The tradition of bee-keeping in Bihar is very old. The period of October to December is considered as the best to start bee-keeping because at that time number of flowering and crop plants is more. So bees will get nectar and pollen easily to increase the production of honey. There was a setback to the bee-keeping industry in the 1980s due to the disease caused by the Thai sacbrood virus.
Hence, the correct answer is, 'October to December.'

Thus, S1 is true and S2 is false

The atmosphere of Earth consists of different layers of gases encompassing the planet Earth that is held by Earth's gravity. The climate ensures life on Earth by retaining bright sun-based radiation, warming the surface through warmth maintenance, and lessening temperature extremes in the middle of day and night.

Quality of nutrition, culture and quality of education are the environmental factors that shape the development of a child. The physique of a child is not developed due to an environmental factor. Environmental factors are all those external agents that influence the growth and development of an individual. The study of environmental influences on human physical growth and development has focused on the influences of social and economic factors, family and household characteristics, urbanization/modernization and nutrition.
Hence, the correct answer is, 'Physique.'

Liquid water evaporates into water vapour, condenses to form clouds, and precipitates back to earth in the form of rain and snow.
The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.
Effects of the water cycle:

• It regulates the temperature of the surroundings.
• It changes to weather and creates rain.
• It helps in the conversion of rocks to soil.
• It circulates important minerals through the spheres.

Giving importance to individual experiences of children in an EVS class will benefit the teacher to connect the subject to the learners' experiential world and promote reflection and learning.

A Shooting star is a Meteorid that catches fire as it enters the Earth's atmosphere. A shooting star is a piece of rock or metal that burns very brightly when it enters the Earth's atmosphere from space. From the Earth, it looks like a bright star, which travels very fast across the sky.
Hence, the correct answer is, 'Meteorid which catches fire as it enters the Earth's atmosphere.'

The word experiment comes from a Latin word meaning ‘to try’ or ‘to put to test’. An experiment usually helps to establish a cause-effect relationship. It includes enquiry, observation, inferring and testing of a hypothesis. It is not difficult to devise experiments that can generally be fitted within the time allocated to teach a particular topic.

• The teacher may need to do preparations in advance
• You may not be able to have every child do the experiment, you may need to involve many children as observers
• While several experiments can be done by children in the classroom/at home, some experiments may require equipments and/or laboratory facilities 

Hence, we conclude that all the above points are correct in the context of challenges of experiment method.

Temperature is constantly measured taking into account the solidifying and breaking points of water. In 1948, the Centigrade scale renamed it the "Celsius" temperature scale and most nations utilize the Celsius scale.

Vultures are carrion-eating raptors.
Hence, the correct answer is, 'Kites, Eagles, Vultures.'

A variety of resources are available around you. You as a creative EVS teacher, need to develop the ability to identify and use them effectively. Such resources can be broadly categorised as follows:
Community Resources:
The belief that ‘each person is important’ can be very meaningful in this work. Practical work leads to knowledge construction. Thus Day-to-day work experience makes every person an expert. Thus skilled workers like a gardener, an iron smith or even a carpenter can become very useful resource for you. Now you will be able to list many such names as a resource, like iron smith, goldsmith, gardener. Look at how resourceful can a teacher become by using the expertise of the local community members.

• Nirmala’s father, a farmer, has been invited by her teacher to help children understand better about plants in general and weeds in particular. 
• Just as the local heath worker is able to help in understanding the human body, as well as health and hygiene related topics, the local patwaari or revenue official is an expert both on maps and local history.
• Avinash, a carpenter on his way back home from the city, supports you as teacher in your class on measurements, something he is an expert at. And when he is not available, then you ask the local tailor to help you out.

Thus it is clear that the teacher is using community resources. 

Environmental factors that shape the development of a child include all of the following, except physique, because it can not impact the working level or the performance of the student.

Photosynthesis is a process through which green plants make their food in sunlight, water, and air. Blue colour boosts the electrons of chlorophyll for higher levels of energy in the presence of blue light. 
Hence, the correct answer is "Blue".

At the primary level, children must be taught through an integrated approach rather than teaching in parts.
