If a doctor is prescribing some medicines to a patient and also suggesting him to eat jaggery, amla, and more green leafy vegetables. This patient must be suffering from anaemia. Anaemia is caused due to a deficiency of Iron. It is a condition in which blood lacks healthy red blood cells. Jaggery, Amla, Green leafy vegetables like spinach, kale, collard greens, dandelion greens, citrus fruits, whole grains, beans, etc. All these things are a good source of iron. 
Hence, the correct answer is, 'Anaemia.'

The teaching of EVS also helps students to develop desirable attitudes, values, and behavior patterns necessary for an environment-friendly lifestyle. A good teacher is one who has a positive attitude and whose positive attitude is reflected in the minds of students genuinely. 

Exercises and activities in an EVS textbook should be provided inbuilt in the topics as exercise and activities improve learning on three levels: "First, it optimizes child's mindset to improve attention, motivation and alertness; second, it encourages nerve cells to bind to one another and third, it encourages the development of new nerve cells from stem cells in the hippocampus." 
Hence, the correct answer is, 'Inbuilt in the topics.'

The best household method of obtaining potable water is boiling. 

EVS, at the primary stage, is an integrated subject area that draws upon insights from sciences (physical, chemical, and biological), social studies (history, geography, political science, sociology, etc), and environmental education.
Reasons for developing an integrated perspective in Environmental Studies:

• To develop an understanding of the importance and concept of the environment.
• Make children realize the importance of learning about the environment at the Primary level of education.
• To visualize appropriate learning resources from the environment and see the situation as a whole.
• To develop appropriate learning situations with a focus on interactive and experimental learning, to develop inter-related understanding among children to give them a comprehensive view of their natural environment.
• It helps children to build a relationship between the different concepts of science, social studies, and environmental education. 
• For example, while learning about civilization, the children will be able to understand the history of a civilization, its development through science and technology, and how its development affected the environment.
• For assessing learning levels, learning difficulties of each child, and design appropriate strategies for the future environment.

The textbooks should help to eradicate confusion among the students, and not to create it. The EVS textbook must help in developing curiosity, reasoning ability, and ability to think creatively.

Vitamins and minerals are very important in the human body. Sufficient vitamins are important eating too much can harm also. They are required in small quantities to prevent deficiency diseases. They help heal wounds and bolster the immune system. They also convert food into energy and repair cell injury.
Hence, the correct answer is, 'Required in small quantities to prevent deficiency diseases.'

Environmental Science (EVS) is not a new subject in our school curriculum. It is rather a new approach and perspective for handling a curricular area that earlier went under such varied names as general knowledge, social studies, general science, nature knowledge/study, citizenship education for the young, and others.

Most plants comprise roots, stems, leaves, blossoms and buds, and deliver natural products containing seeds. Potato is a Stem. Potato is considered as a stem vegetable because it grows in underground stems, known as stolons. Potato tubers are considered to be thick stems that have the buds sprouting stems and leaves.

If Harpreet wants to give suggestions to her students on how to contribute in the best possible way towards environmental protection, then, in that case, she should suggest them to use the public transport system for travelling because firstly it will reduce air and noise pollution. Due to the rising number of personal vehicles air and noise pollution has increased and secondly, this will lessen the burden of fossil fuels and cause less protection.
Hence, the correct answer is, 'Use public transport system for travelling.'

• An oil field is a place that is used for the purpose of extraction of petroleum products such as crude oil or natural gas.
• There are two types of oil fields: offshore and onshore oil fields.

Explanation :

• West Bengal has its own oil Field "Ashoknagar Oil Field".
• Bombay High is an offshore oilfield 176 km off the west coast of Mumbai. 
• Assam has a worldwide famous oil field Digoboi. 
• Gujarat has two famous oil fields Kalol and Ankleshwar. 

Thus, Chhattisgarh, Odisha, and Delhi are the only states/UT which do not have oil fields.

For class III students, showing a video film on animals will be the best way to introduce the topic as the students enjoy watching movies related to animals. Students believe what they watch. The still pictures of animals won't do as good as showing a video film.

Traditional occupation is an occupation where the work is carried on generation after generation by the people of the family and asking students to discuss occupations that their ancestors did is an appropriate activity.  
Hence, the correct answer is "Asking students coming from this background to narrate about it".

Field trip refers to the learning approach which ensures the active involvement of students in the learning process by taking them to a certain place where they can earn knowledge by engaging with real situations.
Here, taking students on a field trip for plant study will make them able to:

• identify a few of the familiar plants by their name.
• observe and record the differences in plants based on their external features.
• classify leaves based on their shape, size, and patterns.
• identify the seeds and fruits of the plant, based on their shape and size.
• appreciate and value the existing beauty and diversity of nature.

