Mnemonics Science Class X Chemistry
When we want to learn a new piece of information and remember it, we can associate it with something we always remember. By doing so we remember the new information and it is stored in the old slot.
Class X Chemistry NCERT
For example to remember the technical names for the single, double or triple covalent bonds, we can associate them with the alphabetical order that is familiar to us.
Single bond alkanes
Double bond alkenes
Triple bond alkynes
The beginning is same for all three - alk
The end is the same for all three - nes
The letter after 'alk' is different in each word.
Alkanes - a (after alk - and before nes)
Alkenes - e
Alkynes - y
In the alphabetical order a comes first, e next and then y is the last.
Hence it is easy to remember
Alkanes - Single bond
Alkenes - Double bond
Alkynes - Triple bond
At the time of examination if under stress we forget things such simple tricks can save us.
Mnemonics For Scoring Better in Examinations
For examinations and tests we may need to commit to our memory some bits of information in any subject. Mnemonics can help us mainly to remember lists of words and order of things. Mnemonics are memory devices that improve our memory to remember details especially in the form of lists like the atomic value of elements, the order of adjectives, characteristics, steps, stages, parts, etc. How do we use Mnemonics? If we have a list of words to remember in the same order, we take out the first letters of each of the words and make a sentence that we can easily remember. For Example, learners of Class X need to learn a list the Reactivity Series, which is a list of metals arranged in the order of their decreasing activities.
Here is the list of Activity Series: Relative reactivities of metals
Reactivity Series
Learners need to remember this list of metals in the same order. The Mnemonic trick that we can use here is to take the first letter of each word and create a sentence that they can commit to memory easily.
The first letters are: P S C M A Z I L H C M S G
Mnemonic sentences are easy to remember if they are woven around a specific theme, if they are unique and unusual and if they bring a picture in front of the mind's eye.
One example sentence here could be:
Princess Sophia calculates maths adding zeroes in LCM HCF covering mainly silver and gold.
If learners are able to remember this sentence and associate the P of princess with the P of Potassium and S of Sophia with the S of Sodium and so on they can easily recall this list in the same order.
Composition of Atoms of the First Eighteen Elements with Electron Distribution in Various Shells
If Class X learners need to learn the first 18 elements and their atomic values they can use Mnemonic tricks.
Composition of Atoms of the first 18 Elements If we take the first letters we will get H for Hydrogen, H for Helium and so on. Taking all these letters we can try to create a sentence for ourselves. Here is a sample sentence: Have her light brown blue candles at night Over flashy neon streetlight, make all sleep peacefully, soon children awake If learners memorise this sentence and then try to link the first H with Hydrogen, the second H with Helium, Lithium with the L of light etc. they can easily remember the order. The atomic numbers 1 to 18 can be easily remembered. Since the number of protons and electrons remain the same, they only have to learn a few calculations to learn the whole table. In the same way if the learners want to know the order of adjectives in a sentence, they can use Mnemonics. English
Order of Adjectives The order or adjectives in a sentence has the following pattern: Opinion, Size, Physical quality, Shape, Age, Color, Origin, Material, Type, Purpose
The first letters are OSPSACOMTP Now let us try to create a sentence with words starting with these letters. They can be any words but when we read the sentence it should make a visual impact that remains in our memory for a longer time. Mnemonic Sentence: Oh! Spiderman paints sky and clouds orange mountain tops pink
Example sentence using multiple adjectives: She is a beautiful, tall, thin, young, black-haired, Indian woman. The sentence we make for Mnemonics should be memorable and create a picture in front of our mind's eye. Then alone we can remember it for a long time. It is also important to associate the beginning of each word in the Mnemonic sentence with the original words they stand for. Computers
Let's try it for one more subject. In computers you may need to remember the following and know which is bigger than which one.
KMGTP - these are the first letters. So we can make a sentence like
Keep, moving gadgets tied properly.
We can imagine the gadgets running away and someone advising us to keep them tied properly.
We can visualize this image in our mind. We should not forget to relate K to Kilobyte, M to megabyte and so on.
We can also create Mnemonics in our own languages.
