Trang 3Essential Natural Science
Essential Natural Science is a four-level course which teaches the core curricular
objectives of Natural Science to students aged 12 to 16 Drawing on recent progress
in the field of CLIL (Content and Language Integrated Learning), the course hasbeen designed as an effective, user-friendly tool in the classroom Its goal is tocombine scientific accuracy with clarity of presentation and simplicity of language
Research tasks and stimulating activities help learners to develop valuable skills and to reflect on the learning process
Every opportunity has been taken to personalise the contents so that young learnersdevelop scientific curiosity, as well as responsibility for the world they live in
Special attention has been paid to the following aspects:
• Sequencing of contents
• Level of difficulty in both
the explanations and the activities
• Quantity and diversity
of the activities
• Quality of the illustrations
and visual explanations
• Level of English used
throughout the course
Trang 4• The telescope
• The optical microscope
• Other scientific instruments: the stereoscopic microscope, weather instruments
• An introduction to the Periodic Table of Elements
UNIT ORGANISATION
The fourteen units are organised in the same way:
Learning block I The Universe and the Solar System; the Earth
Learning block II Living beings: invertebrates, vertebrates, microorganisms
Learning block III Materials that make up the Earth: the atmosphere, the hydrosphere, minerals and rocks
Learning block IV The chemical study of material: matter, molecules and atoms
Introductory page What do you remember?: photographs with questions to stimulate recall
of prior knowledgeContent objectives: scientific learning objectivesKey language: a summary of the key language structures and functionsused throughout the unit
Unit development The main theme is divided into sections
Each section answers the title question and develops the concepts in detailActivities on the page ensure reinforcement and extension practice of bothscientific concepts and language
Hands on One page of practical activities to carry out in the classroom (or the
laboratory if available)
Activity page One page of round-up activities for revision and extension
Unit summary: What should you know? A summary of the key concepts, also recorded on the Student’s CD
Trang 5Language support
Meticulous language support throughout Essential Natural Science reflects the fact that Science is being taught in English, and English through Science
• Key language focuses attention on structures and functions that appear
regularly in the unit
• Activities are often accompanied by word or sentence prompts as guidance.
• The Vocabulary appendix groups terms from each unit with a brief
definition See pages 160 - 163
• The Key language appendix offers more language models See pages
164 - 167
• Pronunciation can be practised by listening to the recording of the unit
summary, What should you know? provided on the Student’s CD
Classroom techniques
UNIT INTRODUCTORY PAGE
To take maximum advantage of this page, use some of these techniques:
• Photographs and questions Focus attention on the photo/s and ask:
What does this photo represent? If students answer in L1, rephrase their answers in English: Yes, it’s a photo of / it represents…
• Read the title and ask: How is the photo related to the title? Make sure
you rephrase all the answers in English
• Help activate prior knowledge by creating a word map on the board
Elicit words or phrases directly related to the theme of the unit
• Introduce each of the three introductory sections separately.
What do you remember?
• Read the questions aloud, then students work in pairs or groups to answer.
• Encourage students to share and compare their responses: Let’s share
information for question 1 Do you remember anything about from previouscourses? Can you name other things that belong to this group? etc
• Add new vocabulary contributed by the class to the word map on the board.
Trang 6Content objectives
• Read and explain the content objectives Encourage learners to predict what
they will learn: What do you think we will discover with regard to the firstobjective? Give priority to the content of the students’ predictions rather thanthe correctness of their English
Key language
• Read the headings and examples aloud Ask
students if they can provide more examples:
Can you make other sentences like these?
• Turn to the Key language section at the end of
the book Students will find new examples oflanguage functions for each unit
LEAD-INS
Devise a variety of lead-ins (short activities at the beginning of the lesson)
Create a file with the more successful ones and use them every day with books closed.Some practical suggestions:
• Use simple ‘true or false’ statements to focus attention on a new topic,
for example: Plants and fungi belong to the same kingdom True or false?All rocks are solid True or false?
• Do quick hand counts to assess how much practical experience students have:
Put up your hand if you have ever seen an eclipse; visited a planetarium …Count the hands and present conclusions: Most students have (never) visited
a planetarium
• Carry out a demonstration or quick experiment and ask a question about it:
What happens when I drop (a plastic bottle / a rubber ball) on the floor?
