A3.1 Diversity of organisms: grass skirts

17 quick questions on diversity of organisms, 12 of them at standard level, 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.
