Unit 8, Ecology: grass skirts

48 quick questions across the whole of Unit 8 (a fresh 30 on each print), 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. Movement toward or away from a stimulus
  2. Undirected change in movement rate
  3. Chemical message within a species
  4. Inborn response needing no practice
  5. Response shaped by experience
  6. Seasonal long-distance movement
  7. Response to day length, e.g. flowering
  8. Acting together to raise group survival
  9. Bee signal showing food location
  10. Warms itself with metabolic heat
