2 Content Area: ScienceGrade Level: Grade 2Summary: The purpose of this PowerPoint is to help students identify how temperature changes affect the state of matter describing the three phases of the water cycle.Objective Target: Given the websites on the topic of the water cycle, the student will be able to recognize the three phases of the water cycle with 100% accuracy.Standard: GLE Investigate how temperature changes affect the state of matter.
3 Things you need to know about the water cycle. Watch this video about the water cycle to help you answer the questions in this lesson.Water Cycle VideoClick on the following link and fill out the KWL Chart:actives/kwl_creator/The earth is made up of lots of water, and the water keeps going around and around and around and around. This is called the Water Cycle!The water cycle is made up of three main phases: evaporation, condensation, precipitation.Things you need to know about the water cycle.
4 More things to Know about the water cycle Water in the water cycle can exist as a solid, liquid, or gas. The water cycle is very important to life on Earth.The sun is the driving force of the water cycle.Click on these links to learn more!Water Cycle GameMore things to Know about the water cycle
5 Evaporation is a process of a liquid changing into a gas Evaporation is a process of a liquid changing into a gas. An example of evaporation is water turning into steam.Condensation is the opposite of evaporation. Condensation occurs when a gas is changed into a liquid.Precipitation is water released from clouds in the form of rain, sleet, or snow.Water Cycle Facts
6 condensationevaporationprecipitationWhen the sun heats up water and turns it into vapor or steam what is this called?
7 You Got it!Evaporation is when the sun heats up water in rivers, lakes, or the ocean and turns it into vapor or steam.
8 Rain, sleet, and snow are examples of which phase of the water cycle? evaporationcondensationprecipitationRain, sleet, and snow are examples of which phase of the water cycle?
9 Great Job! Precipitation happens when the clouds get heavy with water and the water falls back to the earth in the form of rain, sleet or snow.
10 condensationcloudsevaporationWhen water vapor in the air gets cold and changes back into a liquid forming clouds. What is this called?
11 Way to Go! Yes, as water vapor in the clouds cools down it becomes water again, this process is called condensation.
12 In this lesson you were able to identify the three phases of the water cycle; evaporation, condensation, and precipitation.In this lesson you learned that when water is heated by the sun, and the water turns into steam this is called evaporation.In this lesson you learned that rain, sleet, and snow are all examples of precipitation.In this lesson you learned that when water vapor in the air gets cold it changes back to a liquid and forms into clouds, this is called condensation.Summary
