Fictional observations, not rock identification photographs. Sample A: grey, large visible grains. Sample B: grey, no grains visible with the hand lens. Record visible properties before guessing a rock's name. Use only adult-approved safe samples for any practical comparison: no hammering, dust-making, licking or acid tests.
