7.1 Lesson 4 Students will investigate the question: Which combinations of substances in a bath bomb produce a gas?  

Standards: 

• MS-PS1-1

• Develop models to describe the atomic composition of simple molecules and extended structures.

• MS-PS1-2

• Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.

• MS-PS1-5

• Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.

• MS-LS1-8

• Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories.

Warm-Up: Today's Reading

Key Model Ideas

• Gases, liquids and solids are all matter

• Matter has mass and takes up space

• All matter Is made of particles

• In a closed system, no matter can get in or out, so the mass stays the same.

• In an Open System, matter can get in and out so the mass can change if that happens
