Students investigated properties of four objects using a hand lens, magnet, and a beaker container water. According to the chart, which statement could be used to classify these objects into two different groups?

• Density can be used to separate objects that sink and float.
• Magnetism can be used to separate objects into a group that is attracted and a group that is not.
• Solubility can be used to separate into a group that dissolves and a group that do not.
• Physical state can be used to separate in solids and not solids.

A student classifies the objects shown based on their physical properties. Which property can NOT be used to classify these objects into more than one group?

• magnetism
• mass
• electric conductivity
• solubility in water
