MAHA TET Paper 1: Environmental Studies Test - 7 - MAHA TET MCQ

Use of fertilizers is affecting the natural biogeochemical cycle. Overharvesting is directly affecting the ecology by reducing the population of greeneries. With the introduction of non-native species, production in native species has been decreased.

EVS stands for Environmental Studies. Though EVS is a multidisciplinary approach that is linked with many subjects yet mostly it deals with the surroundings. It makes students aware of their surroundings. It makes students aware of how to conserve the resources and do not waste them because they are limited in quantity.
Hence, the correct answer is, 'Environmental Studies.'

The teaching of EVS also helps students to develop desirable attitudes, values, and behavior patterns necessary for an environment-friendly lifestyle.

One Pashmina shawl is considered as warm as 6 normal sweaters and it takes 250 hours to weave a plain Pashmina shawl. The weaving is a laborious process. A single Kashmir Pashmina shawl comprises fine hand needle embroidery which takes a long time to complete. The handwork is unique for each artisan and the weaving cannot be passed from one artisan to another. It is very thin yet very warm. 
Hence, the correct answer is, '06; 250.'

The animals that live mostly on trees are referred to as arboreal animals. Monkeys, parrots, chameleons, etc. are examples of arboreal animals. 

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 (protection and conservation).

• EVS curriculum has been created using a child-centered approach to themes that provide a common interface of issues in social studies, science, and environmental education.

The teacher has not explained or elaborated anything regarding the activities. So, this is the correct answer.

Rina has separated the garbage into biodegradable and non-biodegradable waste.
Biodegradable waste is a waste that degrades or breaks down naturally. For eg- plants, animals, their waste, paper, fruits, flowers, vegetables. Som Banana skin, vegetable peels, dried leaves and newspapers come under biodegradable materials.
Non-biodegradable waste is a waste that cannot degrade or break down naturally. For eg- rubber, plastic, chemicals, paint plastic, etc. So, Jam bottles, Sauce bottles, used toothpaste tubes, plastic toys come under non-biodegradable materials.
Hence, the correct answer is, 'can be decomposed/ cannot be decomposed.'

The activity-based program includes various activities that involve the active participation of the child and makes their learning stronger.

Important Points
Sahil wants to organize the activity to introduce the topic “Nutrition” to her class V students. He should ask the students to open their tiffin boxes, see the contents, followed by her explanations.

All the options suitably describe a planet.

Formative Assessment is also termed as Assessment For Learning. It is conducted by the teachers to encourage students to remain active in their learning. The suitable methods can be explaining the definitions of important terms given in the lesson, perform the given practical activity and record observations, draw labeled diagrams of the given experimental set-up. Discussing the disadvantages of water pollution is not a suitable Formative Assessment task in EVS.
Hence, the correct answer is, 'Discuss disadvantages of water pollution.'

Coriander is a heavily consumed herb plant.

• Herbs generally refer to the leafy green or flowering parts of a plant.
• Herbs are plants with savoury or aromatic properties.
• They are used for flavouring and garnishing food, for medicinal purposes, or for fragrances.

Rose is an example of Shrub

• A shrub is a small- to medium-sized perennial woody plant.
• Unlike herbaceous plants, shrubs have persistent woody stems above the ground.
• Shrubs can be deciduous or evergreen.
• They are also called bushes.
• Other examples- China rose, lemon.

Peas are climbers.

• Stems that attach themselves to nearby objects by means of some special devices like hooks, tendrils are known as climbers.
• A climber is any plant with a growth habit of climbing.
• The climbers are plants that can get off the ground on their own.
• They need some kind of support in place, whether natural (such as a tree) or artificial.
• Creepers don't get off the ground.

​They are generally considered to be small, plants that grow close to the ground.

The students are curious in nature. They observe things and ask a number of questions to satisfy their curiosity. Educational trips give educational experience to the students away from their regular school environment. The students observe new things which fascinate them, and share their observations with their friends and teachers. This is what is expected from them after they return from a trip.

