ahead. I just let the better-suited survive and breed more, generation after generation. What am I?
  4. Pull me out and the whole arch of the community comes tumbling down. What am I?
  5. I'm a picture of a cell's chromosomes, cut out and lined up in pairs by length, banding and centromere position. What am I?
Answers
  1. Binomial system
  2. Homologous structures
  3. Natural selection
  4. A keystone species
  5. Karyogram

Quickfire

Short recall from the same topics.

  1. Differences among members of a species

  3. Two-part Latin naming, e.g. Homo sapiens
  4. Change in heritable traits of a population
  5. Farmers picking parents for desired traits
  6. Ancestor of kale, broccoli and sprouts
  7. Survival and breeding of the best adapted
  8. Change in a species over many generations
Answers
  1. Variation
  2. Biological species concept
  3. Binomial nomenclature
  4. Evolution
  5. Selective breeding
  6. Wild cabbage
  7. Natural selection
  8. Evolution

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.
