Teacher Input:
T: Good morning class! I need everyone to come and sit on the floor for this morning’s lesson. Were going to listen to a song and I need everybody to think of what were going to be learning about today.
S: Quietly go and sit on the floor.
S: Water, Water Cycle, Evaporation.
T: Great job! Those are all excellent ideas. Today we will be exploring the Earth’s water cycle. How many of you have heard of the water cycle?
S: (Students raise hands if they know about water cycle).
T: Okay, since we are talking about the water cycle this morning, what comes to mind when you hear the word water?
S: Rain, lake, ocean, clouds, streams, drink water.
T: That’s correct. Those are some great ideas. Now let’s see what the water cycle actually is.
T: (Teacher reads definition from Powerpoint). The water cycle is how water keeps going around and around. It evaporates, forms clouds in the sky, and then returns to earth again as rain or snow.
T: What do you think is most important about that definition. (Call on students)
S: The water cycle keeps going around and around.
T: That’s right, good job! The water cycle does keep going around and around and is always happening on Earth.
T: (Call on several student’s) Can you tell me what the water cycle is? Turn to your neighbor then tell them what the water cycle is.
S: Students respond with definition given on powerpoint.
T: Now since we all know what the Water Cycle is we are going to read The Magic School Bus Wet All Over: A book about the Water Cycle by Patricia Relf.
T: I need everybody to listen for important words that might fit in with the water cycle.
(Teacher reads the story to the class.)
QUESTIONS ABOUT BOOK!!!!!!!!!!!!!
T: Take a look at these pictures on the overhead. What might you think you would have in common with dinosaurs and George Washington? Can you really believe you would have the something in common with these items shown?!
S: We drank the same water.
T: That’s right!! We could be drinking the same water as the dinosaurs were drinking. How do you think water from George Washington or dinosaurs’ time could have possibly made it into the water we are using now?
S: Water is an on-going cycle.
T: That’s right, there is the exact same amount of water on earth today as there was a million years ago and remember, water is an ongoing cycle. The water is what kind of cycle class?
S: An ongoing cycle!
T: Now since we all know what a water cycle is we are going to explore the different phases of the water cycle. After reading the book and listening to our song does anyone know what one of the phases could be?
S: Evaporation, Condensation, Precipitation.
T: Those are all correct! You guys are doing a great job listening. Let’s take a look at our first phase Evaporation.
T: (Reads from Powerpoint) Evaporation is when the heat from the sun or another source causes water to go up in the form of water vapor. By looking at the slide, can anyone tell me an example of evaporation?
S: Fog.
T: Very good! Fog is one form of evaporation and you can see it some mornings. Who can tell me what happens when all the snow outside melts, where does it go?
S: It melts.
T: That’s right it does melt, then on a bright sunny day the sun soaks up all that water and is part of evaporation. (Call on student) Can you tell me what evaporation does?
S: Its when the sun causes the water to go up to the sky.
T: Good, now can someone give me an example of evaporation?
S: When it is foggy outside.
T: That’s right! Okay now the next step in the water cycle is called condensation. Can everyone say that together?
S: Condensation.
T: Very good. Condensation is when water vapor turns to water droplets as it lifts and gets colder. All these droplets come together to form clouds! Then when the clouds get too big and has too many water drop lets the water returns to earth as precipitation.
T: When the weather gets colder or warmer is when the droplets of water lift to form clouds?
S: When the weather gets colder.
T: Very good. Now can anyone guess what might happen next in the water cycle?
S: The water comes back down, it rains.
T: Great job! You are correct. The next phase in the water cycle is called precipitation. Let’s all say it together now.
S: Precipitation.
T: Precipitation is how the water returns to earth. It can be rain, snow, sleet or hail.
T: Can everybody see now how we drank the same water as the dinosaurs? The water keeps being reused over and over again.
T: There is one more phase to complete the cycle and that is called accumulation. This is when the water falls back into the lakes, streams, and oceans and the cycle starts all over again.
T: Now lets all say the 4 phases of the water cycle together.
(Class says the four phases: evaporation, condensation, precipitation, accumulation.)
T: Very good. (Call on student) Can you tell the class what the four phases of the water cycle are?
S: Evaporation, Condensation, Precipitation, Accumulation
T: Great work. Now let’s take a look at our water cycle poster. I need some help to place the correct picture and word on the poster.
S: (students take turns coming and sticking the correct picture or word to complete the water cycle)
T: Very good. Can I have a volunteer to tell the class what is happening on the water cycle poster?
S: Student lists the different phases.
Guided Practice:
Independent Practice:
Student Evaluation:
The teacher will have the assistant pass out worksheet #1 “Let’s Complete the Cycle”. Once each student has received the worksheet, the teacher will read the directions. The teacher will then ask the students to read the directions along with him. The teacher will check for understand with two different students, and then ask if anyone has any questions. The teacher will tell the students that when they finish the worksheet is should be turned over. The teacher tells the students they will have about 10 minutes to complete the worksheet and to bring it to the front when it is completed. If the students forget any of the steps they can look at the poster for help. After 10 minutes all the worksheets should be brought to the front of the class.
Homework:
The teacher will have the assistant pass out worksheet #2 called “Let’s see what you learned”. Once everyone has a copy of the worksheet, the teacher will read the directions. The teacher will then ask the class to read the directions together. The teacher will then check for understanding with one or more students. Next, the teacher will answer any questions the students may have.
Closure:
T: We have learned a lot today about the water cycle. Let’s do a quick review to make sure we all remember the four phases of the water cycle.
T: I am going to ask a question to the student sitting next to me then he/she will answer then ask the same question to the person sitting next to him.
T: (Asks student question) what are the four phases of the water cycle?
S: Evaporation, condensation, precipitation, and accumulation
(Continue around the circle until everyone in the class has asked the question and answered the four phases)
T: Great job everybody! I hope we all learned something new about the water cycle today.
