INTRODUCTION

Analogy

Word Analogy means correspondence, in other words connection between two things or resemblance of one object to another in certain aspects.’

An analogy is a comparison in which an idea or a thing is compared to another thing that is quite different from it. It aims at explaining that idea or thing by comparing it to something that is familiar.

The questions on Analogy tests a candidate’s knowledge, power of reasoning.In these a particular relationship is given and another similar relationship has to be identified from the alternatives provided. There can be various kinds of relationship like instrument and measurement, part and whole, individual and group, worker and product.

TYPE 1 : COMPLETING THE ANALOGOUS PAIR

In this type of question, two related words are given. Another word is also given.The candidate is required to find out the relationship between the first two words and choose the word from the given alternatives, which has the same relationship to the third word, as the first two words have.

Ex. 1. Bombay : Maharashtra : : Trivandrum : ?

(a) Calcutta (b) Gujrat (c) Rajasthan (d) Kerala (e) Sikkim

Sol. This question is about state and its capital. Bombay is the capital of Maharashtra. Similarly, Trivandrum is the capital of Kerala. So, the answer is (d).

Ex. 2. Cattle : Herd :: Sheep : ?

(a) Flock (b) Swarm (c) Crowd (d) Shoal (e) Mob

Sol. This question is about group and individual. Herd is a group of cattle. Similarly, flock is a collection of sheep. So, the answer is (a).

TYPE 2 : SIMPLE ANALOGY

Doctor is related to Patient in the same way as Lawyer is related to ?…..

(a) Customer (b) Accused (c) Magistrate (d) Client

Sol: Here first works for the second. Just like a doctor works for his patient, a lawyer works for his client.

Needle is related to Thread in the same way as Pen is related to …..

(a) Ink (b) Cap (c) Paper (d) Word

Sol: Here second is inserted in the first. Just like a thread is inserted into a needle, ink is inserted in a pen.

TYPE 3 : CHOOSING THE ANALOGOUS PAIR

Chalk : Blackboard

(a) Type : Paint (b) Table : Chair (c) Ink : Paper (d) Door : Handle

Sol . Just as chalk is used to write on a blackboard, so also ink is used to write on a paper. Hence, the answer is (c).

Train : Track

(a)Idea : Brain (b) Water : Boat (c) Bullet : Barrel (d) Fame : Television

Sol: A train moves on tracks. Similarly, a bullet travels through the barrel of the gun.

QUIZ TIME: Lets take a quiz to test your understanding.👇 👇

FUN ACTIVITY: Sixteen Soldiers

BOARD

An expanded Alquerque board is used. Two triangle boards are attached to two opposite sides of an Alquerque board. Each player has 16 pieces that are distinguishable from the other player. Pieces are placed on the intersections (or “points”) of the board, specifically on their half of the Alquerque board, and the nearest triangular board.

RULES

The following rules are based upon Parker’s description:

Players alternate their turns
A player may only use one of their pieces in a turn, and must either make a move or perform a capture but not both.
A piece may move onto any vacant adjacent point along a line.
A piece may capture an opposing piece by the short leap as in draughts or Alquerque. The piece must be adjacent to the opposing piece, and leap over it onto a vacant point immediately beyond. The leap must be in a straight line and follow the pattern on the board. Captures are not mandatory. A piece can continue to capture within the same turn, and may stop capturing any time. The captured piece (or pieces) is removed from the board.
The player who captures all of the other player’s pieces wins.

If you need any help to understand the game follow the link below:

Homemade water xylophone

You will need

Water
Food coloring (we used blue, yellow and green for varying shades of green)
Wooden sticks (we used bamboo skewers or pencils)
4+ jars (preferably glass jars)

Use any object you want to hit the glass bottles or jars to make noise. We used a butter knife and wooden stick.

WHAT ACTUALLY HAPPENS

More water equals lower sound or pitch and less water equals a higher sound or pitch. When you tap the empty jars or glasses, they all made the same sound. Adding different amounts of water changes the noise, sound, or pitch.What did you notice about the amounts of water versus the sound or pitch that was created? The more water, the lower the pitch! The less water, the higher the pitch! Sound waves are vibrations that travel through the medium which in this case is water! When you change the amount of water in the jars or glasses, you also change the sound waves .Sound is simply vibrations that move through a medium that our brains interpret into noise we hear. When a glass is tapped with a spoon the vibrations travel from the glass to the water, then through the air to our ears. It all happens so quickly!

NOW TRY THIS –

Try adjusting the water levels to create new sounds.
Try using different liquids and compare results. Different liquids have different densities and the sound waves will travel differently through them. Fill two jars the same amount but with two different liquids and observe the differences! ( like oil and water or milk and oil )
Try using different tools for tapping the glasses. Can you tell the difference between the wood chopstick and a metal butter knife?
