At night, when you look up high in the sky, you will notice trillions of shining dots, out of which some appear brighter, some are bigger while some of them twinkle. It is a point to ponder, what are these bright dots? So they are nothing but stars and planets. Stars are heavenly bodies that possess their own light and twinkle. They are fixed and large luminous body like the Sun. On the flip side, planets are celestial objects, which have an apparent motion of their own and also moves around … [Read more...]

The way, we handle wastes has a great impact on the global environment, i.e. our ecosystem. In our school life, all of us have been taught an eco-friendly 'mantra', with the help of which wastes can be managed or disposed off effectively, with least harm to the environment. The rule is, Reduce, Reuse and Recycle, often known as 3R's. While reuse implies using the same item or natural resource, again and again, recycle alludes to the transformation of waste item to a useful one. Most of the … [Read more...]

The process of thinking about something, in a rational manner, so as to draw valid conclusions, is known as Reasoning. It is a daily activity that we use to make decisions, which involves the construction of thoughts and converting them into a proposition to give reasons on why we have opted for a particular alternative over the other.Reasoning (logic) can take two forms - inductive reasoning or deductive reasoning. The inductive reasoning follows a particular flow or behaviour so as to make … [Read more...]

In our day to day life, we came across a number of three-dimensional (3-D) objects, which has a certain volume. The volume of a substance is the total amount of space that it covers, i.e. when we measure the space region taken up by a solid object it is called as volume. Conversely, Capacity alludes to the quantity of something that a container holds. In short, capacity is the container's volume. Due to many similarities, the volume is often confused with capacity, but there are less but … [Read more...]

Each and everything that surrounds us and we are using in our day to day life is either discovered or invented, by experts. Most people have a misconception regarding the words discovery and invention, due to which they end up with the supposition that these two are one and the same thing. But that is not true, as discovery means uncovering something, which already existed, but not recognised by anybody else before, i.e. finding something unexpected. On the other hand, the invention refers to … [Read more...]

The hypothesis is the fundamental instrument in conducting research. It proposes new experiments and observations and indeed most of the experiments are undertaken, with the sole aim of testing the hypothesis. It is a propounded explanation for the happening of a particular phenomenon, whose development is based on specific evidence. Due to insufficient knowledge, many misconstrue hypothesis for prediction, which is wrong, as these two are entirely different. Prediction is forecasting of … [Read more...]

In our daily life, we encounter many changes in our surroundings, though we do not notice them, such as souring of milk, rusting of iron, stretching of a rubber band, bread becoming toast, melting of wax, liting of a match, etc. All these changes that take place around us are physical change or chemical change. Physical changes are the changes that change the physical traits of the substance, without making any change in their internal structure. On the other hand, a chemical change is one … [Read more...]

Everything that surrounds us is either living or non-living and the only characteristic that bifurcates the two is life. All living things like plants, animals, insects, birds, microorganisms, etc. have one feature in common and that's life. So, living things implies all those creatures of nature, that has life. On the other hand, non-living things such as bottle, pen, chair, door, computer, mobiles, etc. are the one's who are not alive. Living things are composed of units called cells, which … [Read more...]

Everything that surrounds us, such as air, food, water, plants, animals, vehicles, clothes and so forth is made up of matter. The matter is a collection of particles and is anything that has mass and occupies space. There are three fundamental states of matter, i.e. solid, liquid and gas. The states of matter take place due to the variations in the molecules of matter. The size and shape of a solid object is definite. Nevertheless, if we talk about the other two states of matter, that is … [Read more...]

Energy implies as the object's capability to perform work. It is something that cannot be created or destroyed but can only be transformed. An object loses its energy, when it performs work, whereas it gains energy when the work is performed on it. Energy is broadly classified as kinetic energy and potential energy. While kinetic energy is the energy which an object contains because of a particular motion. On the other hand, potential energy is the stored energy, because of its state of rest. … [Read more...]
