Georgia SKE2

SKE2 is a Georgia science standard. These are the elements under it.

• SKE2.a

  Ask questions to identify and describe earth materials—soil, rocks, water, and air.

• SKE2.b

  Construct an argument supported by evidence for how rocks can be grouped by physical attributes (size, weight, texture, color).

• SKE2.c

  Use tools to observe and record physical attributes of soil such as texture and color.

01

What Students Need to Do

Students observe rocks and soil, then use sealed bags or balloons to investigate water and air. They compare properties such as color, texture, size, shape, and movement, then share observations with words or pictures.

02

What Mastery Looks Like

A student can name observable properties of each material and support each description with evidence. The student can sort samples by one property and explain the sorting rule.

03

Common Misconceptions

Students may think air is nothing because they cannot see it. They may assume all rocks and soils look and feel alike. They may name an object's use instead of describing its properties.

04

How to Assess It

Show a rock, soil sample, sealed water bag, and inflated balloon. Ask each student to choose two, describe one property of each, and explain how they differ.

1. 01

   Set out rocks, soil, sealed water bags, balloons, hand lenses, and property cards for students to observe, match, and sort.

2. 02

   Ask, “How could you describe each material to someone who cannot see it?” Record student words and test whether each description fits.

3. 03

   Play Property Match by having students pair picture cards of earth materials with words such as rough, smooth, wet, clear, or moving.

4. 04

   Take a schoolyard walk to find rocks, soil, water, and evidence of moving air, then sketch one observed property of each.

• S3E1

  Obtain, evaluate, and communicate information about the physical attributes of rocks and soils.

• S6E5

  Obtain, evaluate, and communicate information to show how Earth's surface is formed.

• SKP1

  Obtain, evaluate, and communicate information to describe objects in terms of the materials they are made of and their physical attributes.
