Since the time Earth developed the quality of sustaining life, life has always gone under the process of evolution. Life started from single celled organisms and developed stage by stage. One organism extinct to develop into its better developed species or even at times it happens that some animals get erased from the surface of the earth due to extreme environmental condition.

EXTINCT ANIMALS: Species of animals which existed in the surface of the earth once upon a time but has no current existence, this may have been a result of extreme environmental condition or some other condition for existence. For example, we have dinosaurs, Dodo.

ENDANGERED ANIMALS: The species of animals which have only a few animals left on the surface of the earth and are in the mouth of being extinct are known as endangered, currently this is a result of poaching i.e., unethical killing of wild animals with purpose or change in the climate due to pollution and other factors. For example, we have the Royal Bengal Tiger.

We cannot do anything for the species which are extinct but we can definitely take steps and save our endangered species. Poaching laws should be made stricter and it should be taken care that people follow them.

Tuition classes are the extra class which a student takes apart from the classes of school or any institute to for better understanding of subject and topic and also students who are slow learner gets a lot of benefits from these tuition classes. But everything comes with its own advantages and disadvantages so does tuition classes so let’s see a few of them:

ADVANTAGES:

1. Students develop a better understanding and also does get a chance to revise things and practice more.

2. Students develop skills and grow their knowledge on the particular subject, as because these acts as booster classes and there as there are no pressure of syllabus so both students and teachers get a chance to explore and study the subjects and topics in greater depth.

3. It allows the students to feel free and ask as many doubts as they want as it does not have any time constraint.

Disadvantages:

1. Many students get indulged with friends and other attractions and thus do not utilize the time and opportunity properly in studying.

2. A lot of time gets invested in the journey to and from these classes.

3. Many times, both students and teachers do not consider it seriously and as a result the whole time and effort goes into vain.

In the world we find varied geographical regions which includes mountains, plains, deserts, plateaus all with their own physical features. Desert is basically a piece of barren land which is filled with sand and lacks water bodies and have dry weather all along. In day time deserts are extremely heated up and at night it becomes chilling cold at the same place. In the Indian subcontinent we find desert in the western part of the subcontinent in the state of Rajasthan.

The animals and plants in the deserts have their own adaptations, among plants we find a variety of cactus, cactus plants have special adaptations to survive in the desert, they have fleshy stem which holds water in them which turns out to be useful when there is scarcity of water also they have very long roots which can penetrate deep inside the soil in search of water also they don’t have leaves and have thorns in place of them in cactus the food is prepared in the step as it contains chlorophyll and is green in color. Also, we find camel in desert their feet have adaptation to walk on the sand also they can survive with less water and they have long eyelashes to protect their eyes from dust storms.

Summer is the brightest season on this earth, after the chilling winter the warmth of the sun soothes its living beings. But this same summer makes life a bit difficult in the tropical regions when the temperature crosses 50-degree Celsius and the earth almost burns in the scorching heat of the sun. But as always nature plays its game smartly not only it gives us the scorching heat and its disadvantages but simultaneously it also gives us the way to deal with it, the various fruits and vegetables which grow in summers to provide us the potential to withstand the heat are also provided.

In summers we get to eat the king of all fruits i.e., mango which almost all of us loves also we find many fruits such as watermelon, cucumber, litchi, black berry, pineapple one thing which is common to the fruits and vegetables available in summers is that their water content is high, also they at times give some cooling effect which helps us to relax. Talking about the flowers we mostly see flowers ranging in white color much in summers which have very pleasant smell and this smell also somewhere helps us to deal with the heat.

Our atmosphere consists of many layers one such layer is the ozone layer this layer protects all the living beings from the harmful ultraviolet rays of the sun. The chemical formula of ozone is O₃, When the UV radiation of the sun interacts with the molecular oxygen (O₂) it splits some of them into free oxygen atoms (O) these free oxygen atoms react with the molecular oxygen to form ozone (O₃) and thus build a layer of protection on us. But recently due to over pollution on the earth’s surface caused due to various human activities a hole has been observed above the continent Antarctica, this in turn lets the harmful ultraviolet rays of the sun to reach the Earth’s surface and thus is causing many fatal skin problems including the life taking skin cancer.

