TODAY'S LESSON:
Unit topic/ Theme: Environmental Science

Grade: 1st/2nd

Lesson topic: Water Cycle

Objective/SWBAT: Students will able to identify the four stage of the water cycle(precipitation, evaporation,condensation,and collection) and Student will also be able to describe each stage.

Instruction methods: Discussion, group work, computer work, in class lab demonstration and worksheets

Materials

• Computers with website already open

• Worksheet #1( Intro assessment)

• Worksheet #2 (Notes)

• Worksheet #3 (HW/ assessment)

• websitelessons.e-learningforkids.org/efk/Courses/EN/The_Water_Cycle/launch.html

• www.kidzone.ws/water/index.html

• Bunsen burner/electric heater & beaker

• Book or cardboard

Procedure

1. Handout Worksheet (Blank worksheet that has pictures of different stage of the water cycle) The Four words Precipitation, Condensation, Evaporation, and Collection will be written on the board as a word bank. Student will attempt to label the pictures with the corresponding words. The students are encouraged to guess and they won’t be penalized for wrong answers. This activity should not take longer than 5 mins. As a class discuss why students answered the way they did, have them explain why.(Take note of who see to know the concept and later put these students in groups with students who tend to struggle in class). After this collect the worksheet and use this to gauge what the student know and compare it to final assessment to growth.

2. Break students into groups of 2-3 ,assign them to computer (if possible pair students who struggle in class with student who know the concept) Hand out the second worksheet to each student.( this worksheet is double sided, The front is has images of the water cycle and the back has the four key words Precipitation, Condensation, Evaporation, and Collection with a few lines under each word for the explanation of why event happens) students should use the worksheet to take notes on while using the website and during the lab demonstrations. The website the student will be using is websitelessons.e-learningforkids.org/efk/Courses/EN/The_Water_Cycle/launch.html. Preload the website on all the computer before class starts. The website follows the narrator Explorer Dan as he ventures through the water cycle For each stage Explorer Dan will explain what the different stages are and tell why each one happens. After he goes over the topics, the website quizzes the student several times. The website has the students identify the topic via pictures and definitions.The website should take around 5 minutes. The student should be reminded, while using the website they should be taking note on the second worksheet.

3. Come back together as a class to review the water cycle and explain in depth about water cycle using www.kidzone.ws/water/index.html. Read aloud all the information about what happens during each stage of the water cycle provided on this page. Once the class has finished reading through all the information, scroll down to the worksheets provided at the bottom of the page. Have the students all sit in a spot where they can see you, as you will be performing the experiments provided as a demonstration (helpful for visual learners). Ask students to take notes on their observations. They will be used for a class discussion afterward.** Before doing any experiments with students go over safety with the class. Discuss the dangers and importance of proper safety.**

1. Worksheet #2: “Make Your Own Evaporation” - Using a bunsen burner, heat up some water in a small beaker. As the water warms up, have the students watch closely for signs of evaporation. Point out the steam as it begins to rise from the water in the beaker to the class.

2. Worksheet #3: “Condensation” - To show students condensation in action, place a piece of cardboard or a book in the freezer for about an hour. When the book (or cardboard) is ready, take the beaker of boiling water from the evaporation experiment and hold the book about one foot over the opening of the beaker. Have the class take note of the water droplets that begin to form on the book.

3. Worksheet #4: “Precipitation” - This experiment is a continuation of the condensation experiment. If you continue to hold the book above the beaker, eventually the droplets become too heavy for the book to hold, and they will begin to fall.

4. Worksheet #5: “Collection” - After the precipitation part of the experiment, have students pay attention to where the water droplets land. This is collection.

Class discussion: Ask students to share some of their observations. During this

discussion, encourage students to ask any questions to clear up any confusion they may have.

4. Hand out Homework/Take home assessment.(The worksheet asks the students to fill in the blank using the key words and on the back students will asked to describe each stage/key words of the water cycle.) Hand out this assignment out at the end of class. Students will be permitted to use the worksheet they filled out in class (worksheet 2). This will show the instructor if the students retained any information. The assessment combined with the pre-assessment this will be able determine how effective the lesson was.