What would happen if I dropped (a glass bottle)?
• Do ‘brain gym’: write the letters H I J K L M N O and tell students they
represent the word ‘water’ (H to O or H2O); What is 2 and 2? (4 or 22)
• Brainstorming: Find three scientific terms beginning with the letter ‘s’.
Say the names of the planets in alphabetical order, etc
• Use the Vocabulary organiser, provided on the Student’s and Class CDs
Write a scientific term on the board and ask individual students what it means
in L1, how to pronounce it and what visual and written association they mightgive it
• Arouse students’ curiosity: cover a shoe box with attractive paper and keep it
in the classroom Put interesting specimens, related to the content of the day’slesson, into the box (rocks, a leaf, an insect, etc.) Invite students to guess whatthe specimen might be: What’s in my mystery box today? Encourage students
to provide specimens as well
Trang 7UNIT DEVELOPMENT PAGES
Most units contain between 6 and 8 sections
Each section begins with a numbered scientificquestion to be answered and developed in various sub-sections Highly effective visuals accompanythe texts, and the key vocabulary is highlighted
in bold
Did you know that…? boxes provide interestingadditional information related to some of the maintexts
The majority of the content pages feature anActivities box Students carry out the tasks directlyrelated to the content of the section, or do
supplementary research on the topic
Before reading
Whenever introducing a new section, use some of these techniques
to aid reading comprehension Read Essential Natural Science, page 64,
to follow this explanation
• Presentation: Read the section number and
question aloud For example, Two What are non-flowering plants like? Brainstorm possibleanswers If reading out a yes / no question, forexample, Can plants react?, students predictwhat the answer might be
• Skimming: Ask a general question about the
section: How many types of non-floweringplants are there? The bold words in the firstparagraph, the headings of the two sub-sections that follow, as well as the drawings,provide an immediate answer: Two Ask:
What are they? and elicit the answer:
Mosses and ferns This helps studentsbecome familiar with how the information
is structured and presented
• Scanning: Copy an incomplete sentence or definition from a section on the
board Students complete it with the appropriate word, for example: Mossesproduce inside capsules Or, ask a question that students cananswer by looking at the text more closely: Where do spores grow? This helpsstudents focus on specific information
• Focus on key vocabulary: Draw attention to the words in bold, then ask
students to refer to the Key vocabulary on pages 160 -163 to find somedefinitions Encourage them to complete the Vocabulary organiser for eachunit (See Vocabulary organiser, page 9.)
Trang 8• Focus on Key language: Ask: Can you find any examples of the key language
here? Students refer back to the introductory page, then scan the text again tofind examples They copy the functions in their notebooks and colour-codeboth the functions and the grammar points to improve recall:
Comparing – Ferns are bigger thanmosses
Making generalisations – Most gymnosperms are evergreens
While reading
• Specific task: Students read the page individually or in pairs to complete
a task, for example, finding a definition or answering a specific question
• General task: Ask students to find the main idea in the text.