The depletion of the ozone layer is an issue of outmost concern, and it is found that the element which is primely there behind this is CFC (Chloro Fluro Carbon), CFC molecules are emitted from refrigerators and Air- conditioners which are used in every house these days, also it is present in various sprays which we use on a regular basis. The increase in the number of such products will result in more depletion and thus would result in a dangerous situation. Its high time for us to replace these machineries with other technology.

A good educational background acts as a spinal cord for all of us to stand up-right in the society and walk on the path of success. A strong educational background always holds some strong points in every interview or anywhere where someone needs to showcase educational qualification. Education is a basic primary necessity as well as a right to which every individual must have access to. Education gives us knowledge and brings us to light from the darkness of superstition and other wrong things. Education shows direction to people it also helps us to develop ourselves in terms of technology as well as moral values. Studying and getting educated is a very important part of all of our lives and is not a one-day task. A strong educational background also increases depth of knowledge and lets one think rationally and people do not get to take advantage of such people easily as they have a lot of teachings and experience in themselves, also a person with strong educational background will inspire others as they know the value of education and people willingly, also a person with strong educational background will inspire others as they know the value of education and people willingly will follow their footsteps as their see them to be successful in life. Ultimately most of our goal in life is to become successful and this strong educational background plays a major role in making one successful in life.

We human beings are the one who is responsible for polluting our nature and thus in turn nature also takes its revenge through various calamities, diseases, pandemic and so on. We all know that pollution is mainly caused by non-biodegradable wastes and plastic is such a non-biodegradable product which we human beings use very frequently in our everyday life, starting from plastic bags to toys, containers, food packaging almost everything has the use of plastic in it and thus is also generates a lot of waste daily. Plastic being a non-biodegradable waste stays into the soil or water for years and does not decompose rather they choke animal and water creatures also restricts plant growth and leads even to their death sometimes when the roots get entangled into them. Non-biodegradable plastic waste if burnt emits toxic fumes which in turn causes severe air pollution and is extremely harmful for living beings. We have got so much use of plastic that we cannot completely stop the use of plastic we can reduce it to some extent. To save the nature and environment from pollution we can follow the 3R’s i.e., Reduce, Reuse and Recycle. Recycling plastic is a great method which is even sustainable and can help us save our nature.

Different ways of teaching students effectively especially in this pandemic situation which can even be continued in future for effective studies.

Teachers
need to find new technology of smart teaching and should incorporate smart
animations, classroom assignments which will even be helpful to evaluate
the students.
Technology
should be used in such a way to design the practice materials so that it
ensures that students should not engage in some unethical means to get
grades.
More
efforts are to be given on evaluation, teachers should go around and bring
out innovative ways to judge a student and practical knowledge should be
praised more than bookish knowledge.
Teachers
and student both should take care of the network connectivity and in case
a student is from a rural place where network facilities cannot be
exercised for them the institute should prepare recorded lectures and
hardcopy of notes and ensure that it reaches the student in time.
Self-
awareness must be spread amongst the students and they should be explained
the importance of education to them as they are the future generation to
carry forward the human race.
Teachers
should encourage interaction in class; this will help the teacher-student
bond to grow and will upgrade the quality of the class, switching on the
web cams of the students should also be enforced this will help with more engagement.
Students
should ensure that they engage themselves with active responding skills
because without response it really becomes difficult for the teacher to
move on.

Our nature consists of the green trees, plants, various animals, humans and even the non-living elements such as air, water, soil together all these constitutes of the nature in which we live in. But recently human development adversely affects the nature and toxifies it through pollution. But things cannot go this way if it continues soon our nature and environment will become unworthy to sustain life, thus we need to take steps to conserve our nature and natural resources. Steps which we can take in order to conserve our nature are:

1. Deforestation is the practice of cutting down of trees for human needs, we need to reduce this practice as it reduces the oxygen supply in the environment, it is also the major cause of soil erosion also.

2. We should engage and more into planting trees as it will increase the greenery, improve the oxygen supply, regulate the rain cycle and meet other human needs.

