Particle Model of Solids, Liquids, and Gases
Display the arrangement of molecules in solids, liquids, and gases. Demonstrate how the addition of heat energy results in greater molecular motion and therefore a change of phase. Give examples of heat conductors and insulators, and...

Density of Solids and Liquids
Middle schoolers calculate the density of regular and irregular solids and liquids. They relate the term dense to science as well as its literal meaning that society uses it as everyday. A worksheet is completed on density.
Curated OER
Solids and Liquids
Students investigate what happens to solids and liquids when they change from one form to another. For this states of matter lesson, students work in groups on a virtual experiment that requires them to collect data regarding the melting...

The Density of Liquids and Solids
There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...
Curated OER
The Same, But Different
Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...

Solids and Liquids
In this solids and liquids worksheet, students analyze the table of melting points of common materials in order to answer the questions given.
Curated OER
Properties of Liquids
Students describe properties of liquids and use descriptive language as a springboard to develop precise vocabulary for properties of liquids. They also use vocabulary as practiced with liquid-vocabulary card games. Finally, students...