After reading
• Students can be asked to summarise the text orally, or in writing, especially if
it describes a process or transmits an opinion
• They can also read the text again and write down key facts in note form:
Mosses: non-flowering, non-vascular plants No true roots, stems or leaves…
ILLUSTRATIONS
The illustrations in Essential Natural Science include high-quality photographs,drawings, maps, charts and diagrams with captions which provide explanations and / or additional information The drawings illustrate states or conditions thatcannot be represented with photos, such as processes They are labelled to providestudents with essential key vocabulary
The illustrations in the Student’s Book satisfy the following criteria:
• Quality: chosen for their clarity and level of detail
• Representativeness: the best-known and most frequent examples are shown
• Ease of identification: all the necessary references are provided
EXPLOITING THE ILLUSTRATIONS
Depending on the type, an illustration can be used to help students quickly grasp
a complex idea or set of data, describe a situation or a process, predict an outcome,support an explanation or develop observation skills and attention to detail
Do the following activities:
• Make sure students know the meaning of these terms: diagram, close-up,
magnified image, cross-section, graph, bar graph, pie chart and table Theyshould use the correct term when describing an illustration
Trang 9•
• Identify the type of illustration and say what it represents:This is a (cross-section)
of (a snail) This (pie chart) shows the percentages of organic and inorganic substances in plants
•
• Focus attention on the caption and read it aloud, then help students rewordthe information: The pie-chart shows the percentages of organic and inorganicsubstances in plants
•
• Read the labels that flag the different parts of the illustration and make surestudents know how to pronounce the words They may add new words to theirVocabulary organiser for the unit

AC CT TIIV VIIT TIIE ES S
Activities throughout the unit provide exercises to help students analyse, revise,extend and summarise the new concepts There are several different types:
•
• GGllooball ccoommpprreehennssiioonn aaccttiivviittiieess These include questions to help studentsclarify concepts, compare elements by describing similarities and differences,describe the outcome of experiments, draw inferences from known facts,
or use logic to solve problems These questions require a degree of linguisticcompetence on the student’s part Encourage them to consult the Keylanguage boxes and the Vocabulary and Key language sections at the end
of the book
•
• AAccttiivviittiieess bbaasseedd oonn iilllluussttrraattiioonnss These involve observing or producing
a drawing, a diagram, a graph or a chart Remind students that clear,uncluttered pages and neat labelling are essential, and spelling should always
be double-checked
•
• AAccttiivviittiieess bbaasseedd oonn rreesseeaarrcchh These aim is to help develop research skills andskill in collecting, selecting and representing information gathered fromdifferent sources, such as encyclopedias, books, specialised publications andthe Internet Students can work in groups, especially to produce the end ofunit Web task Encourage them to create multi-media presentations to show
salts 3.2 %
Trang 10HANDS ON
• One page per unit provides a practical activity designed to foster scientific
skills Some of these activities can substitute for work in a Science laboratory,
or, indeed be carried out in a laboratory The activities have been chosen
so that students acquire scientific methodology and observational skills and become familiar with scientific procedures
• The experiments are safe, easy to set up and do not require complicated,
expensive materials The methodology can be studied without performing the experiments at all
• The Hands on activities encourage students to apply the knowledge they
have acquired to the comprehension of the world around them
WHAT SHOULD YOU KNOW?
• The end-of-unit summary synthesizes the most important concepts which
have been taught, providing a concise overview This summary is recorded
on the Student’s CD and can be used for revision and additional oral andpronunciation practice
• What should you know? pages are ideal as revision sheets, to be studied
before the Unit test, or before main exams
The track number is supplied on the CD icon:
PROJECTS
• Each unit summary is followed by one or two Projects in which students can
relate science to technology, society, and the environment If done in pairs
or groups, the projects will ensure more varied input and help students develop strategies for successful team work, such as delegating, sharing and negotiating
STUDENT’S CD
The Student’s CD provides the following resources:
• Audio tracks The unit summaries What should you know? can be used either
in class or by the students at home to revise the content of the unit and topractise the pronunciation of key vocabulary and expressions
• Web tasks: one, sometimes two, per unit Each task poses a question to solve,
together with several pre-selected links to the Internet Web tasks are research tasks: students are instructed to go to selected web pages to find theinformation they need They then represent the results in the form of reports,graphs, posters, etc They can be done individually, in pairs or in groups
mini-• Activity sheets Blank diagrams for students to use to revise the key unit
vocabulary There are between two and four per unit They can be printed outand completed individually or in pairs

Trang 11• Vocabulary organiser: Students can print out the template and complete it with
key vocabulary as they work through a unit Explain the layout at the beginning
of the course:
– One organiser or more for each unit Students print out as many as they need
– Each sheet is divided into five columns: students write the English word inthe first column; the translation in L1 in the second; the pronunciation in thethird column The fourth and fifth columns are optional: in Visual
association, students draw or doodle whatever helps them visually recall theword In Written association, students can write anything that will help themmemorise the word: a play on words, a word set, etc Encourage them to usecolour on these sheets to highlight important information or words they havedifficulty remembering
