00:00what will we learn we will learn about the following concepts in this lesson measuring
00:18length measuring mass measuring capacity measuring time measuring temperature let's get started
00:30hey shivani look i think i am taller than you no i am taller than you i don't believe that let's go and ask
00:41mummy about this okay then let's go and ask her mommy yes children what happened mommy shivani is
00:53saying that she is taller than me but i believe i am taller oh let's see to this we will measure your
01:02height and see who is taller mummy what does measure mean measure means to find the size quantity
01:12or degree of something also measurement refers to the process of finding the size quantity or degree
01:21of something but mummy what is high and how can we measure it height is the vertical length length is
01:31the measure of something from one end to another it tells us how long an object is
01:39we can measure length in different ways in earlier times people measured lengths with their hands and
01:48feet wow but how did they do it they used to measure lengths in arm length which is the length between
01:58the shoulder and the second finger foot span is the distance covered by one foot step hand span is the
02:08length between the tip of the thumb and the little finger cubit is the distance from the elbow to the tip of the
02:18the second finger that's so amazing yes but we do not get accurate measurements using body parts because the size of
02:30body parts differ from one person to another therefore we need to have a standard unit of measurement what is
02:40the standard unit of length the standard unit of length is meter some other units for measuring lengths are
02:50centimeter millimeter and kilometer a ruler a meter rod or a measuring tape can be used to measure length
03:01length oh now i understand meter centimeter and kilometer are some standard units of length while arm length
03:13cubit and hand span are some non-standard units of length well done shivani you are absolutely correct
03:23come now let's measure your height
03:29well both of you are of the same height shivani your height is 128 centimeters and aryan your height is also
03:40128 centimeters oh that means none of us is taller than the other yes my dear you are right
03:52mommy what are the other things that we can measure we can measure mass capacity
04:01temperature and time as well wow it's interesting to know this please tell us more about this mommy
04:12of course dear we will talk about the other units of measurement tomorrow okay mommy we should complete our
04:20home work now
