Unit 3: Properties of Matter

Performance Expectations:

• 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-PS1-3: Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.

• 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-ETS1-2: Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

• MS-ETS1-3: Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristic so each that can be combined into a new solution to better meet the criteria for success.

• MS-ETS1-4: Develop a model to generate data for interactive testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

Essential Questions:

• What are chemical and physical properties of matter?

• What determines if a substance is going through a chemical or physical change?

• What happens to substances during chemical reactions?

• How do characteristic properties identify substances?

• What is the Law of Conservation of Matter?

• How are synthetic materials formed?
