Preface Harmony Teacher’s Resource Pack is enriched with detailed information about the scheme of Continuous and Comprehensive Evaluation (CCE), principles and class-room strategies for the assessments in scholastic and co-scholastic areas, along with the tools and techniques of evaluation in those domains. It focuses on the teachers’ communicating the feedback to students thereby making the assessment process more productive and result-oriented. New learning is to be developed based on what students already know or understand. Since students respond differently in different situations, teacher’s formal or informal feedback helps them immensely in improving their learning skill.Environmental studies(EVS) comprises various branches of studies like chemistry, physics, life science, agriculture, public health, social studies, etc. The objective of Environmental Studies is • to increase public awareness about environmental issues, • to make wise and rational use of natural resources,• to maintain, protect and improve the quality of environment, and• to lay the foundation for a fully informed and active participation of individual in
the protection of environment. Through EVS, students will learn real-time knowledge and skills which are required while dealing with the environmental problems and searching for possible solutions. Teacher plays a major role in helping students learn Environmental Studies as a con-cept and not merely as a subject. She/He motivates students to use their senses in ex-ploring their surroundings to respond naturally and sensibly. Today’s student needs to know not only the basic reading and arithmetic skills, but also skills that will allow him/her to face a world that is continually changing. All students must be able to think critically about an environmental problem, analyse it in the social perspective and make inferences that help them to respond effectively.
IntroductionHarmony series enables the learner to be in harmony with life and the environment. Harmony Teacher’s Resource Pack is a set of five books for classes 1 to 5. Each pack of this set helps the teacher to make the teaching-learning session interactive and interesting. It emphasises on regular assessments, frequent unit testing, identification and tries to encourage non-participative students in the classroom activities. More importantly, it diagnoses the learning gaps and adopts corrective measures.
It comprises• a complete teaching-learning session with overall aims, methods, strategies, techniques and
assessments to meet the different needs of children.• a concise note on assessment, as it is perceived to be an integral part of the teaching-learning
process.• an overall lesson plan that helps the teacher to assess the outcomes.• a detailed lesson plan with effective teaching techniques—like the required teaching aids,
introduction, presentation of the lessons, and sufficient activities. • worksheets and their answers, and answers to coursebook exercises.
Salient features of Harmony series–• Warm-up activity or pre-teaching links the known to the unknown at the beginning of each
chapter.• Do You Know? imparts nuggets of extra learning and facts.• In-text Questions to provide assessment to learning and aid introspection.• In-text Activities to assess ‘what I have learnt so far’.• Summative & Formative Assessment covers many tools and techniques recommended
by the CCE aimed at consolidating learning and the application of it.• Let’s think probes higher order thinking skills (HOTS).• Life Skills steer all learnings towards rooting it in life.• Teacher’s Tip serves as a little guideline to the teacher on how to transact learning.• Test papers are provided for both Summative and Formative Assessments.• Problem Solving Assessment helps develop soft skills for holistic development.• Value Based Questions as a case study or activity per chapter to enhance learning.
Harmony Teacher’s Resource Pack provides the teacher with engaging and meaningful methods about putting into practice the objectives of teaching and judging students’ achievement. It is continuous because it occurs over a period of time, and comprehensive because it covers both scholastic and co-scholastic aspects of students’ overall learning and development.