– These sheets should be filed with the worksheets and activity sheets

Trang 12Teacher’s Resource Pack
The Teacher’s Resource Pack provides the following material for each unit:
1 UNIT INTRODUCTION AND PROGRAMMING
This double page includes the objectives and contents as well as the assessmentcriteria (expressed as ‘Can-do’ statements) for each unit A list of the competencesthe students are expected to develop is provided, as well as the activities related
to each competence
2 REVISION, EXTENSION AND ASSESSMENT WORKSHEETS
There are five worksheets per unit
• Worksheets 1 and 2 Word games and simple exercises recycle and revise the
vocabulary, key language and structures of the unit
• Worksheets 3 and 4 A variety of exercises: jigsaw tables and charts, word
maps, question loops, etc., to revise both the scientific content and the keylanguage of the unit Worksheet 4 is designed as an interactive activity for pairs
or groups
• Worksheet 5 This provides an optional reading passage as an extension
activity More challenging in language level than in Essential Natural Science
in general, it develops one of the central themes of the unit, followed bycomprehension questions and exercises Use Worksheet 5 essentially for the more advanced students
Exploitation of worksheets
• A score box is included on each worksheet Students can mark each other’s
work in class In this way, they will know immediately how well they have done and which areas they still need to work on The answer key is provided
on the Teacher’s CD
• These worksheets are flexible and can be used at any point during the lesson,
as a quick test of what has just been presented, as extra preparation for theUnit test or to be done as homework They address the need for diversity in the classroom: to revise and / or extend both the scientific contents as well
as the language structures They are designed to be completed individually,but challenged students may gain from working with a partner
• The worksheets should be photocopied as required Hand them out and read
out the instructions Students may find coloured pencils or fluorescent markersuseful to highlight details
• The worksheets can be filed in a folder and used for revision when needed.
Trang 13The Class CD includes all the material on the Student’s CD and in addition:
• Answer key: Answers for all the activities in the Student’s Book, as well as
the answers to the Worksheets and activity sheets
• Audio material: One task listening per unit, usually identifying, saying True
or False or classifying This provides excellent aural practice for students and can be used in different ways, for example, asking students to summarisewhat they have heard in writing, take notes while they are listening or listen toall the questions before answering them rather than giving an answer afterevery question
Trang 14The Class CD provides 14 PowerPoint presentations, one for each unit in EEsssseennttiiaallN

Trang 15Webquests combine individual and group work, so the students work together andlearn through cooperation They provide:
• Motivation Most students enjoy working with computers and find it motivating.
Webquests pose problems which inspire curiosity and a desire to find answers
• Skills development Finding and selecting information, synthesis
or analysis Students also learn to develop their own criteria and draw their own conclusions
• Personalisation Webquests allow students to work in a more personalised way.
Organisation
The Webquests have five parts:
1 Introduction This gives the student basic information about the proposed
activity It creates interest and curiosity about the subject to be researched
2 The task This section explains what the student is expected to do Tasks can
vary: creation of a webpage, a report, or a brochure, an oral presentation, adramatisation, a role-play, etc
3 The process This stage describes the steps the student should follow in order
to carry out the task successfully All the links are provided in order to obtainthe necessary information, and are clearly connected to the questions asked
The Webquests provide all the sources of information needed, such as webpages, documents…
4 Evaluation This comes at the end of the process when the task has been
completed A table of assessment is supplied which can assess content, finaloutcome, and personal involvement of the student in carrying out the task
This type of assessment has its advantages: the students know what isexpected of them at every stage which helps them to focus on their task
They can also assess themselves and so become aware of their own learning process
5 The conclusion The final stage of the task gives students the opportunity
to reflect on their work and what they have learned It also provides anopportunity to correct possible errors and improve the Webquest
Trang 16THE WEBQUESTS IN ESSENTIAL NATURAL SCIENCE
There are three webquests, linked to the contents of Essential Natural Science Theyprovide an alternative, less conventional way of studying aspects of the syllabus
1 Our future home The exploration of the planets and a comparison with Earth.
To accompany Units 1 and 2 of the Student’s Book
2 Paradise corner Ways to preserve the animal and plant world To accompany
Units 3 - 6 of the Student’s Book
3 A journey to the wonders of nature The exploration of beautiful places on
Earth To accompany Units 9 and 11 of the Student’s Book
All three Webquests require both group and individual work
EXPLOITING THE WEBQUESTS
Before starting
• Explain the different sections and talk about the general organisation of the
Webquest: the topic, group formation and the roles of its members, the timethey have to do the task and the final outcome If necessary, they can writedown the purpose of the task so they can refer to it
• Focus the students’ attention on the task and awaken their interest in the
subject: read a fragment of a relevant book, show part of a film, etc
Collecting information
• The students have a variety of sources at their disposal and they have to select
those which are relevant They should analyse the information and decide if it isuseful Advise them to print out only useful information
• As students collect information, they can organise it by creating a rough
version
• They may need to collect pictures or recorded material to finish their task.
