Bihar STET Paper 1 Science Mock Test - 3 - Bihar PGT/TGT/PRT MCQ

Solar, energy, wind energy, geothermal energy are some of the non - exhaustible non - polluting sources of energy. These energy sources are environmental friendly. For example - wind energy can be captured through wind mills for irrigating fields as well as generating electricity power  . So, option ( b) is correct one.

Statement (i) and (ii) are correct because manure is prepared from the break- down of plant and animal waste products. Hence it is  rich in organic matter. Manure contributes to the fertility of the soil by adding organic - matter and some essential nutrients like N, P and K which helps in enhancing growth of plants.  Manure makes the clayey soil aerated  because of their small - pores and increase the water holding capacity of the sandy soil due to their large pore size.  . In clayey soils, the large quantities of organic matter help in drainage and in avoiding water logging. . In clayey soils, the large quantities of organic matter help in drainage and in avoiding water logging.

Heat energy is conducted by transferring energy of atoms vibrating at high level. This energy is transferred by vibrating neighboring atom. Since high density of mercury, there is no enough room for vibrating mercury atoms. So it can’t be heated easily.

As metal carbonates react with acid, a neutralisation reaction happens. Salt, water, and carbon dioxide are produced. This can be expressed in the following general equation:

metal carbonate + acid → salt + water + carbon dioxide

The least compressible state of matter is solid form. 

Solids have much more connected bonds or forces between their own atoms. Since their atoms are more tightly packed together, closer to one another, and are stronger bonds than liquids and gases, then they require more energy (more compression) to change the structure of their atoms. 

The Law of Octave was found to be applicable upto calcium as after that every eighth element did not possess properties of the first element.

Lignin is the complex polymeric molecule composed of Phenylpropanoid units associated with cellulose ( as Lignocellulose) in cell walls of Sclerenchyma, Xylem vessels are tracheids, making them strong and rigid. After cellulose, lignin is the most abundant plant polymer, forming 20-30% of the wood of the trees.

Acetic acid gives a pleasant smell on rejection with ethanol due to the formation of ethyl acetate as :- 
CH₃COOH  +C₂H₅OH → CH3COOC₂H₅ +H₂O

The correct answer is B as Volkmann's canals are small channels in bone that transmit blood vessels from the periosteum into the bone and that lie perpendicular to and communicate with the Haversian canals. It is named after Volkmann Alfred Wilhelm. It is only found in bones of mammals. Hence, option C is correct.

A drop of ink spreads in a beaker of water through diffusion. This is because the particles in liquids can move around each other, which means that eventually they are evenly mixed. Diffusion is the process of a substance spreading out to evenly fill its container or environment. In a solution, a concentrated solute diffuses to spread evenly in its solvent. concentration to low concentration. 

Source of vast energy of the Sun is the nuclear fusion of four hydrogen nuclei into a single helium nucleus going on at the centre of Sun. In the process an extraordinarily large amount of energy is released which is the energy radiated by the Sun.

Plants absorb water from the soil by osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis. The absorbed water is transported through the roots to the rest of the plant where it is used for different purposes: It is a reactant used in photosynthesis.

NEP 2020 aims to achieve a Gross Enrollment Ratio (GER) of 50% in higher education by 2035.

The greatest cause of failure of a new teacher is in the area of interpersonal relations. If the teacher is not able to develop a bond or relationship with the students, she will be rejected by the students and will face a lot of hardships.

Indian education structure and management were guided by New Education Policy, of 1986 for a long time (almost 34 years). In the meantime, a lot of changes have taken place globally as well as a debate has also emerged in India about a ‘Bharat-centric’ policy on education.

• In order to look into those, a new committee was set up under the chairmanship of Dr. K. Kasturirangan in June 2017. After reviewing the suggestions, the committee finalized the policy under the name National Education Policy, 2020 on July 29, 2020. 

Key Points

Major recommendations of the policy were -

• The aim of equity and inclusion is now at the heart of the new NEP so the classroom should be inclusive.
• Ensuring universal access at all levels of schooling from pre-primary school to Grade 12.
• Ensuring quality early childhood care and education for all children between 3-6 years.
• New Curricular and Pedagogical Structure (5+3+3+4)including foundational, preparatory, middle, and secondary.
• Establishing National Mission on Foundational Literacy and Numeracy.
• Emphasis on promoting multilingualism and Indian languages. 
• Exposure to vocational education in school and higher education system.
• Focus on Formative and Diagnostic Assessment.
• Setting up multidisciplinary education and research universities(MERUs).
• Setting up of National Research Foundation(NRF).
• Multidisciplinary approach and focus on creative and divergent thinking.
• Experiential learning using previous knowledge and experiences.
• Teacher Education - 4-year integrated stage-specific, subject-specific Bachelor of Education.

Hence, it is concluded that all the above options are correct.

Mr. Rathore uses a lot of audio-visual aids while teaching. The main reason for doing so is to take care of the requirements of all the children. Audio-visual aids make the learning permanent. They stimulate both aural and visual senses of children. Some children understand better on observation i.e. visual, whereas other students understand better on aural stimulation. Thus, requirements of all the students are taken care of.