Assessment
Continuous and Comprehensive Evaluation (CCE) assesses children continuously and comprehensively through various tools and techniques. Its purpose is diagnosis, feedback, remediation, and effectiveness.
Continuous
This refers to the regularity in assessment, i.e., assessment integrated while teaching. Assessment should be done both in formal setting (inside the classroom) and informal setting (in the computer lab).
Comprehensive
This refers to the application of a variety of tools and techniques (both testing and non-testing) and aims at assessing a learner’s development in areas of learning such as:
• Knowledge • Analyzing• Understanding • Evaluating • Applying • Creating
Evaluation
Formative Assessment
This continuously assesses children in everyday learning situation during teaching. It helps the teachers to diagnose learning gaps in children and acts as feedback to the teachers to take remedial action immediately.
Summative Assessment
This sums up how much the children have learned at the end of teaching. The tools and techniques used are:
• Objective type • Very short answer type• Short answer type • Long answer type
Tools
• Questions • Observation• Document analysis • Tests and inventories• Self-assessment • Peer assessment
Techniques
• Examination • Assignments• Quizzes • Competition• Projects • Research work• Group discussion • Hands-on experience• Group activities • Survey
CCE Implementation in Harmony
Summative Assessment
Simple and interesting exercises based on the text to enhance
the understanding of the concept.
Formative Assessment
Includes activities and questions that initiate learning, develop thinking skills, and enable the learner to practically apply the
concepts learnt.
Skills assessed are remembering, understanding and implementing what the child has learnt.
Tools used are Short answer and Long answer type questions.
The techniques used are Internet surfi ng, Project work, Group discussion, Research work.
Skills assessed are remembering and understanding.
Tools used are MCQs, Match the following, Fill in the blanks, True or false, Short answer and Long answer type questions.
The technique used are Examination, Exercise, Worksheet.
Assessment is considered to be an integral part of learning which is ‘continuous’ and ‘comprehensive’.An overview of CCE and its implementation
(vi)
In order to understand assessment, all aspects of learning are covered. A suggested list of skills and parameters for assessment at the primary level of schooling is given below to help the teacher to arrive at a comprehensive picture of the students’ learning. Manners and modalities, however, may vary.
EVS/ScienceAspects Parameters/Techniques
Understanding of concepts Oral tests, drawing pictures, paper-pencil tests
Environmental sensitivity Understanding the need to care for the environment
Experiment / Activity / Project work Understanding of concepts, participation, interest, level of involvement, cooperation, attitude towards peers, application of knowledge gained to prepare charts and constructive models
Scientific skills Ability to observe, reason, enquire, explore, debate, apply, reflect and formulate solutions
Group discussion Clarity of thought, confidence, expression of opinion; voice modulation
Written work Neatness, clarity of thought, ability to draw neatly labelled pictures/diagrams, logical flow of text
Assessing Co-scholastic areasLife Skills have been chosen by CBSE as one of the co-scholastic areas. They are abilities for adaptive and positive behaviour that enable individuals to deal effectively with the demands and challenges of everyday life. Learning and practising Life Skills help students to improve their personal and social qualities. The Life Skills prescribed by CBSE have been included followed by different tools and techniques—some of them are practising humility, caring for animals, caring for environment, showing respect to elders etc.Harmony is in complete harmony with life skills, values and attitudes.

D 1. Birds of prey have binocular vision. they can see things clearly from a distance of eight metres.
2. an owl can easily detect the movement of a mouse across snow or burrowing through leaves. the owls have one ear opening slightly higher and larger than the other. Sounds reach one ear a split second before the other to allow the owl to judge accurately the distance and position of the sound’s source.
3. the chemical substances that are produced and secreted by ants, are called pheromones. 4. Some animals use facial expressions to communicate, e.g., wolves and chimpanzees show
expressions of fear, anger or excitement. Some animals use sound signals to warn others of danger. For example elephants and
langurs. Dolphins use sound signals to show happiness, anger or excitement. Some animals use scents to communicate with each other like lions and wolves. 5. Small animals sleep more than large animals as most of their energy is used up. Cats and
dogs also like to sleep in many short intervals. animals that are grass eaters sleep for short duration. However, they rest while chewing the cud.
Some animals sleep during daytime while some sleep at night. Water animals never sleep fully as they need to keep swimming. Insects do not appear to sleep but they do become inactive in daylight.
Some animals sleep in long sessions like sleep for the whole of winter or summer season.

plants to form seeds from which the new plants grow. Seed dispersal : Seeds of some plants spread (disperse) to distant places by sticking
to the bodies of animals and birds. Hence, animals and birds help in the dispersal of seeds.
Carbon dioxide : Plants need carbon dioxide for carrying out the process of photosynthesis.
Manure : the dead bodies of animals get decomposed in the soil. this serves as good manure for plants to grow.
(b) Dependence of Animals on plants Food : animals are dependent on plants for food directly or indirectly. Oxygen : animals depend on plants for the supply of oxygen. During photosynthesis,
plants release oxygen. this oxygen is used by animals for breathing. Shelter : Many animals depend on plants for shelter. For example, birds build their
nests on the trees. Monkeys and squirrels live on the trees. Big animals like elephants live under the trees.