• Finally, explain the importance of communicating findings to the group.
Processing information
• Remind students that they should synthesize the information obtained,
keeping in mind how they are going to communicate it later
• Explain the importance of editing the information: they should write correctly
and make any necessary corrections
Communicating the information
• Tell the students that they should express clearly their main ideas.
• Explain that they should keep in mind their audience and the format they are
required to use
Trang 17Natural Science, the topics presented for discussion include the need for adequate
eye protection when observing eclipses, the dangers of antibiotics abuse, thedangers posed to health by certain industries, protection against harmful radiations(Health Education), as well as conservation of the Earth’s biological resources, theimportance of invertebrates in the food chain, poaching and illegal animal trade, thecontrol of pests by natural means, the development of responsible consumer habits,and the need to reduce water consumption (Protection of the Environment)
The Introduction to each unit provides examples for discussing the values related tothe theme
KEY COMPETENCES
Competence is the capacity to use one’s acquired knowledge, abilities and personal
attitudes in different contexts and situations
Key competences feature the following characteristics:
• They focus on the development of abilities rather than the assimilation of
theoretical content: individuals become ‘competent’ when they learn how tosolve problems effectively
• They are dynamic because they develop progressively and can be acquired
in different learning situations and institutions
• They are interdisciplinary and transversal because they integrate knowledge
that originates in different academic disciplines
• Once acquired, they will become part of the student’s lifelong learning
experience
Reasons for including key competences in the secondary curriculum
• They integrate formal and informal learning experiences.
• They allow students to use their skills in widely differing contexts.
• They help clarify objectives, content and assessment criteria in all
the subjects
• Each area can contribute to the development of key competences which
are then applied to other areas or subjects
Trang 18THE EIGHT KEY COMPETENCES
The following key competences are considered necessary and should be developed in all the subjects of the curriculum
Competence in linguistic communication
The use of language as a tool for oral and written communication
Mathematical competence
The ability to use numbers, perform basic operations and understand the symbols and forms of mathematical reasoning
Knowledge and interaction with the physical world
The ability to interact with the physical world and apply the scientific method
to explain its phenomena
Processing information and digital competence
The ability to find, obtain, process and transmit information using traditional and modern technologies
Social competence and citizenship
The ability to understand the social reality in which we live and the desire
to contribute to its development
Cultural and artistic competence
The appreciation of cultural and artistic manifestations through the ages and in different cultures
Competence in ‘learning to learn’
The ability to plan courses of action and set oneself goals in order to developefficiency and autonomy during the lifelong learning process
Autonomy and personal initiative
The ability to imagine, develop and evaluate individual or collective projectscreatively, self-confidently and with critical sense
Trang 19• Knowledge and interaction with the physical world
Knowledge of the physical world is the basis of all Science Scientific knowledgeintegrates strategies in order to learn how to define and solve problems, designexperiments, analyse results and communicate them Knowledge of one’s ownbody and caring for one’s health are also crucial in the acquisition of thiscompetence, as are the interrelations of people and their environment
• Digital competence: using new technologies
The ability to select and use information found in digital media involves textprocessing (copying, pasting, inserting images,…) and surfing the Internet
Students become familiar with the different codes and formats of scientificlanguage (numerical and geometrical models, graphic representations, statistics,chemical symbols, etc.)
