Sylvia GonzalesThird Grade

Objectives and Standards• The learner will learn what water is and the three states of water.• The learner will identify the path of the water cycle.• The learner will understand the roles water plays in the United States.

• 1.0 Listening and Speaking StrategiesStudents listen critically and respond appropriately to oral communication. They speak in a manner that guides the listener to understand important ideas by using proper phrasing, pitch, and modulation.

• Written and Oral English Language ConventionsStudents write and speak with a command of standard English conventions appropriate to this grade level.

• Sentence Structure1.1 Understand and be able to use complete and correct declarative, interrogative, imperative, and exclamatory sentences in writing and speaking.

• Physical Sciences • 1. Energy and matter have multiple forms and can be changed from one form to another. As a basis

for understanding this concept: e. Students know matter has three forms: solid, liquid, and gas. f. Students know evaporation and melting are changes that occur when the objects are heated.

• Investigation and Experimentationc. Use numerical data in describing and comparing objects, events, and measurements.

Fresh Water on Earth

• 97% - Salt Water• 3% - Fresh Water

- 2% = Ice - 1% = Usable Water

Fresh water is very valuable!

Water States…

• Water is constantly changing.• Water can exist as a solid, liquid,

or gas.

The Water Cycle

• “The path water follows as it evaporates into the air, condenses into clouds, and returns to the Earth as rain, snow, or hail.”

Water Cycle Path

• Water on Earth• Evaporation• Condensation• Precipitation• Repeat the Cycle

What have you learned?

• What percent of fresh water is usable water?

• What does the O stand for in H2O?

• Name one way water is used.• Name the three states of water.• Name and describe one step of the

water cycle.

Vocabulary

• Hydrogen- a colorless, flammable gas that is the lightest and most abundant of all gases

• Oxygen- gas in air we breathe

• Solid- of definite shape and volume; not liquid or gaseous

• Liquid- the state of matter in which a substance exhibits a characteristic readiness to flow, little or no tendency to disperse, and relatively high incompressibility

• Gas- a substance in the gaseous state

• Evaporation- to convert or change into a vapor

• Condensation- the process by which a gas or vapor changes to a liquid

• Precipitation- any form of water, such as rain, snow, sleet, or hail, that falls to the earth's surface
