  1. It is waterproof · Water runs off a rubber boot and cannot get in, so the boot is waterproof.
  2. True · A good group needs a reason, like 'these are all bendy.'
  3. See-through · Light passes through a glass bottle, so you can see what is inside.
  4. False · A good group needs a shared property, like these are all hard. No shared property means no real group.
  5. One is see-through, the other is not · Light passes through the glass jar. It does not pass through the wooden box.
  6. 2 · The dull bar shows 2 materials in that group.
  7. 3 · 7 take away 4 leaves 3. So 3 buttons are soft.
  8. Does it keep water out · Ria's goal names her property. She should check if each thing keeps water out.
  9. A stone is hard, not soft · A stone is hard. So the reason 'both soft' is not true for the whole group.
  10. The sponge · A sponge is soft, not hard. So it breaks the hard group.