கஞ்சகருமி மொட்டமண்டை குண்டு தக்காளி பூசணிக்காய்
कल मंडप गिरके टूट पड़ा
The beginning sounds of these words are KMGTP
Try to use this Mnemonic trick for whatever you want to remember. Social Studies Class X Federalism In Social Studies which includes History, Civics and Geography, learners need to remember bits of information. At the time of examination they get confused because all the different information they commit to memory get into a chaotic pattern. The examination stress adds to the confusion. Hence some examples are given here to create Mnemonic bits that are easy to store and retrieve. This does not disregard the higher level understanding of the content learners are expected to acquire. Different tiers of government govern the same citizens, but each tier has its own JURISDICTION in specific matters of legislation, taxation and administration. A - administration L - Legislation T - Taxation Jurisdiction Alt - Administration, Legislation, Taxation The first route involves independent States coming together on their own to form a bigger unit, so that by pooling sovereignty and retaining identity they can increase their security. This type of ‘coming together’ federations include the USA, Switzerland and Australia. U - USA S - Switzerland A - Australia Coming together federation USA USA - USA, Switzerland, Australia The second route is where a large country decides to divide its power between the constituent States and the national government. India, Spain and Belgium are examples of this kind of ‘holding together’ federations. S - Spain B - Belgium I - India SBI is easy for Indian students to remember as it stands for State Bank of India. Holding together federation - SBI SBI - Spain, Belgium, India Union List includes subjects of national importance such as defence of the country, foreign affairs, banking, communications and currency. They are included in this list because we need a uniform policy on these matters throughout the country. The Union Government alone can make laws relating to the subjects mentioned in the Union List. B - Banking C - Communications C - Currency D - Defence F - Foreign affairs Union List BCCDF (according to alphabetical order) Banking, Communications, Currency, Defence, Foreign affairs State List contains subjects of State and local importance such as police, trade, commerce, agriculture and irrigation. The State Governments alone can make laws relating to the subjects mentioned in the State List. C - Commerce A - Agriculture P - Police I - Irrigation T - Trade State List CAP IT - Commerce, Agriculture, Police, Irrigation, Trade Concurrent List includes subjects of common interest to both the Union Government as well as the State Governments, such as education, forest, trade unions, marriage, adoption and succession. Both the Union as well as the State Governments can make laws on the subjects mentioned in this list. Edu - Education For - Forest Tr - Trade unions A - Adoption M - Marriage S - Succession Concurrent List EduforTrams - Education, Forest, Trade unions, Adoption, Marriage, Succession Chemistry Bingo

To play Bingo for any subjects we can select the words, prepare clues as per the definitions or related info, or whatever the learners have to know for examination purposes. Then we can ask the learners to prepare the Bingo columns using their notebooks or sheets of paper. Or we can print out the Bingo boards and distribute.
Write the list of words on the bb or white board. Ask the learners to copy the words in any order in their bingo board. Call out the clues prepared in advance and ask the learners to mark the words on their bingo. Ask them to call out if they finish one row or the full house.
The purpose of the game is to help them learn for their examination in a stress free, fun way. So after playing once you can give them the clues as well as words, ask them to learn it and play the game again as a whole class or in smaller groups.
Encourage the learners to play the game as homework or in free periods for fun. .We can also assign homework for the learners to prepare their own bingo games.

Suratiology
Yesterday slipping from the so called reality has become an entry in the memory diary
to refer to if and when I decide to do so
Today is speedily following the trodden path
making way for the so called unknown future
A moment of stillness in this study of kinesiology
can lift me up to the true reality within me
metamorphosing the horizontal timeline to vertical horizons
The study of Suratiology has a tough entrance test
I need to join the coaching class of a Super Power
paying a heavy fee with my body and mind
Escalator
Going up and down as I please
Looking around with no real purpose
Moving with the flow from time immemorial
Repeatedly returning to starting point
I contacted a cool current of peace
That has picked me up to drop me beyond space!
Training
The preparatory training to board this spaceship is to sit still
Do nothing but just sit still
within and without
The Koel in my garden has perfected it
It is free of the latest technology that tampers with the training!
Watching Kulfi Kumar Bajewala
The fictitious facts of life fill my time whisking away my waking worrying hours What little is left of this lifetime achievement I am filling with fiction of frivolous minds where evil is entertaining and everlasting and any and all nonsense makes super sense in terms of twists and turns and TRP rates
