Earth & Space ScienceAssessment Target: (K-4) Given certain earth materials (soils,
rocks or minerals) use physical properties to sort, classify, and describe them.

GSE’s – Earth & Space ScienceESS1 (K-2)–1Students demonstrate an understanding of earth
materials by … 1a describing, comparing, and sorting rocks and
soils by similar or different physical properties (e.g., size, shape, color, texture, smell, weight).
1b recording observations/data about physical properties.
1c using attributes of properties to state why objects are grouped together (e.g., rocks that are shiny or not
shiny).

Scientists study rocks for different reasons…
Let’s see what kinds of things we can find out from taking a close look at rocks and other earth materials in this unit.

Exploring Three Rocks…
Let’s take a look and see what we can
find out…
Examine the three rocks…•Color?•Size?•Shape?•Texture?
How are rocks different?
What do you
notice?

Our Unit…
•Students will investigate rocks and other earth materials (sand, silt, clay, soil).•Students will conduct experiments.•Students will sort and classify earth materials by looking at their physical properties and attributes.•Students will keep scientist journals to record predictions, observations, and claims and evidence.
![Page 24: Pebbles, Sand and Silt](https://reader033.vdocument.in/reader033/viewer/2022061617/568166de550346895ddb0ed7/html5/thumbnails/24.jpg)
PowerPoint
•Students will create a PowerPoint presentation slide with a partner that demonstrates some of the new learning acquired as result of this unit. •Students will use Wordle.net to share and record (in a fun way) some words learned in rock classification and sorting.
