Responses and energy flow: grass skirts

21 quick questions on AP Biology topics 8.1 Responses to the Environment and 8.2 Energy Flow Through Ecosystems, 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. Chemical message within a species
  2. Inborn response needing no practice
  3. Response shaped by experience
  4. Seasonal long-distance movement

  6. Body heat mostly from the surroundings
  7. Makes its own food from light or chemicals
  8. Eats producers directly
  9. Recycles nutrients from dead matter
  10. Feeding position in a food chain
  11. Interlinked feeding relationships
  12. Diagram of joules per feeding level
  13. Movement toward or away from a stimulus
  14. Response to day length, e.g. flowering
  15. Acting together to raise group survival
  16. Bee signal showing food location
  17. Energy an organism uses per unit time
  18. Rough share of energy passed up a level
  19. Total rate of photosynthesis in an area
