2-ESS2-2

SCUSD NGSS Curriculum Guide

**2-ESS2-2: Develop a model to represent the shapes and kinds of land and bodies of water in an area.** [//Assessment Boundary: Assessment does not include quantitative scaling in models.//]

Science Background for the Teacher:
The Earth is composed of land (contents) & water (oceans, lakes, ponds, rivers & streams). Wind and water shape the form of land.

Key Vocabulary:

 * land || continents || ponds || mountains || sand ||
 * water || lakes || streams || rocks ||  ||
 * oceans || rivers || valleys || soil ||  ||

Possible Assessments (formative and/or summative):
Make an individual 2D labeled diagram model. Students must label the different forms of water and land on a diagram.

Key Student Activity:
Soil investigation from 2nd grade Foss Kit Hands on class 3D model with clay t o teach the different forms of land and water. Sand models

Key Teacher Demo/Activity:
Foss Science Resource Book for Pebbles, Sand, and Silt Foss Investigation 3 and 4 from Pebbles, Sand, and Silt Kit

Common Student Misconceptions:
What is a model? Models can be 2D or 3D. Some examples include maps, globes, computer models, animation, graph, or relief map.

Things to Avoid/Correct:
Students need to understand that there is land under the water.