• Social competence and citizenship
This competence helps develop group cooperation, solidarity and satisfaction atcompleting given tasks Scientific literacy constitutes a fundamental dimension ofcitizen culture, allowing students to form opinions based on solid data with regard
to problems related to scientific and technological progress
• Cultural and artistic competence
This area deals with the ability to produce accurate and elegant models torepresent scientific facts and results It also highlights the contribution of scienceand technology to the development of humanity’s cultural and artistic patrimony
• ‘Learning to learn’
Operating with theoretical models helps develop imagination, powers of analysisand observation skills, creativity and a critical attitude, which in turn fostersautonomous learning
• Personal initiative
The study of Science demands autonomy and initiative From the moment ahypothesis is formulated until conclusions are reached, students need to selecttheir resources, plan the methodology, solve problems, manage their resourcesand constantly revise their results

EVALUATION CRITERIA
A look at astrology and its historic links with science
and religion Astrology asserts that the position of
certain stars and planets influence our personality,
important events in our lives and even our destiny
Astrology as we know it originated in Babylon over
5,000 years ago as a compound of religion and
science The scientific part was concerned with
the movement of stars, whilst the religious partattempted to determine the relationship betweencosmic events and happenings on Earth As humanknowledge increased, astrology was separated fromthe science of astronomy and relegated by scientists
as superstition

a shield For some strange reason, the moons of Mars received Greek names ratherthan Latin ones, Phobos meaning ‘panic’ and Deimos meaning ‘terror’, because thesetwo feelings are always related to war
Phobos can be used as a suffix We can construct words that inform us about humanand animal feelings of extreme fear in different situations For example,
a person who suffers from claustrophobia feels terribly afraid when enclosed
in a small space Think also about other similar words such as hydrophobia,arachnophobia or agoraphobia There are all kinds of fears! Fortunately, as rationalhuman beings, we can also use different strategies to overcome these fears

Theories of the Universe
In the second century BC, the astronomer Ptolemy proposed that the Earthwas the centre of the Universe, and that the Sun, Moon and planets orbitedthe Earth This was known as the Geocentric theory, or the PtolemaicSystem However, in 1542, Nicolas Copernicus proposed that the Sun was
at the centre of the Universe When Galileo Galilei invented the telescope in
1610, he was able to prove the Heliocentric theory (or Copernican System):
the planets and stars revolve around the Sun

Students should understand that it is vital to protect
their eyes while observing solar eclipses Looking
at the Sun without adequate protection can result
in serious, irreversible ocular lesions and even
blindness Protection must be used from the beginning
to the end of the eclipse and eyes averted from the
Sun frequently
Eclipses can be observed through special glasses
available in pharmacies or at an optician’s, or using
welding glass nº 14 as a filter Special filters can beused in telescopes
Eclipses can also be observed through a camera obscura
or by projecting solar light through a telescope andfocusing the image on a screen The Sun must never beobserved through optical instruments without appropriatefilters The following should not be used as filters: smokedlenses, developed film, strips of semi-transparent plastic,sunglasses or binoculars with solar observation glasses

Trang 34Does Earth have a twin?
There is a planet in the Solar System which is completely covered in thick clouds It has a volcanic surface and a poisonous atmosphere
Its average temperature is 480 ºC, while on Earth the average temperature is 15 ºC Its clouds contain sulphuric acid rather than water
It cannot possibly support life! Yet for years scientists have consideredthis planet as Earth’s twin
Why?
Firstly, it is similar in size and mass to Earth Both planets are very close
to each other, much closer than any other pair of planets Both are quite young geologically (They have very few craters caused by meteorite impacts on their surfaces)
In the beginning, the Earth’s twin probably had oceans Then, the oceans turned into desert land as the water disappeared This was due to the accumulation of carbon dioxide in its atmosphere (On Earth, this is known as the greenhouse effect!)
Finally this planet, named after the Roman goddess of love and beauty, has a variety of geographical features similar to those on Earth
These include plains (about 65 % of the surface), mountains, canyons, and valleys
If this is enough to consider the mysterious planet ‘Earth’s twin’, imagine how incredibly different all the other planets must be from ours!

The Earth
Some specific characteristics make the Earth a unique planet in the Solar System
In the first place, it has an atmosphere containing 1 1 which is essential for plant and animal respiration The Earth’s atmosphere also contains carbon dioxide which
is essential for 2 2 It also has a 3 3 cycle and an average
temperature of 4 4 The Earth’s 5 5 field protects living beings from dangerous solar radiations For all of these reasons, the necessary conditions for life exist
on our planet
