Classifying Matter

Properties of Matter

by Lauren Olivares

Day 1- 7 Properties of Matter

Matter- the substance of which all things are made of​

Properties- the characteristics of a substance that help to clarify or identify it.

​​7 Properties of Matter:

• Conductor

• Insulator

• Magnetism

• Mass

• Density (sink or float)

• ​Physical State (solid, liquid, gas)

• ​Solubility

Metals and non metals can be sorted by the properties of conductors and insulators.

​

Day 2- Properties of Metals vs Nonmetals

Conductor- material that allows
thermal or electrical energy to pass through it.

Insulator- material that does not allow thermal or electrical energy to pass through it easily.

​

Metals and non metals can be sorted by the properties of conductors and insulators.

​

Day 3- Mass and Density

Conductor- material that allows
thermal or electrical energy to pass through it.

Insulator- material that does not allow thermal or electrical energy to pass through it easily.

​

​Mixtures

​Mixture- is made up of 2 or more substances that are combined and can be separated again.

​

Mixtures can be a simple mixture (can be separated again) or a solutions (solvent disolves into a solute).

​How to Classify Mixtures

​Mixtures can be classified and separated by:

• ​shape

• ​color

• ​size

• ​mass

• ​density

• ​magnetism

  ​solubility

Solution

• ​Solutions- is a mixture of two or more substances that are evenly distributed.

• ​Solutions are different than mixtures because they CAN'T be separated.

​Liquid & Solid Solutions

​Solutions are a mixture of two or more substances.

​

​Only Soluable substances can dissolve into a liquid to create a solutions.

​Liquid & Liquid Solutions

• ​Liquid and Liquid solutions combine a solvent and a solution.

• ​Solute- the substance that is dissolving.

• Solvent- substance in which the solute is dissolved.
