Lesson/Unit Plan

Overview:

In this lesson, students will be able to plan and carry out an investigation to compare the property of sinking and floating between different substances. Students will develop an understanding that whether a substance sinks or floats is a property of the substance. Students will look at several objects made from wax, wood, metal, and rubber and predict and test whether they sink or float.

Content Standard(s):

Science
SC2015 (2015)
Grade: 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).

NAEP Framework

NAEP Statement::
E4.6: Some Earth materials have properties either in their present form or after design and modification that make them useful in solving human problems and enhancing the quality of life, as in the case of materials used for building or fuels used for heating and transportation.

NAEP Statement::
P4.1: Objects and substances have properties. Weight (mass) and volume are properties that can be measured using appropriate tools.*

NAEP Statement::
P4.3: Matter exists in several different states; the most common states are solid, liquid, and gas. Each state of matter has unique properties. For instance, gases are easily compressed while solids and liquids are not. The shape of a solid is independent of its container; liquids and gases take the shape of their containers.

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.
