Oi is ​ (a)   than water

• less dense
• more dense

How can you classify a copper penny, iron filing, and an aluminum foil?

• Use a magnet to classify them from other objects.

• It is soluble in water. By evaporating water, you can then separate these items.

• It conducts thermal and electrical energy

  It is not soluble in water

• Use water so you can test their density by forming layers then you can filter them out with coffee filters.

Which object can:

-conduct electrical energy

-conduct thermal energy

-solid

-doesn't dissolve

• oil

• metal

• cork

• toothpick

What does have these object have in common?

Paper, rock, sand, iron filings, pencil eraser

• They are all magnetic and are solid state

• They are thermal insulators and are solid state

• They are not soluble and they are all solid state

The word SINK AND FLOAT is about

• mass

• density

• conductivity

• solubility

Oil, wood, feather are all ​ (a)   than water

• less dense
• more dense
