[|Gr. 1 TEKS Introduction]
 * __TEKS Science Concepts__**


 * 1.7 Earth and space. The student knows that the natural world includes rocks, soil, and water that can be observed in cycles, patterns, and systems. The student is expected to: **

1.7A Observe, compare, describe, and sort components of soil by size, texture, and color.


 * 1.7B Identify and describe a variety of natural sources of water, including streams, lakes, and oceans. **

1.7C Gather evidence of how rocks, soil, and water help to make useful products.


 * Day One: **

Fundamental Questions

 * What are some natural sources of water?
 * What observable characteristics can we use to identify and describe natural sources of water?

Background for Teacher
Bodies of water on Earth have different properties that differentiate them from others. Streams are smaller bodies of moving water, while rivers are larger and in general have been more established. A lake is a standing body of water, but can be connected to other rivers or streams and ultimately connected to the ocean. In general, streams, lakes, and rivers are freshwater, although there are a few salt-water lakes around the world. The oceans are salty, and make up two thirds of the planet. Have students reflect on these properties and any other observable properties students can identify given the pictures given.

Procedure

 * 1) Begin by asking students about where they have seen water, and what it looked like.
 * 2) Display the slides of the bodies of water in the presentation, and have students name or describe each as a class.
 * 3) Students can then answer the questions in the ‘Think-Pair-Share’ portion of the activity.
 * 4) After reviewing responses lead into the Reflection questions.
 * 5) Introduce the Explore activity.

Slideshow for Bodies of Water from Stemscopes
