Quarter 2 (unit 1)--Matter: Structure, Properties, and Change
Our first Science Unit for SECOND QUARTER will focus on Matter--Structure, Properties, and Change.
UNIT STANDARDS:
- 3.P.2 Understand the structure and properties of matter before and after they undergo a change.
- 3.P.2.1 Recognize that air is a substance that surrounds us, takes up space and has mass.
- 3.P.2.2 Compare solids, liquids, and gases based on their basic properties.
- 3.P.2.3 Summarize changes that occur to the observable properties of materials when different degrees of heat are applied to them, such as melting ice or ice cream, boiling water or an egg, or freezing water.
- 3.P.3 Recognize how energy can be transferred from one object to another.
- 3.P.3.2 Recognize that energy can be transferred from a warmer object to a cooler one by contact or at a distance and the cooler object gets warmer.
Our Essential Questions for the unit:
- What information about the properties of matter can be gathered by observation before and after a change? (3.P.2)
- How do the properties of solids, liquids, and gases compare? (3.P.2.2)
- Considering air is a mixture of gases, how does it compare to solids and liquids? (3.P.2.1)
- How might heat energy affect matter? (3.P.2.3)
- What are two examples of how energy can be transferred from one object to another? (3.P.3)
By the end of the unit, Students will know...
3.P.2.1:
- Students know that air surrounds us.
- Students know that air takes up space.
- Students know that air has mass.
- Students know that all matter exhibits properties. Matter can be differentiated based on properties.
- Students know that solids, liquids, and gases are all made up of particles. The behaviors of these particles differ in the three states (solid, liquid, gas).
- Students know that solids, liquids, and gases display unique properties characteristic of that particular state (phase) of matter.
- Students know that the characteristics of particular states (phases) influence the functional applications of a given material.
- Students know that when heat is applied to an object, the particles in that object begin to vibrate more rapidly and begin to move further apart.
- As particles move further apart, the object may change from one state to another (solid to liquid, liquid to gas).
- Students know that heating or cooling matter will alter the properties of that matter.
- Students know that objects can transfer energy by touching or by giving off or receiving energy waves.
- Students know that heat can move (transfer) from one object to another in more than one way. Heat energy can be transferred from a warmer object to a cooler object by contact (touching) or at a distance.
- Students know that when the transfer of heat energy occurs, the cooler object will get warmer.
- The effects of the transfer of heat energy can be observed using everyday materials such as water, air, cooking, and heating utensils.
