Foreword:
By Dr Chamrat Nongmak
When talking about bilingual education in private elementary - and secondary
schools in Thailand, the discussion invariably tends to focus on Sarasas Affiliated
Schools, a large group of private schools that were formerly owned and administered by
the late Mr Piboon Yongkamol. Mr Piboon, a well-known and respected educator, was
a leading pioneer of the bilingual education concept here in Thailand. These schools
provide a benchmark and a showcase for bilingual education in Thailand. Many school
proprietors, directors, and managers make it a point to visit Sarasas Affiliated Schools
seeking advice and guidance from a successful leader in the field of bilingual education.
Sarasas programmes for teaching students in both English and Thai have been
carefully planned and developed step by step. One of the toughest challenges Sarasas
has had to face has been finding the necessary texts and materials for teaching Thai
subjects in English. This is because a bilingual school, like any other Thai school,
needs government approval to operate and must teach the curriculum mandated by the
Ministry of Education. Unfortunately, the materials needed for teaching Thai subjects in
English are not readily available. Publishers do little to support this need because the
concept is still fairly new, and the demand is small. This has forced Sarasas to create its
own texts and materials.
Sarasas has been more fortunate than most other schools struggling to develop
their own bilingual program. It already has bilingual education experience, qualified
staff, and the resources necessary to produce its own high-quality textbooks and
materials. The staff, of course, is the most important ingredient.
Sarasas’ large, well-seasoned staff of highly competent, well qualified and dedicated
teaching professionals, both Thai and native speakers of English, gives it a unique
advantage over others attempting to produce these much-needed materials.
Even so, it has not been an easy task. The materials have been produced through
the careful process of research and development. The revision or total change is done
when those materials are proven to be inadequate. The people involved in developing
these textbooks or workbooks are classroom teachers. They are the ones who will have
to teach with the same materials they have helped to create. Knowing this gives them a
greater incentive to do it right.
The teams of classroom teachers responsible for classroom material development
operate under the close supervision of the Sarasas Board of Executives.

One of the roles of the board is to assure proper quality control by collecting and
carefully evaluating the actual work done by students using the new materials. They
ensure that the students are able to understand the material and use them effectively.
One of the things they check for is whether the level of English used in the books is
appropriate for the students’ level of English. The board also makes certain that the
content of the material is in accordance with the approved syllabus. This science book
has been developed through this process.
This book is not only useful for teachers but also for parents and guardians.
Its purpose is to encourage and support students in their quest for knowledge and
understanding of science, as well as stimulate their interest and improve their skills.
Each unit provides an introduction to the material, a list of new words the student will
encounter, problem-solving examples to help the student better understand how to do
the work, oral exercises, and a review of what was learnt.
This new science material will provide students with a greater international
perspective and understanding of Science and Scientific terminology, which will benefit
them greatly in later life. This said I would like to take this opportunity to thank those
responsible for developing this material and offer my sincere congratulations for a job
well done.

PREFACE

This Science textbook has been developed for bilingual learners based on the
B.E. 2560 (A.D. 2017) revised version of Thailand’s Basic Education Core Curriculum
B.E. 2551 (A.D. 2008). The content of this book goes along with The Basic Science for
Primary 3 Book 1 written by The Institute of Academic Development.
This textbook aims to enhance students’ skills needed in the 21st century, which
include analytical skill, problem solving skill, creativity, and collaboration skill.
Each unit in this textbook provides vocabularies that are useful to learners at the
beginning of each unit. Examples that show students how to apply what they have learnt
to solve related problems. Followed by exercises that are similar questions provided
for immediate practice. At the end of each unit, a summary of the key concepts and a
revision exercise is provided to help students consolidate what they have learnt.

Like humans and plants, animals need water to sustain life.
It is an essential component of their body. Animals need to drink
water for use in various processes. Some animals also rely on
water as their habitat and use it as a food source.

Some animals such as shrimps, crabs, fish, seahorses, whales,
dolphins, seals and sea lions live in water.
Some animals find their food from different water sources.
Some birds catch fish for their food.
All living things must have water to survive. If an animal doesn't