Hands-on activities assessment and oral testing are the best pairs of techniques that are likely to be more objective assessments. Home assignment assessment and project work assessment would not be of greater help as many times the parents of the children prepare the projects without giving proper knowledge to the children. So this kind of project would not be of any help.
Hence, the correct answer is "I and IV".

A science exhibition is an event where science projects created by students are exhibited to an audience that includes teachers, parents, and judges.
Objectives of organizing a science exhibition at the primary level are -

• To create a learning environment for education.
• To develop creativity amongst the students.
• To develop a scientific attitude among the students.
• To encourage them to involve in using their potential and creativity in developing something.

Hence we conclude that organizing a science exhibition at the primary level is to create a learning environment for education.

The soil's capacity to hold water is unequivocally identified with the molecule size; the firmness to hold water by fine particles of clay soil is more than the coarser particles of a sandy soil or loam, so clay holds more water. Conversely, sands or loams give less demanding transmission of water through the profile.

The section on 'Survey and Write' in some chapters of the EVS textbook for Class V primarily aims at providing the opportunity for students to explore and learn. This is the best method of learning, learning by doing. In this method whatever the children have learned they can practically implement by exploring so that they gain a better understanding of the concepts. Hence, the correct answer is, 'Providing opportunity to students to explore and learn.'

Environmental studies are the study of the environment in the context of earth and living things. It includes the study of humans with other aspects affecting their life.

• It is more concerned with the scientific attitude to explore, investigate, and develop an understanding of our natural, human, social and cultural dimensions of local and wider environments. It also studies how humans can contribute positively to bring the desired changes in our environment.

India's awesome pioneer Mohandas Gandhi broadly said that there is enough on Earth for everybody's need, but not enough for everybody's greed.

Bronze is recognized as an alloy of copper and tin which was used in making big guns (cannons) that are found in the fort of Golconda. Some common uses of Bronze are based on its resistance to corrosion, including saltwater and its lubricity (slickness), it also includes bearings for machinery, marine propellers,  statuary and fitments for boats. 
Hence, the correct answer is, 'Bronze is an alloy of copper and tin.'

• Sunlight (Solar energy) – Non-Conventional.
• Tidal Energy – Non-Conventional.
• Geothermal energy - Non-Conventional.
• Fossil Fuels - Conventional.

Fossil Fuels:

• Fossil fuels are formed by natural processes such as anaerobic decomposition of buried organisms under heat and pressure.
• Some exhaustible natural resources like coal, petroleum and natural gas are formed from the dead remains of living organisms (fossils) so, these are all known as fossil fuels.
• Fossil fuels are non-renewable conventional resources and must be burned to release their energy.
• It releases sulphur, nitrogen, carbon, etc. gases in the atmosphere which causes the greenhouse effect and pollution.

The primary objective of taking students to an outdoor trip is to co-relate the classroom teaching to real life situations. This is the correct answer.

A lemon sinks in normal water but floats in salty water because the density of salty water is more than the density of normal water. This is due to the amount of salt added into the water which makes it denser.
Hence, the correct answer is, 'Salt water is more than normal water.'

Assessment is a process of collecting relevant information on student learning. It is one of the crucial components of the teaching-learning process. Assessment does more than just measuring learning. 

Experience itself teaches the teacher with in-depth knowledge of his subject. Hence, he needs to prepare only a brief outline of what he teaches.

The capital of Himachal Pradesh (Shimla) and the capital of Madhya Pradesh (Bhopal) are located in North and South with respect to the location of Delhi on the map of India.
Hence, the correct answer is North and South.

The desirable outcome of learning experiences - the way individuals are to act, think or feel as a result of participating in some instructional activities - can be classified into three domains, viz. Cognitive, Affective, and Psychomotor.

• Bloom and his associates classified educational behavior from the simple to the complex, based on the level of learning, they developed a taxonomy of learning outcomes.

Grouping is an activity to make students learn to cooperate with each other. So, the teacher must form groups in such a way that all the members participate and cooperate with each other.

Compost is the organic matter that has been formed with a mixture of dead-decayed plants and animals. It provides fertility to the soil. It does not have chemicals present in it and is very helpful in the growth of the plants. 
Hence, the correct answer is "Compost".
