Physical Science

Matter: Properties and Change

These are the subjects that you will need to know this year and for your EOG.  Each section contains the following

5.P.2.1  Students know that the sun provides the energy that is a driving force for most biotic and abiotic cycles on the surface of the earth. Students know that the sun’s energy fuels the water cycle and impacts different aspects of the water cycle (evaporation, transpiration, condensation, precipitation).

EOG QUIZ

NC Standards - Matter: Properties and Change

NC Standards - 5.P.2.2

5.P.2.2  Students know that the weight of an object is equal to the weight of the sum of its parts.  This is true in all closed systems.

NC Standards - Matter: Properties and Change

NC Standards - 5.P.2.3

5.P.2.3  Students know that by making qualitative and quantitative data records, we are able to create before/after representations of materials (and their properties), so that we can compare before/after versions of materials.

Vocabulary

NC Standards  - Energy Conservation and Change

NC Standards - 5.P.3.1

5.P.3 Explain how the properties of some materials change as a result of heating and cooling.

5.P.3.1 Explain the effects of the transfer of heat (either by direct contact or at a distance) that occurs between objects at different temperatures. (conduction, convection or radiation).

5.P.3.1 Students know that when warmer things are put with cooler things, the warmer things lose heat and the cool things gain it until they are all at the same temperature. Students know that a warmer object can warm a cooler object by contact or at a distance. Conduction is the transfer of thermal energy between things that are touching. Conduction can happen within one object. (For example, thermal energy can be conducted through the handle of a metal pot.) Convection is the movement of thermal energy by the movement of liquids or gases. Convection in the oceans and atmosphere helps to move thermal energy around Earth, and is an important factor influencing weather and climate. Radiation is the transfer of energy by electromagnetic waves. Electromagnetic waves can carry energy through places with or without any matter. The Sun is the main source of electromagnetic energy on Earth. Part of this energy, light, is used by producers to make food. Radiation can also happen in other circumstances (i.e. sitting in front of a fireplace).

5.P.3 Explain how the properties of some materials change as a result of heating and cooling.

5.P.3.2 Explain how heating and cooling affect some materials and how this relates to their purpose and practical applications.

5.P.3.2 Students know that heating and cooling can cause changes in the properties of materials, but not all materials respond the same way to being heated and cooled. Students know that heating and cooling cause changes in the properties of materials, such as water turning into steam by boiling and water turning into ice by freezing. Students know and notice that many kinds of changes occur faster at higher temperatures. Students know that some materials conduct heat much better than others, and poor conductors can reduce heat loss.
