1. Workshop 5: PROFILES JONABEL B. BUSTILLO Binalonan I/BNCSSC

2. Objectives of the Workshop • Demonstrate knowledge of interconnections of concepts across disciplines using one concept as basis.

3. • Create a logical Profile of a given scientific term(s) ensuring that the information provide an ample description.

4. • Acknowledge the importance of “Profiles” in the learning process.

5. What are profiles? Serve as text organizers and outlines. They are templates. It organizes or reorganize information

6. Why use profiles? •It helps the students follow the patterns of organization that give text meaning.

7. •To help students to concentrate on the scientific information they need to impart with minimum concern about the beginning, middle, and end of their writing.

8. •If the student learns to write text consistently organized, they learn to internalize the “sound” of good writing, so that eventually they can organize their writing independently and in their own voice.

9. Introducing Profiles

10. Profile of an Element Complete the information in this Profile. Then write a story or an article about the element you have selected. Be sure to follow the organization of the Profile. • Select any element from Group 1A, 2A, and & 7A which can also be found in Period 2 or 3 of the Periodic Table: ________

11. • Is the element coming from the s or p block? ._______ • What is the nature of the element? __________ • Write the electronic configuration of the element. _________

12. • Is it capable of combining covalently with other elements found in the same groups and periods mentioned in the 1st statement? ________. Why? ________ If yes, how many electrons can it share? ________

13. • Can this element give up its valence electrons when bonding with other elements as mentioned in statement 1? _______. Why? ______ If yes, how many electrons can it give up? ______

14. • What is the element? _______ •Are there any other information you can add to this profile? ______

15. Profile of an Element (Sample Response) • Select any element from Group 1A and & 7A which can also be found in Period 2 and 3 in the Periodic Table. Magnesium • Is the element coming from the s or p block? s block

16. • What is the nature of the element? It is a metal/metallic • Write the electronic configuration of the element. 1s2 2s2 2p6 3s2 • Is it capable of combining covalently with other elements found in the same groups and periods mentioned in the 1st statement? Yes

17. Why ? ________ If yes, how many electrons can it share? Continuation •Can this element give up its valence electrons when bonding with other elements as mentioned in statement 1? Yes

18. Why? When this element combine with elements in Group 7 to form an ionic compound it tends to give up or donate its valence electron to the non-metal to attain a stable electron configuration. If yes, how many electrons can it give up? 2 electrons

19. Continuation •What is the element? Magnesium •Write the symbol of the element Mg •Are there any other information you can add to this profile? Being a metal, Magnesium is malleable, ductile, and capable of conducting electricity.

20. Profile of an Element (Sample Story) Every element in our Periodic Table has a story. Here is a part of the story related to one of them - Magnesium.

21. Magnesium is located in Group 2A, Period 3 with an atomic number of 12. Thus it belongs to the s block of elements. It is metallic. This description can be checked through its electronic configuration: 1 s2 2s2 2p6 3s2 . Elements with 3 or less electrons in their outer energy level are classified as metals.

22. The arrangement of electrons showing Magnesium’s 2 valence electrons can tell too that the 12 electrons of the element occupy 3 energy levels, indicating its period number 3. Continuation

23. Magnesium is not capable of combining covalently with other elements found in Groups 1A, 2A and 7A and periods 2 and 3. However, it is willing to give up or donate its 2 valence electrons to any element in Group 7A to attain a stable configuration following the rule of 8 (Octet Rule). One example is Magnesium chloride, MgCl2.

24. Magnesium is represented by its symbol Mg. Being a metal, it has the following characteristics: malleable, ductile, and capable of conducting electricity.

25. Can we do it?

26. Workshop Instructions Each group may use the out put from the Defining Format session (Session 4) or choose a new term, from their taxonomy.

27. Your goal is to create a Profile of the term, similar to a resume. You decide on the information you will provide. The earlier example can be guide.

28. Using the Profile as basis, write the information in paragraph form. Exchange with other groups and use their Profile Responses a basis to write the Profile Story.

29. Present the group’s work for discussion. Time allotment for the activity: 25 minutes

30. Presentation of Outputs

31. Points for Discussion Were the Profiles logically constructed and have provided enough description of the term(s)?

32. Can we include Profiling in our teaching-learning process? What possible problem(s) may arise if you do the activity? How would you response to it?

33. What probable value would this strategy have to your teaching - learning process?

34. Rubrics for Write For Science Profiles Strategy Strategy/Points 4 3 2 1 Profiles Completes researches and science information for a Profile. Completed most of information Shows limited information in Profile. Very little information in the Profile.

35. Wrap-Up Writing in the discipline requires: important details; presenting the information logically ensuring that the information provides a complete description

36. Thank you for your kind attention….. God bless po ..