3. We should use more of public transport or try to walk or cycle to nearby destinations, this will reduce the emission of fossil fuels.

4. Waste materials before being dumped into soil or water bodies should undergo treatment.

5. The use of air conditioners should either be reduced or replaced as they emit CFC’s which is very harmful for the nature.

Any Motion that repeats itself at a regular interval of time on the same path is known as Periodic Motion.

Oscillation refers to any Periodic Motion moving at a distance about the equilibrium position and repeats itself over and over for a period of time.

Simple Harmonic Motion (SHM) is a Periodic motion in which the acceleration of the particle is directly proportional to its displacement from the mean position of rest and is always directed towards the equilibrium.

In ideal case, an oscillator should keep oscillating for infinite time span.

Because the total energy is conserved. A damped oscillation is an oscillation in which the amplitude fades away with time. It happens due to the presence of opposing force or the

retarding force such as friction.

Example of oscillations can be very easily seen in our everyday lives as like the movement of the pendulum of the clock represents oscillation, a guitar string which produces music also oscillates.

Examinations are basically a path of judgement of the theoretical knowledge which a student possesses in their growing ages or while accomplishing a certain training. Examinations are important to judge the academic part of a student but it is not he only criteria. Often, we tend to judge students only on the basis of their report cards and thus it turns out that the judgement was not fair enough. But examinations are outmost necessary because when a person knows the theory or the working formula behind a particular thing then only, he/she will be able to do hands on that particular field. Conducting exams builds a discipline among the students and helps them to stick towards a particular routine which is very important for the student community. But the fact must be ensured that examinations are conducted in a fair manner from both the sides of the students and the teachers. Also, the results of the examinations help a student to understand where one belongs, the area which requires improvement and also gives them the statistics of improvement over a period of time.

Our immune system is the one which helps us fight various diseases and thus keeps us healthy and fit so that we can do whatever we are supposed to. It is very important that we take care of the fact that we are not nutrient deficit and take good care of our immune system. Ways to boost our immune system:

1. We should consume healthy nutritious food rather than junk. Healthy food ensures that we are not nutrient deficit and also provides with the various requirements of our body.

2. We should exercise regularly to keep ourselves fit; physical health also plays a key role in boosting our immune system.

3. Practicing yoga helps us build concentration and keeps us away from negativity and also regulates the flow oxygen in body.

4. Water is the universal fluid we must make sure that we consume enough water to ourselves hydrated and fresh.

5. Stress gives a very bad impact on immune system we should take care that we take less stress and do not unnecessarily worry on things.

6. Another important factor is that our body should get rid of its metabolic wastes regularly, for that we must ensure roughage in our diet thus this also helps.

Time is often called the fourth dimension though it is not yet scientifically proven, but time is the most powerful and the costliest thing in this world. Time has the power to heal it can even heal the deepest wounds and time is the greatest treasure one has. Time possesses the power to turn the best time into worst and even the worst into best. Time when utilized properly with enough of efforts and productivity can yield the best of fruits and can even turn out to be a game changer. In this busy world what we all lack is time, we all to some extent can devote our belongings, money but giving out time to someone may turn out really costly and we often do not give time on thing we know would yield no result.

One should value time and understand its real worth. Procrastinating is a very bad habit which takes away times and gives you nothing in return. Thus we can conclude that time is really money due to its own worth.

Nowadays we come across a lot of packaged food, juices and whatnot and this food comes very hand in the hour of need, thanks to the various preservation and conservation techniques that today we can even have biriyani and many other delicate delicious dishes just by following a few basic steps. Also, one of the all-time saviors which has the highest position in conserved food is ready to eat noodles all we need to do is to put some warm water into the packaging and wait and within minutes our delicious noodle is ready to eat and enjoy.

Some of the basic elements which are used to conserve food are vinegar, oil, as well as there are various chemicals which and synthetic substances which are used to do the same. Conserving food is a great technique it lets us have food which are not even of that season also it gets us access to the taste of food which is not found at a particular place and needs to be imported from foreign at such a situation there is a very high chance that the food will get spoilt but the technique of conservation of food here gets our back.
