Conservation of Mass Science Games

In this series of games, your students will learn that no matter what reaction or change in properties occurs, the total weight of the substances does not change. Conservation of Mass learning objective — based on NGSS and state standards — delivers improved student engagement and academic performance in your classroom, as demonstrated by research.

Concepts Covered

During a physical change, the physical properties of a substance change but the chemical properties are the same. Changes in state are physical changes. During a chemical change, the chemical properties of a substance change, and a new substance is formed. In a physical or chemical change, the total weight of the substances remains the same before and after the change occurs.

The law of conservation of mass states that mass is never created or destroyed. The three common states of matter on Earth are solid, liquid, and gas.

A mixture is a combination of two or more substances. Solutions are formed when one substance dissolves in another. A solution is a mixture of two or more substances that are evenly distributed.

Matter can change from one state to another when a substance is heated or cooled. Freezing occurs when a substance changes from a liquid to a solid. Melting occurs when a substance changes from a solid to a liquid. Evaporation occurs when a substance changes from a liquid to a gas. Condensation occurs when a substance changes from a gas to a liquid.
