Things We Make and Do Questions and Answers

Answer: B

Burning fuels gives heat and light energy.

Burning (combustion) is a chemical reaction in which a fuel combines with oxygen and releases the energy stored in it, mainly as heat and usually also as light, as in a flame from wood, kerosene, LPG or a candle.

Burning does not give only light. Mechanical energy is obtained only when heat is converted in an engine, and sound is at most a minor by-product, so heat and light together is the correct answer.

Answer: A

Bronze is made from tin and copper.

Bronze is an alloy mainly of copper with tin, usually about 88 percent copper and 12 percent tin. It is harder than copper and resists corrosion, which is why it was used for tools, weapons and statues from the Bronze Age onwards, as in the bronze dancing girl from Mohenjo-daro and Chola bronzes.

Copper and zinc make brass, the common confusion. Aluminium and zinc, and zinc and tin, are not the components of bronze.

Answer: A

The tool is the Illige.

This comes from NCERT's Class 4 EVS lesson about Basva, whose family grows onions in Belvanika village in Karnataka. After the harvest, his mother and aunt use the sharp illige to cut the dried leaves from the top of the onions.

The other tools appear in the same lesson for other jobs: the kurige is pulled by bullocks to sow the seeds, and the khunti is used in preparing the field. An ordinary knife is not the tool the lesson names.

Answer: C

Pochampalli is now a part of Telangana.

Bhoodan Pochampally, in Yadadri Bhuvanagiri district, is known for its ikat weaving, in which the threads are tie-dyed before weaving so that the pattern appears in the cloth. The weave received a Geographical Indication tag. The town was in Andhra Pradesh until Telangana was formed in June 2014, which is why the question says 'now'.

Karnataka, Kerala and Tamil Nadu are other southern states with their own famous textiles (Mysore silk, Kasavu, Kanchipuram silk), but Pochampalli belongs to none of them.

Answer: A

The objectives are (a), (b) and (d).

The paper-weaving activity lets children explore colours and patterns and develop an aesthetic sense (a), connect what they do with the work of weavers, which is the point of the theme 'Work We Do' (b), and practise choosing materials and cutting strips carefully, building fine motor skills (d).

Memorising the steps of making a mat (c) is rote learning, which does not fit an activity-based EVS lesson, so every option including (c) is wrong.

Answer: D

Pochampalli is a part of Telangana.

Pochampally, in the Yadadri Bhuvanagiri district of Telangana, is famous for its ikat sarees, in which the yarn is tie-dyed in patterns before weaving, giving bright geometric designs; the weave itself is called Pochampally and has a Geographical Indication tag. It was part of Andhra Pradesh until Telangana was formed in 2014.

Tamil Nadu is known for Kanchipuram silk, Karnataka for Mysore silk and Maharashtra for Paithani sarees.

Answer: A

The skills involved are Questioning, Expression, Inferring.

Visiting farms, students ask farmers about implements and crops (questioning), draw conclusions from what they see and hear, such as how crops relate to soil or season (inferring), and present their findings in a report with photographs (expression).

The task involves no experimentation, hypothesis or prediction, so the other three sets of skills do not describe it.
