D3.3 Homeostasis: grass skirts

23 quick questions on homeostasis, 16 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.

The questions on this sheet

The checker’s key, with every answer, prints with the sheets.
  1. Keeping the internal environment steady
  2. Response that reverses a change
  3. Hormone that lowers blood glucose
  4. Pancreas hormone that raises blood sugar
  5. Storage polysaccharide in liver and muscle
  6. Brain area that monitors body temperature
  7. Muscle contractions that generate heat
  8. Glands releasing salty fluid onto the skin
  9. Removal of waste made by metabolism
  10. Pituitary signal that inserts aquaporins
  11. Response that amplifies a change
  12. Target value the body keeps a variable at
  13. Immune destruction of insulin-making cells
  14. Body cells stop responding to insulin
  15. Widening of skin arterioles to lose heat
  16. Narrowing of skin arterioles to keep heat
  17. Hormone that raises basal metabolic rate
  18. Control of water balance in body fluids
  19. Capillary knot where blood is filtered
  20. Where all glucose returns to the blood
  21. Builds a salt gradient in the medulla
  22. Final tube where urine is concentrated
  23. Heat-making store with many mitochondria
