Overview

In these Hero Elementary activities, children explore solid and liquid materials. They observe, compare, and describe solid and liquid materials. They sort materials as solid or liquid. They find out how hot and cold can change the state of materials.

    SC15.2.1

    Conduct an investigation to describe and classify various substances according to physical properties (e.g., milk being a liquid, not clear in color, assuming shape of its container, mixing with water; mineral oil being a liquid, clear in color, taking shape of its container, floating in water; a brick being a solid, not clear in color, rough in texture, not taking the shape of its container, sinking in water).

    • Substances
    • Conduct
    • Describe

    Knowledge

    Students know:
    • Different kinds of matter exists.
    • Properties of both solids (opaque, transparent, translucent, rough, smooth, float, sink, has its own shape) and liquids (color, assumes shape of container, opaque, transparent, translucent).
    • Many types of matter can be either solid or liquid, depending on temperature.

    Skills

    Students are able to:
    • Plan and conduct an investigation to produce data that is used to describe and classify substances according to physical properties.

    Understanding

    Students understand that:
    • Observable patterns in the properties of materials provide evidence to classify the different kinds of materials.

    SC15.2.4

    Provide evidence that some changes in matter caused by heating or cooling can be reversed (e.g., heating or freezing of water) and some changes are irreversible (e.g., baking a cake, boiling an egg).

    Unpacked Content

    UP:SC15.2.4

    Vocabulary

    • Properties
    • Evidence
    • Change
    • Matter
    • Heating
    • Cooling
    • Reversible
    • Irreversible

    Knowledge

    Students know:
    • Characteristics of materials before heating or cooling.
    • Characteristics of materials after heating and cooling.
    • Characteristics of materials when heating or cooling is reversed.

    Skills

    Students are able to:
    • Analyze evidence to support a claim that heating and cooling causes change in matter.

    Understanding

    Students understand that:
    • Heating or cooling a substance may cause changes that can be observed. Sometimes these changes are reversible and sometimes they are not.