Hence, we can conclude that an EVS teacher is planning to take students on a field trip for plant study as he/she wants to make students able to identify and classify different leaves based on their external features.

Mawsynram is a small town in the East Khasi Hills of Meghalaya in North-East India, 65 kilometres from Shillong. It is the wettest spot on Earth, with a normal yearly precipitation of 11,872 millimetres.

To promote the concept of conservation of trees some activities can be fruitful such as:
(I) Encouraging every student to adopt a tree and look after it.
(II) Organizing a debate on forest conservation.
(III) Organizing a poster making competition on trees
But, showing children the storage of logs of wood will not have any positive impact on the children instead it will have an adverse effect on cutting trees.
Hence, the correct statement is, 'IV'.

The Lesson Plan refers to the outline of the lesson prepared by the teacher to bring forward the lesson in a coherent way. It starts with introductory questions to activate the learner's previous knowledge and connects the new knowledge with the previous one. 
Learning Objectives of Teaching Living and Non-Living:

• Students will be able to define and give examples of man-made and natural things.
• Students could tell the characteristics of living and non-living things. 
• Students will differentiate between living and non-living things.
• Collect some living and non-living things from their school/home environment
• Draw the line diagram of some living and non-living things

Hence, we conclude that all the above points are learning objectives of teaching living and non-living.

Demography is the measurable investigation of population, including that of individuals.

As she is considered a very creative person, she is learning a concept by divergent thinking. Divergent thinking is recognized as a thought process that is used to generate creative ideas by exploring many possible solutions. It typically happens in a spontaneous, free-flowing, "non-linear" manner, such that many ideas are generated in an emergent cognitive fashion.
Hence, the correct answer is, 'Divergent thinking.'

• Kids are very sensitive and aware of the way they are responded to.
• A kid can tell about different kinds of touches.
• Touches can be good or bad.
• Children should know it’s ok to say no even if it’s a family member or friend.

Good touch:

• A touch that makes a child feel secure, cared for and happy.
• Safe (good) touches feel caring, like pats on the back or wanted hugs.
• For example, a mother hugging a child or a grandparent kissing their child or a doctor examining a child.
• Any touch that makes the child happy or secure is a good touch.

Bad touch:

• A touch that makes a child uncomfortable, afraid or nervous is a bad touch.
• Unsafe (or bad) touches hurt your body or feelings, such as pinching or hitting.
• The child will not feel safe with a bad touch.
• For example, if an adult touches your child and tells him or her not to tell anyone, or if your child feels very uncomfortable when kissed or touched, then it’s a bad touch.

All the given are the methods to teach EVS, except 'explaining through lectures' because the things performed practically will be clearer and more understandable.

Malaria parasites are often identified by examining under the microscope a drop of the patient's blood, opened up as a “blood smear” on a slide. Prior to the examination, the specimen is stained (most often with the Giemsa stain) to offer the parasites a particular appearance. 
Hence, Malaria can be detected by testing the blood for the presence of Plasmodium in red blood cells.

Environmental Studies learning objectives include cognitive, affective, and psychomotor behavior, therefore multiple assessment techniques are needed for evaluating the outcomes.

• Therefore, the teacher must recognize practical tools and techniques for recording significant information for the assessment of learning and for learning. 

Plants release oxygen in the presence of sunlight.
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Baking means to cook food by dry heat without direct exposure to a flame it can be typically in the oven, then frying means cooking food in oil it can be typically in shallow pans, and Roasting means cooking food in an oven or in an open fire. All these are methods to cook food.
Hence, the correct answer is, 'Baking, Frying, Roasting'.

The study of the environment in relation to the earth and living beings is known as environmental studies.

Stories and poems are not intended to give a break off from monotonous content, or to change a routine. They are intended to promote imagination in students, help them develop interest in the subject, and make the content more enjoyable and easy to learn.

Scavengers are the animals that feed on other dead animals. Scavengers play a very important role in our environment. They help in removing the dead and decaying material from the the the Earth surface, they also help up in the process of decomposition. Few examples of scavengers are vulture among birds and earthworms, ants, flies, etc. 
Hence, the correct answer is "Scavengers".

Environmental Studies is a subject that is concerned with the development of learners' awareness of environmental issues. It nurtures children's curiosity about the natural environment.

• Teaching-learning at the primary stage should be environment oriented, child-centered, and activity-based. Educational activities ensure the growth of learners' knowledge and assess their level of understanding.
