Example: V -> 5.   You might have also seen Clocks that use these Roman Numbers like these in the picture below: Roman Number Symbols: We can easily write the numbers if we know and understand the following symbols and what they stand for. The Rules: If a symbol is before a  larger symbol then they are  subtracted . Eg: IX = X - I = 10 - 1 = 9 If a symbol is after a  larger symbol then they are added .  Eg:  CXX  =  C  +  X  +  X  = 100 + 10 + 10 =  120 We also have a Mnemonic for this, which is A fter Larger is A dded.

States of Matter - Introduction

Image
  Hey kids! Welcome back to KidsCast! Today, we are going to discuss the different States of Matter, in our environment! So let us begin! What are States of Matter?  Everyday, in all of our environment, we see various things. Some of them are hard, some of them are soft, some of them are wet and some of them are dry. All these characteristics or features like "soft, wet, hard, and dry" have proper names for the State or Features of its Matter. So, states of matter can be said as the forms or states in which matter exists. States of Matter can also be said as the different forms of matter. Matter in simple terms means anything which has mass and which does take space. So let us learn more about the States of Matter!  What are Molecules? Before we study about the States of Matter, we first need to know that what are Molecules. Molecules are the smallest unit of a material, or a compound.

Respiration In Plants - Plants breathe too!

Image
Hello Everyone!  Welcome to another article! Today Let's learn about Respiration In Plants! During the day plants take in Carbon Dioxide for photosynthesis and release energy and oxygen. However, at night they inhale oxygen and breathe out Carbon Dioxide. Ever wondered how they do that? Let's learn about it today!   RESPIRATION THROUGH LEAVES Stomatas are special structure present on the underside of the leaves of the plant that help in exchange of gases. Its Opening and Closing is brought about special cells known as Guard Cells. The opening and closing happens due to variation is light and moisture. RESPIRATION THROUGH ROOTS Did you know that roots also breathe. They absorb the oxygen from airspaces prsent between the soil particles. Hence we say not to overwater the plants as water may displace the air spaces and effect the growth of the plants. RESPIRATION THORUGH STEM Trees having hard and woody stems the respiration also occurs through the stem. There are pores on the ba...

The answer is that it is a kind of energy which is created by vibrations. When there is a movement in an object, the air particles present all around us start moving creating vibrations and further creating sound which we hear through our ears, but, do you all know that this movement is so fast that we don't even get to know about the process. Speed of Sound But why don't we get to know about the process? This is because sound travels really fast. The movement is so fast that it does not let us get to know what exactly happened.  Sound travels differently in solids, liquids and gases.  According to scientific te...

The Generations of Computers - KidsCast!

Image
Hello Everyone! Welcome to KidsCast! In today's post, we will be discussing about The Generations of Computers. There are 5 Generations of Computers . These computers used different types of Computer Languages. The languages used in First and Second Generations of  Computers are examples of Low Level Languages.  The languages used in the Third, Fourth and Fifth  Generations of Computers are examples of High Level  Languages. First Generation: The period of the First Generation of Computers were from 1946 to 1959.  These computers used Vacuum Tubes or Thermionic Valve Machine.  The First Generation Computers used a language called Machine Language.  The input of this system was based on punched cards and paper tape , the output was  displayed on printouts. Examples of these Computers: ENIAC, EDVAC, etc. Second Generation: The period of the Second Generation Computers were  from 1956 to 1963.  The Second Generation Computers us...
