Question 1

Classify: gritty surface; 2.35 g; sample 2; four visible bands.

Question 2

Add suitable units to a measured water volume of 50 and a duration of 30.

Question 3

Rewrite “The flower opened a bit.”

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. Gritty is qualitative; mass and band count are quantitative; sample number is an ID.
  2. 50 mL and 30 s are suitable examples. Accept other explicit units if the context remains coherent.
  3. For example, the widest petal-to-petal span increased from 20 mm to 31 mm over 2 h; keep the measurement rule fixed.
