Activities and Experimentation Questions and Answers

Answer: D

The most appropriate response is to conduct and observe the experiment with different amounts of salt.

In inquiry-based EVS, the teacher does not hand over the explanation but helps children find it. Repeating the experiment with different amounts of salt lets them see that the egg sinks in plain water, floats once enough salt is dissolved, and that more salt makes it float higher. From these observations they can work out that salt makes the water denser, so that it supports the egg.

Telling children that the egg floats due to the density of water gives a term without understanding, and putting off the answer to higher classes discourages enquiry. Letting children add different items at random loses the focus on salt that the experiment is about.

Answer: C

The most appropriate activity is developing an EVS kit from available material.

Hands-on activities let children learn by doing: handling, making and experimenting. Making an EVS kit from local, low-cost materials involves collecting, sorting, constructing and using objects, so children are actively engaged and learn to see their surroundings as a resource.

Map reading from a globe and drawing plant parts on a chart are largely visual and paper-based. Collecting foreign coins is a hobby, depends on access to such coins, and has little to do with EVS learning.

Answer: D

(A) is true, but (R) is false.

Field trips are an effective pedagogical strategy in EVS, because they let children observe the environment first hand, ask questions, collect information and connect classroom learning to real places and people.

The reason is false: the value of a field trip lies in observation, exploration and understanding, not in memorising objects, events and places. Promoting rote memorisation is exactly what EVS pedagogy tries to move away from.

Answer: B

The most appropriate strategy is a Project.

The task asks children to find out how much water was available in their parents' and grandparents' time, collect this information over some days, and compare it with today. That is an extended, open-ended inquiry with several steps: planning, gathering information from family members, recording, comparing and drawing conclusions. Such multi-step investigations are what EVS projects are for.

Talking to elders, an interview, is one of the methods the children would use within the project, but on its own it does not cover the comparison and conclusion. Role play and classroom discussion do not involve collecting the information at all.

Answer: C

The answer is (A), (B) and (C).

Explaining the rules before kabaddi connects the game with the lesson's ideas about rules in life. Rules let everyone play fairly and the game run properly (B). They show children that, as in sports, we make rules in life too (A). And in society we are all bound by rules in the same way, which is how we settle differences and conflicts (C).

Statement (D) is not a reason a teacher would give. Rules are explained so that the game can be played fairly, not to make children attend more to the rules than to the game. Every option containing (D) is therefore wrong.

Answer: C

The most appropriate purpose is that at the primary stage, children learn better by interacting with each other.

The activity is built around group work: children collect objects together, discuss them and agree on how to sort them. Sharing observations, explaining their reasons and hearing other children's ideas is how young children build concepts such as properties and classification, which is the social-constructivist view behind EVS teaching.

The activity is not meant to favour the cognitive domain over others; it involves social, physical and emotional engagement too. No single activity develops understanding of 'all the concepts', and its aim is understanding through exploration, not avoiding mistakes in definitions and facts.

Answer: D

The teacher should do (B) and (C).

The children's question is a chance for inquiry. The teacher should give each child the freedom to observe, record and interpret their own observations (B), and the opportunity to guess why things float or sink, test those guesses with more objects and arrive at activity-based generalisations (C). This is how children construct understanding in EVS.

Simply telling them it is 'because of density' (A) hands over a term they do not yet understand and ends the inquiry. Saying they will understand in higher classes (D) dismisses their curiosity. Options containing (A) or (D) are therefore not the most appropriate.

Answer: D

The option that is not relevant is 'It helped the community understand the diseases that they suffered from'.

The survey is a teaching-learning strategy for the children. Its value lies in what it does for their learning: they interact with the community, connect what they learn with real life, handle data, and work together in groups.

A children's survey asks people questions; it does not set out to educate the community about its diseases, so that outcome is not a purpose of the strategy.

Answer: D

The answer is All of the above.

An EVS classroom uses many kinds of activity. Picture reading asks children to observe, describe and interpret pictures; field visits take learning out to the real environment; and the blackboard is used for activities such as drawing, listing children's ideas or making tables with them.

Since each of the three can be an activity in EVS teaching-learning, the option that includes all of them is the key's answer.

Answer: D

The objectives are A, B and C: creativity, observation and design skills, and aesthetic sense.

When children observe animals carefully and then draw them in their own way, they sharpen their observation, practise representing what they see (design), express themselves creatively and develop a sense of beauty and form.

Each of the narrower options picks only one or two of these outcomes, while the activity serves all three.