Inclusive Education means education for all children in school as It refers to the inclusion of all children in the education system, regardless of their differences and disabilities.

• It values the diversity, each child brings to the classroom and facilitates all with equal opportunities to learn and grow.
• Inclusive education improves the quality and making provisions of education for all. >Inclusive education welcomes and celebrates diversity.
• It provides a provision to include disabled children along with normal children in a regular classroom environment.
• It refers to an education system that accommodates all children regardless of their physical, intellectual, social, emotional, linguistic, or other conditions.

Key Points

Basic Principles of Inclusive Education:

• Equity and equal opportunities for all.
• Well constructed educational plan.
• Use of multilingualism as a resource.
• Use of specific pedagogical strategies.
• Sensitization towards individual differences.

Important Points

Institutional initiative for inclusive education can be evidenced when :

• Time is provided for teams of teachers and paraprofessionals to plan together
• A differentiated curriculum is designed
• School provides students to explore different co-curricular activities as per their interests.

Additional Information

• Entry-level tests to enroll students should not be supported according to NCF
• School should have differentiated material for all students
• Instead of common assessments, assessments as per the need of learners should be conducted.

Hence, we can say that institutional initiative for inclusive education can be evidenced when time is provided for teams of teachers and paraprofessionals to plan together.

The term used interchangeably with 'Motivation' is 'Need'. 
Motivation is a term that means the motive behind something. It means a person wants something, has a desire for something, wants to avoid something, and wants to escape from something. Having a desire for something is related to need. When we need something, then only a desire creates to have that thing.
Thus, this is the correct answer.

Visual Impairment: The term 'visual impairment' is used to refer to not only those who are blind but also those who have their own vision. When the person has residual vision above a certain level, he is said to have low vision or poor vision. However, if the residual vision is below that level, he is considered to be blind.

Important Points

In a classroom situation, the total number of blind students should be 10-12, so that teacher can adopt the strategies which cater individual differences in the class.

Strategies to teach blind students in the classroom:

• Teachers who teach blind children in ordinary classrooms need to provide adequate special materials and equipment. There is almost universal agreement that the special materials and equipment needed by a visually impaired student in a regular school are essential to success.
• In addition, Friendly user materials are good teaching materials for blind children, and creative materials which are provided to blind children enhance dialogue and social interaction to complete an assignment. 
• Students with visual impairments who's knowledge of concepts are strong would have difficulty keeping pace with this rate of instruction unless it is entirely verbal.
• Purposeful sampling was used to select teachers who teach blind children in ordinary classrooms. Legibility for teacher’s participation in the study was based on the following criteria:
  • experience in teaching blind children with their distance vision assessment results indicating that they are blind with (visual acuity of (3/60 or worse).
  • Teaching ordinary classrooms,
  • fully attending school at the time of the study, and
  • gender balance was desirable but not necessary.
• The teacher who is guiding the blind children in ordinary classrooms is supposed to know more than the blind pupils who are being guided, that is why very many blind children have fallen victims to wrong teaching. Guidance is needed for blind children since they can hear, it is easy for them to learn.

Hence, we can conclude that in a classroom situation, the total number of blind students should be 10-12.

In the triarchic theory, three types of intelligence proposed by Robert Sternberg are: Analytical, Creative and Practical.

The Indian Space Research Organisation (ISRO) is set to launch the European Space Agency's (ESA) Solar Study Mission Proba-3, highlighting ISRO's role as a key player in international space collaborations and missions.

The Varuna naval exercise is a biennial exercise between the Indian Navy and the French Navy. The 21st edition of the exercise, Varuna-23, was held in the Arabian Sea in September 2023. Phase II of the exercise was held from September 6 to 9, 2023.

River Ganga passes through Uttarakhand, Uttar Pradesh, Bihar, Jharkhand and West Bengal. So, it need not be crossed while travelling from New Delhi to Chennai.

Radiation effects are also classified in two other ways, namely somatic and genetic effects. Somatic effects appear in the exposed person. The delayed somatic effects have a potential for the development of cancer and cataracts. Acute somatic effects of radiation include skin burns, vomiting, hair loss, temporary sterility or subfertility in men, and blood changes. Chronic somatic effects include the development of eye cataracts and cancers. The second class of effects, namely genetic or heritable effects, appears in the future generations of the exposed person as a result of radiation damage to the reproductive cells.

As we know the formula,

Let AB be the light house and the two boats be at C and D

∴ AB = 125 m

tan30° = BC/AB = x/125 = 1/3

=> x = 72.17 m

tan45° = BD/AB = y/125 = 1

=> y = 125 m

∴ The distance between the two boats is = x + y

= 72.17 + 125

= 197.17 m

Given: Neptune, Planet, Moon

The logic followed here is: Neptune is a Planet, but Moon is not. Moon is a natural satellite.

Hence, option (4)  is the correct answer.

The family chart is as follows:

i) A is brother of B
ii) B is brother of C
iii) C is husband of D
iv) E is father of A
Drawing the family tree as per the given information:

Thus we can see D is the Daughter - in - law of E.
Hence, the correct answer is "Daughter - in - law".
