Science 8 Lesson 17 Content Standard: The learners demonstrate an understanding of the particle nature of matter as basis for explaining properties, physical changes, and structure of substances and mixtures. Performance Standard: The learner should be able to … present how water behaves in its different states within the water cycle. Science 8 Lesson 17 Change of State in the Water Cycle Component 1: Short Review Time: 7 minutes Q1. Where does the water come from when it rains? The water comes from the clouds. Component 1: Short Review Time: 7 minutes Q2. What are the two important physical change of states that drive the water cycle? The two important changes of state are evaporation and condensation. Component 1: Short Review Time: 7 minutes Q3. Explain the important role of the sun in the water cycle.? The heat from the sun evaporates the liquid water in the oceans to form water vapor in the atmosphere Component 1: Short Review Component 2: Lesson purpose/Intention Time: 3 minutes This lesson is about reading diagrams and how important Time: 7 minutes completing diagrams is for learning and when answering questions in science. The lesson is about physical changes. We want to be sure we know and understand the water cycle in terms of physical changes. - Explain physical changes in terms of the arrangement and motion of particles. S8MT-IIIcd Component 1: Short Review Time: 7 minutes Component 3: Lesson Language Practice Component 1: Short Review Time: 5 minutes The diagram below shows how scientists explain changes of state in the Time: 7 minutes water cycle. Q1. In which box is the water a gas? Component 3: Lesson Language Practice Component 1: how Short Review The diagram below shows scientists explain changes of state in the Time: 5 minutes water cycle. Time: 7 minutes Q1. In which box is the water a gas? The water is a gas in the middle box (Box B) Component 4: Lesson Activity Component 1: Short Review Time: 25 minutes Component 4A Time: 7 minutes The Water Cycle The water cycle is the path that all water follows as it moves around the Earth. It is a continuous process. 1. Water evaporates into the atmosphere because of heat from the sun. 2. Water evaporates into the atmosphere form the transpiration of plants. 3. When it cools, water condenses in the clouds. 4. Water falls as rain on the oceans and the lands. 5. The rain might be frozen as ice or snow 6. The snow and ice can melt from the sun’s heat. Component 1: Short Review Choose the answer inside the box. Time: 7 minutes Condensation Transpiration Evaporation Precipitation 1. A change from a liquid to a vapor. Component 1: Short Review Condensation Evaporation Time: 7 minutes Transpiration Precipitation 1. A change from a liquid to a vapor. Answer: Evaporation Component 1: Short Review Condensation Evaporation Time: 7 minutes Transpiration Precipitation 2. The act or process or an instance of transpiring Component 1: Short Review Condensation Evaporation Time: 7 minutes Transpiration Precipitation 2. The act or process or an instance of transpiring Answer: Transpiration Component 1: Short Review Condensation Evaporation Time: 7 minutes Transpiration Precipitation 3. The conversion of substance (such as water) from the vapor state to a denser liquid or solid state usually initiated by a reduction in temperature of the vapor. Component 1: Short Review Condensation Evaporation Time: 7 minutes Transpiration Precipitation 3. The conversion of substance (such as water) from the vapor state to a denser liquid or solid state usually initiated by a reduction in temperature of the vapor. Answer: Condensation Component 1: Short Review Condensation Evaporation Time: 7 minutes Transpiration Precipitation 4. The act of, process, or instance of precipitating.

Which Time: 7 minutes part of the cycle needs heat from the sun? The evaporation of water from the oceans won’t happen without heat from the sun. omponent 4: Lesson Activity Component 1: Short Review me: 25 minutes Component 4C Time: 7 minutes Q2. . Complete the following sentence “Water exists n the liquid form in the …………... and in the …………….….”. “Water exists in the liquid form in the oceans and in he clouds.”. omponent 4: Lesson Activity Component 1: Short Review me: 25 minutes Component 4C Time: 7 minutes Q3. How would the water cycle be affected if there is a very long period of hot sun? In long periods of hot sun more water than usual will evaporate, and this could cause a drought.