3. Some of the ways of conserving of forests are as follows : (a) Conservation by Tribals : tribals have a unique way of saving plants and animals of
that area through sacred groves. a sacred grove is a vegetation area with a variety of plants. It is dedicated to a local deity or god regularly worshipped in that area.
(b) Conservation by the People :TheChipkomovementisthefinestexamplehighlightingthe effortsofpeople to save forests. ‘Chipko’means to embrace.When the timbercontractors came to cut the trees, women put their arms around the trees and refused to move. Many trees and forests were thus saved.
(c) Conservation by Private Companies : Many private companies have also come forwardtoconserve forests.Theybuyforest lands fromthegovernment.Differentkinds of trees are grown on that land such as fruit trees, coconut, rubber and sandalwood. Such forests are called orchards.
(d) Conservation by the Government : In order to protect and preserve the wide variety of plants and animals, the government has set up numerous wildlife sanctuaries, national parks and biosphere reserves.
the government celebrates many important days, such as the Earth Day, World Environment Day and Van Mahotsava. Lakhs of saplings are planted by the school children and other people all over India.
4. tribals are those people who live together as a community in forests. Each tribal communityhasitsowncultureandtraditionthataredifferentfromtheothercommuniteseven though both the communities may live in the same forest. oraons, Santhals, Gonds, Mundas and Bishnois are the tribal communities living in Bihar.

C 1. Various land reforms were introduced by the government such as : (a) the zamindari system was abolished. the land was given to the poor farmers. Now,
there were no landlords. Farmers became the owners of their land. (b) the government put a ceiling on the landholdings. It was done so that all the farmers
could have land to practise agriculture. No one could own excess land outside the permissible limits.
(c) The landholdings were consolidated by the government. Small and scatteredlandholdings were consolidated into a larger holding at one place. the land was now bigger and more productive. this is called chakbandi.
2. New varieties of pesticides do not harm the crops but they harm only the pests if used wisely. these have helped farmers to save their crops from pests, and thus get a bountiful harvest.

C 1. the food which we eat is broken down into smaller pieces and converted into soluble form. this process of breaking down of food into soluble form is called digestion.
2. there are various reasons for preserving food. Some of them are : (a) to take care of the excess produce. (b) to add variety to our meals. (c) to enable food items reach even those areas where these are not grown. (d) to make storage and transportation of food easy. 3. When food enters the stomach, these muscles expand and contract. Due to this, food is
churned. the stomach is like an elastic bag capable of holding a large amount of food. It also acts like a grinder and breaks the food into semi-solid form. the digestive juices mix the food well and break it into simpler form. Food stays here for nearly three hours.
4. Food can be preserved by various methods which are as follows : (a) Refrigeration : It is a method of keeping food at a low temperature. all food items can
be preserved by keeping them in a refrigerator. (b) Dehydration : In this method, water or moisture is removed from the food. this dried
foodcanbepreservedforalongtime.Vegetableslikepeas,mushroom,cauliflower,potato chips and papads are preserved by drying.
(c) Canning : Many fruits and vegetables are cleaned and cut into pieces. these are boiled and excess water is removed. these are sterilised and packed in sterile tins and sealed.
(d) Pasteurization : this method is used in dairies to keep milk free from micro-organisms. Milk is heated to a high temperature and then suddenly cooled. It destroys the micro-organisms present in the milk.

C 1. Fuel is a substance that burns in air to produce heat energy. For example, kerosene or LPG are used at home for cooking. Petrol and diesel are used to drive the engines in automobiles. Coal and natural gas are used to produce electricity in thermal power stations.
2. Fuelscanbeclassifiedonthebasisofthephysicalstateinwhichtheyexist.Theseareasfollows :
Solid Fuel : Fuel which exist in the solid state at room temperature, such as wood and coal.
Liquid Fuel : Fuel which exist in the liquid state at room temperature, such as petroleum, diesel and kerosene.
Gaseous Fuel : Fuel which exist in the gaseous state at room temperature, such as natural gas and gobar gas.
3. a good fuel has the following characteristics: 1. It produces a lot of heat energy on burning. 2. It does not leave behind any waste products (like ash) on burning. 3. It does not produce pollutants (like smoke) on burning. 4. It burns quickly. 5. It should be easy to transport. 4. Fuels like coal, petroleum, kerosene and natural gas take millions of years to form. these
are formed from the remains of dead animals and plants which were deposited beneath the earth millions of years ago. these got transformed into fuel due to the sun’s heat energy. these fuel are used by humans at a very fast rate so these fuel will not be available for long.
