Teacher answer key — 3 questions

Model responses identify the essential ideas. Accept scientifically correct alternatives that address the question; wording need not match exactly.

  1. Observed positions of points of light changed relative to Jupiter; the interpretation was that these were orbiting moons.
  2. 5.5 mL, equivalent to 5.5 cm³ under the submersion assumptions.
  3. Unknown microbial growth creates avoidable exposure risks. Use the supplied account or verified images; no mould-growing or bacterial culture is requested.
