Waterproof & Absorbent Materials Instructional Objective (Measurable) After the lesson student should be able to: - Distinguish between waterproof and water absorbent materials. Qatar curriculum Standard: 9.1 Classify materials in various ways on the basis of their physical properties (P.92). Materials: 1. Hand lens 2. 26 piece of worksheets (P.43) 3. PowerPoint Resources: 1. Collins Science Directions Pupil Book 1 by Chris Sunley, Jone Bourne, Alison Norman. 2. Collins Science Directions Teaching File 1 by Chris Sunley, Jone Bourne, and Alison Norman. TEACHING PROCEDURE: Activating prior Knowledge/ Focus: 1. Play material guessing game: Students must guess what the object is that has been placed in their hands (hands behind your back and no looking!) by the other students; they must also identify what material the object is made of. One student will come to the front of the class, turn so their back is facing the class with their hands behind them. Another student is asked to select one item (sponge, plastic spoon, pencil and rubber) and to place it in the other student’s hands. The student with back turned must then guess and answer, what is the object? What is it made of and what they know about its property?. 2. Ask them “what was about our last lesson?” Let them answer” properties of materials” Then tell them today we will learn about waterproof and absorbent which is property of some materials. and then ask them if they have any idea about the meaning of these words. Teacher Strategies Students Activities 1. Ask what is the important property of the materials which umbrellas are made from? 2. What should umbrella do with rain water? 3. Explain them that some materials do not let water pass through them; they do not become wet for example, plastic. We call these materials, waterproof materials. Some of it used to make umbrellas. Then ask them to give you another example of waterproof materials. 4. Ask them wood is water proof but what will happen to the wood if it is under the rain for long time? Then tell them do you know why? May the students do not know the answer? Explain that “because wood is both waterproof and absorbent! It is waterproof but gradually it absorbs water and become wet, then it will start to spoil and break down”. “Put the rain water away from people”. “Wood, metal and glass”. “ It will spoil and will breakdown” ‘Because it can not tolerate water for long time” 5. Some materials, if you use a hand lens you can see small holes. Water will be able to pass through these small holes Students will say “it is absorbent because what do you think we call it? the water goes in so it becomes wet”. 6. Tell them “Excellent we call these materials water absorbent materials, such as sponge”. Ask them to give you Students will tell examples white paper, tissue paper, towel paper, wool, clothes. examples. 7. Show them different materials on the PowerPoint or real materials if it is possible. 8. Give each student a hand lens and let them test there clothes, paper, bags plastic paper to see the wholes and to say which one is water proof and which is The students will use the hand lens absorbent. testing the materials. 9. Let them figure out the materials in the class and to say which one is waterproof Students will figure out the materials and and which one absorbent. will say which one is waterproof and which absorbs water. 10. Give them worksheets, explain for them the questions and what they have to do then, let them work on it to answer the questions. Check their work while they Students will answer the worksheets. are working. Modifications/ Differentiation: - Encourage the students who have difficulty in understanding, and let them participate with the group during the activities and check them while they are working on the work sheets. - Let them share in material guessing game. Lesson Extension: Ask them to write sentences about what they saw under the hand lens while they are checking different materials. Closure: 1. Remind them the vocabularies (absorbent and waterproof) and let them say the meaning of each. 2. Let them give you example of waterproof and absorbent materials. 3. Tell them tomorrow we are going to measure different paper towels absorbency. Assessment: Use a rubric to: 1. Assess the students whether they could recognize the materials with property of waterproof, absorbent or both, during their participation in the lesson answering questions and working actively on the lesson activities. 2. Assess the students by grading their worksheets. Reflection: My lesson ( waterproof & absorbency), the students enjoyed it because I put many activities for example different gloves( of plastic, rubber, and wool) and I allowed each of the students to check the gloves, one by one and to say whether it is waterproof or absorbent. I gave each of them hand lens to check their clothes and different materials to see that there is holes in absorbent materials, which allow the water pass through, and to see that waterproof materials like plastic do not have these holes so the water don’t pass through it and it not become wet. I enjoyed the lesson while I’m teaching. The plan went well and on time. Name: …………………………………. Date: ………………………. 1.

Name:…………………………………… CATEGORY Date:……………………………… 4 3 2 1 Participated in the lesson, answering the questions & she shared actively in the lesson’s activities. She sorted the materials into waterproof & absorbent correctly. Participated in the lesson, answering some questions & she shared in the lesson’s activities. Participated a little in the lesson. Tried to answer one question & she shared in one activity. She sorted the six materials into waterproof & absorbent with two mistakes only. Completing sentences in the w/sheet She completed the sentences correctly. Identifying the words (waterproof & absorbent) She identified the 2 words correctly and fluently. She completed the sentences with 1 mistake of the four words in the gaps. She identified the 2 words correctly but not fluent. Not active, she participated in one activity and she didn’t answer any question during the lesson. She sorted the six materials into waterproof & absorbent with 3 or 4 mistake. She completed the sentences with 1 correct word of the four in the gaps. She couldn’t identify the 2 words and she needed more help from the teacher. Participation in the lesson Sorting materials in the w/sheet Evaluation score of the lesson: She sorted the six materials into waterproof & absorbent with one mistake only. She completed the sentences with 2 mistakes of the four words in the gaps. She identified the 2 words correctly but not fluent and with teacher’s help. Score Total score: ……………………… 1. If the student scored 14 to 16 she is processing proficiency. She should be challenged with advanced work. 2. If the student scored 10 to 13 she is processing well. She can be improved by participating more in class activities. 3. If the student scored 7 to 9 she is still developing. She need extra guide and help from the teacher to master the key concept.
