  • I would HIGHLY recommend the bulimia recovery program. Shaye and the girls on the site are beyond amazing. Without even meeting anyone, I have felt kindness, love, and incredible support. For that reason alone it is worth it. But the guides, information, meal planning tools, binge tracker, blog, forums, and vidoes are more reasons to join. I truly think that if you struggle with an eating disorder this program will help you overcome it and change your life for the better. ★★★ http://t.cn/A6Pq6KF6

E:CDD FilesBEC-PELC Finalized June 2010COVER PELC - Science.docx Printed: 8/12/2010 11:25 AM [Anafel Bergado] 1 (Philippine Elementary Learning Competencies) BASIC EDUCATION CURRICULUM SCIENCE AND HEALTH SCIENCE AND HEALTH BUREAU OF ELEMENTARY EDUCATION Department of Education Republic of the Philippines JUNE 2010
  2. 2. PREFACE Science educators throughout the world have been espousing the idea that the best way to learn science is by “doing science”. We all share in a vision of achieving excellence in Science and Technology at par with that of developed countries. Science and Technology are shaping the world. Social and economic development area, to a large content, is dependent on Science and Technology. The learners should be given enough time to perform the activity, record data, analyze and interpret results and discuss and evaluate within groups and with the whole class. The learning objectives herein aim to provide the learners an opportunity to develop concepts and acquire the manipulative, creative and high-order thinking skills. The integration of Information and Communications Technology (ICT) utilizing different digital learning resources and learning technologies paved the way to enhance the teaching and learning of Science and Health. Hence, teachers handling Science and Health in Grades III to Grade VI could create 21st Century learners who are globally competitive.
  3. 3. SCIENCE AND HEALTH DESCRIPTION Science and Health aims to help the Filipino child gain a functional understanding of science concepts and principles linked with real life situations, acquire science skills as well as scientific attitudes and values needed in solving everyday problems. These pertain to health and sanitation, nutrition, food production, and the environment and its conservation. There is no Science and Health for Grades I and II but simple science and health concepts which include the child’s interaction to his immediate environment are contents of English. These concepts reinforce the sensory-perceptual activities introduced in the 8-week ECD Curriculum. Likewise, process skills may be developed in Makabayan subject like Sibika at Kultura. Teaching Science and Health will formally start in Grade III using English as medium of instruction. In Grades IV-VI, more complex study of Science concepts will be taken up in preparation for High School work. TIME ALLOTMENT Learning Areas Daily Time Allotment I II III IV V VI Science and Health (integrated in English for Grades I & II) - - 40 60 60 60 Science and Health for Grades I and II is integrated in English. This is used as vehicle in developing the skills in English. Grade III is given a 40-minute daily time allotment. In Grades IV, V and VI, there is an increase of 20 minutes in the daily time allotment, to give more time and emphasis on the study of Science concepts and processes.
  4. 4. NOTE TO TEACHERS The Philippine Elementary Learning Competencies (PELC) in Science and Health serve as a continuum in teaching the subject from Grade III to Grade VI. This seeks to address the needs of pupils by conducting learner-oriented and experiment – based activities applying inquiry approach and make teaching more interactive, collaborative, integrative, and discourse-oriented to produce reflective learners. Learning competencies cover understanding of concepts and key principles of science, science process skills, and desirable values to make the students scientifically literate, productive and effective citizens. The competencies promote the use of Higher-Order Thinking Skills (HOTS), life skills and multiple intelligences as supported by the developed Lesson Guides which serve as guide for teachers. Our dear teachers, you have the options and opportunity to teach Science and Health in a more enjoyable, interesting, productive, fun-filled, fulfilling and more meaningful way. Models of teaching such as inquiry training and concept attainment, teach students the process of investigating and explaining natural phenomena, compare and contrast supplementary activity books and work textbooks that contain the attribute of the concepts. The development of process skills such as observing, inferring, predicting, classifying, communicating, measuring, formulating hypothesis, controlling variables, experimenting, gathering and interpreting of results in terms of models and prediction for the future based on generalizations. The development of the scientific method through hands on and minds on activities using these processes are conducted to compliment and probe any concept learned or can be learned. This is so, because science is both a process of inquiry and a body of knowledge. Different teaching strategies should also apply to capture the pupils’ attention and increase their interest more. You are also encourage to integrate the available digital learning resources such as CD-ROM based materials, online resources and other digital resources that are suited and within the level of the learners. The use of learning technologies such as Computer aided language learning software, Office applications (Word, PowerPoint etc), the Internet, DVD players and mobile phones play an important role to support the teaching-learning process and strengthen concepts learned. Finally, it is advised that some competencies be taught in advance as scheduled due to occurrence of destructive phenomena and events in the country. The examples of these are weather-related lessons, climate change, prevention of water-borne diseases and animal-related diseases, waste management and others..
  5. 5. GOAL: Construct knowledge and understanding of science and health concepts, develop the skill for scientific inquiry, solving problems, communicating scientific ideas and results and for making informed decisions and develop attitudes and values that would benefit themselves, society and the environment GOAL: Translating knowledge into new context of Science and Health concepts, developing opinions, judgment or decisions, solving problems using required skills, relating scientific ideas, verifying values of evidence and assessing value of theories.
