11. MOTIVATION Tell something about this picture. What do you think the man is doing?

12. LEARNING OBJECTIVE/S Objectives: At the end of the session, learners are expected to identify mixtures that can be separated through winnowing and identify the process of separating mixtures which uses winnowing technique.

13. ACTIVITY # 1 (Explore) Look closely at the picture of a man separating a mixture applying the process called winnowing. Answer the questions that follow. Activity 1 – Windy Encounter

14. ACTIVITY # 1 (Explore) Questions: 1. . What do you call the object used by the farmer to separate the mixture of rice grains and chaff? 2. What factor from the environment helps the farmer to do his work easily? 3. What occupation in your community uses this separation technique? 4. How will you describe the weight of the components that were separated? 5. Can we use this technique inside the house? Why?

15. ACTIVITY # 2 (Explore) The teacher will divide the class into five groups. Each group will do the following activity and will present their output in a creative way. Each presentation will be scored based on the rubrics provided. Activity 2 – To winnow or to sieve?

16. ACTIVITY # 2 (Explore) Activity 2 – To winnow or to sieve? CRITERIA At Standard (3) Approaching Standard (2) Below Standard (1) TOTAL ACCURACY The content of the lesson is clearly shown The team exhibits very clear ideas on the task related to their chosen field. There are vague ideas on the context of the task and their field of interest. There are unclear ideas on the context of the task given.   CREATIVITY Resourcefulness of the group with sense of uniqueness It exhibits high value of creativity and uniqueness without compromising all the contents of their output. It shows enough creativity and uniqueness compromising some of the contents of their output. It has low value of creativity of the group compromising the essential contents.   TEAMWORK Cooperation and involvement of members are revealing All members are cooperative and took each part that contributed to their success. Most of the members show involvement. Very few members take part in the activity.   PRESENTATION Clear explanation through presentation skills They clearly and fully explained new understanding gained in the activity. They explained some things learned in the activity but not entirely clear. They were not able to explain important new understanding gained in the activity.  

17. ACTIVITY # 2 (Explore) Activity Objective: To identify mixtures that can be separated by winnowing. Materials: Container/ plastic cups Plate/ flat container Sieve/strainer with varied hole sizes Dry sand Flour Rice grains Rise husks Sand Saw dust Small pebbles

18. ACTIVITY # 2 (Explore) Procedures: 1. Gather materials. 2. Sort separately the materials in different containers/plastic cup. 3. Discuss among your group your reason for sorting the objects. 4. Listen as the teacher discusses the difference of winnowing and sieving and how these methods are done.

19. ACTIVITY # 2 (Explore) 5. Choose five combinations of the materials and mix them in a separate container. 6. Try to predict first which method is more appropriate in separating the mixtures. Record it as your 1st method in the given table. 7. Perform the method of separation that you predicted and observe. Take note of the observations. 8. Try another method and observe how the materials are separated. This will be your 2nd method. 9. Decide which method is more appropriate in separating the materials by completing the given table

20. ACTIVITY # 2 (Explore) Materials 1 st Method Observation 2 nd Method Observation 1 2                                                        

21. ACTIVITY # 2 (Explore) Guide Questions: 1. Which mixtures did you predict can be separated by winnowing? Why? 2. Which mixtures did you predict can be separated by sieving? Why? 3. What properties of materials to be separated are appropriate for winnowing? Why? 4. What properties of materials to be separated are appropriate for sieving? Why?

22. Let each group present their outputs in a creative way. Learners will be scored according to the rubrics provided. Group 1- Rap/Singing Group 2- Newscasting Group 3- Talk Show Group 4- Drama PRESENTATION AND PROCESSING OF LEARNERS’ OUTPUT (EXPLAIN)

23. On the first activity, are you familiar with the scene in the picture? Some of you probably would say yes, but for most of the kids in your generation, you seldom see this activity now. The picture shows a farmer separating the mixture of grain and chaff (husk of palay or other seed) by using a device and with the help of the wind. Winnowing is a technique to separate lighter and heavier components of mixture by wind or by blowing air INPUT OF TEACHER

24. The rice grains are placed in a bilao (winnowing fan or winnower). Then the mixture inside this woven tray is tossed into the air so that the wind blows away the lighter chaff and letting the heavy grains fall back into the winnowing fan. Seems easy but winnowing is a difficult task. Now you know why it is not done inside the house! INPUT OF TEACHER

25. Activity 3: Preserving our Winnowing! Nowadays, technology is anywhere and everywhere. With today, advancement, some of our culture like winnowing or using a bilao to separate rice grains from chaff as a technique is slowly vanishing, what is the best way to preserve this technique as a separating mixture? APPLICATION (ELABORATE)

26. What technique in separating mixtures you have learned today? Winnowing is a technique to separate lighter and heavier components of mixture by wind or by blowing air. The rice grains are placed in a bilao (winnowing fan or winnower). GENERALIZATION (ELABORATE)

27. Complete the following ideas.   I learned that……… REFLECTION (ELABORATE)

28. Direction: Direction: Choose the letter of the best answer and write it in your science notebook. 1. What component of mixtures are applicable for winnowing?
