Unit Two: Physical Science

In this unit...

Students will understand that...

• U1 Matter can be described, organized, and classified for understanding the world.

• U2 Matter has physical properties that can be measured and observed using tools.

• U3 Characteristics of objects make them useful.

• U4 Matter can be changed/manipulated but cannot be created or destroyed.

• U5 Energy exists in many forms all around us and can be observed in patterns, systems, and cycles.

Students will keep considering the following questions:

• How do science and engineering impact your life?

• Why should you always keep wondering?

Students will work on the following skills/concepts:

• K1 matter can change from one state to another when energy is added to or taken away from it.

• K2 properties of a solid, liquid, and gas.

• K3 mixtures can be made by combining solids with liquids, combining liquids with gasses, or combining solids with gasses.

• K4 creating a mixture may change the physical characteristics of the combined substances, but their properties do not change.

Students will be skilled at:

• S1 using appropriate tools and techniques to gather, analyze, and interpret data about physical properties of matter, how matter changes, and forces

• S2 using evidence to develop descriptions, explanations, predictions, and models.

• S3 making predictions based on observable patterns.

• S4 designing and conducting investigations.

• S5 communicating scientific explanations and valid conclusions.

• S6 defining a simple problem and finding solutions.

• S7 reading texts and/or using media to obtain information.
