Changes in the Properties of Materials

The properties of materials may change due to extreme heat or cold.

​Heating up hard or brittle materials makes them easier to manipulate (glass or metal)

​Extreme cold may also affect the properties of materials, ex: Liquid water may expand while freezing.

​

​Extreme Temperature

​

Mixture - a combination of two or more materials.

Heterogeneous mixture - you can still identify the components.

​

​

​Mixing with Other Materials

​

Homogeneous mixture - you cannot see the different components anymore.

​

Mixing with Other Materials

​

Solid mixtures can be separated manually or by sifting.

Liquids can be separated through evaporating.​

​

​Separating Mixtures

When two liquids mix, it may be hard to tell them apart. They are miscible.

Oil and water have different densities and cannot mix. They are immiscible.​
