  • a. He could smell each bottle.
  • b. He did use odor as a substance property.
  • 11. What metal is more desirable for planes:
  • a. Aluminum is desirable for planes as it is strong and also light weight.
  • b. Lead is not desirable as it is very heavy.
  • 12. How could Sam separate rice from salt:
  • a. Sam could take the rice and salt mixture, and put it in water. The salt will dissolve in the water, and the rice will not. Then he could let the rice sink to the bottom and take the salt-water out. Sam could also use a strainer so the rice would stay in the strainer and the salt would fall through.
  • b. He uses two properties: (i) that salt is soluble in water and rice is not, and (ii) rice is ‘heavier’ and water, and will sink to the bottom. If he uses a strainer he is using the property of particle size.
