Hardy-Weinberg and evidence for evolution: grass skirts

14 quick questions on AP Biology topics 7.5 Hardy-Weinberg Equilibrium, 7.6 Evidence of Evolution, 7.7 Common Ancestry and 7.8 Continuing Evolution, each answered in a word or two. Print a sheet for each team, a key for the checker and a tick sheet, then tape the sheets to the board and race.

How it runs

  1. SnipA runner cuts one strip off the bottom of their team’s sheet.
  2. Answer as a pairBack at the table, they write the answer on the strip. No books.
  3. Get it checkedThe checker reads it against the key: you, or a student holding it.
  4. Back for the nextA tick earns the next strip. Wrong? Back to the table to try again.

The questions on this sheet

The checker’s key, with every answer, prints with the sheets.
  1. Dated remains in rock layers
  2. Human arm and whale flipper bones
  3. Reduced remnant, e.g. whale hip bones
  4. Species from which two lineages descend
  5. Trait spreading in bacteria after drug use
  6. No evolution: allele frequencies constant
  7. Partners chosen with no preference
  8. Expected share of heterozygotes
  9. Aging fossils with isotope half-lives
  10. Intermediate such as Tiktaalik
  11. Bird and insect wings, for example
  12. Same triplet meanings in nearly all life
  13. Insects no longer killed by DDT spray
  14. DNA little changed across many species
