Lesson 7

Lesson Objectives...

• Develop and revise a model to predict and describe the unseen interactions between particles in a system to show that matter is conserved in a process where the type of particles that make up the starting substances (system inputs) somehow change through their interactions to make different type(s) of particle(s) in the ending substances (system outputs).

What we figured out this lesson...

• The same substance is made of the same type of particles throughout.

• Different substances are made of different types of particles throughout.

• The particles that make up the substances in the gas bubbles from a bath bomb must be different type of particle that any of those in the substances that were combined together to make it (water, baking soda, and citric acid).
