13. Answers will vary but should include at least three (3) properties that involve other senses or measurable values. For example, texture, mass, hardness, flexibility, or conductivity.

(4 marks — 1 mark per point (up to 3), 1 mark for proper sentence structure)

15. Look for the following explanations and possible examples.

• A solid has particles so closely packed together that they do not move much. This makes a solid keep its shape (e.g., ice).

• A liquid has particles that are more loosely packed than a solid and move around freely. This makes a liquid able to take the shape of its container (e.g., water in a fish tank).

• A gas has particles that are very loosely packed and bouncing off each other. This makes a gas expand to fill its container completely (e.g., water vapour coming from a kettle).
