Description:

A mixture contains two or more substances that retain all their original properties and can be physically separated. Mixtures can be homogenous or heterogeneous.

The classroom resource provides a video that will describe the two types of mixtures. There is also a short test that can be used to assess students' understanding.

Description:

An element is as simple as it gets: substances that cannot be broken down into simpler substances. When elements get together and mix chemically, they make compounds, like water and salt!

The classroom resource provides a video that will describe the difference between elements and mixtures. There is also a short test that can be used to assess students' understanding.
