What it covers

IB Biology at SL, with HL cards when you switch the level: D3.1 Reproduction.

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. Aphids reproduce asexually all summer, then switch to sexual reproduction in autumn. Why switch as conditions change?
  2. A strawberry plant thriving in a sunny bed spreads by runners instead of seeds. What is the advantage?
  3. Why are sperm so much smaller than eggs?
  4. Your mitochondria all came from your mother, none from your father. Why?
  5. In the second half of the menstrual cycle, high progesterone keeps FSH and LH low. What type of feedback is this, and what does it stop?
  6. Just before ovulation, rising oestradiol makes the pituitary release more LH, not less. What type of feedback is this?
Answers
  1. Variation (new allele combinations help offspring adapt to a changing environment)
  2. Identical offspring (just as well adapted to that environment as the parent)
  3. Sperm must travel to the egg (so carry little food; the egg holds the food reserves)
  4. The sperm's mitochondria are destroyed after it enters the egg (along with its tail)
  5. Negative feedback (stops new follicles developing)
  6. Positive feedback (the LH surge it causes triggers ovulation)

Riddle me this

Course terms as riddles. Teams write what it is.

  1. I'm the yellow body left behind when an egg escapes its follicle, and I pump out progesterone. What am I?
  2. LH surges, a follicle bursts, and I'm the moment the egg is set free. What am I?
  3. A bee does me by accident, carrying dusty grains from an anther to a stigma. What am I?
  4. I thicken every month in case a guest arrives, and I'm shed if no embryo moves in. What am I?
  5. I'm a plant's genetic trick for refusing pollen from its own flowers, to dodge inbreeding. What am I?
Answers
  1. The corpus luteum
  2. Ovulation
  3. Pollination
  4. The endometrium

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.
