A standard unit refers to a definite magnitude that is taken as a standard for measuring physical quantities.

#### Page No 115:

The SI unit of mass is kilogram (kg).
The SI unit of length is metre (m).
The SI unit of time is second (s).

#### Page No 115:

It is advisable to take an average of three readings while making scientific measurements, as it minimises the chances of error.

Galileo discovered that a swinging pendulum completes one oscillation in a fixed amount of time. This triggered the invention of a pendulum clock.

#### Page No 115:

It is an inaccurate way of measuring, as different people have different body proportions that alter the sizes.

#### Page No 115:

Beam balance is an instrument which is used for measuring the mass of an object.

#### Page No 115:

A pendulum refers to a weight that is suspended from a fixed point, so that it can swing freely.

Babylonians gave us hours and minutes by dividing a day into 24 hours, and an hour into 60 minutes.

Following are the three points that we should keep in mind while measuring length using a ruler:

1. The ruler must be placed parallel to the object whose length is being measured.
2. Eyes should be kept exactly above the point where the measurement is being taken.
3. The 'zero' mark should be avoided if the ends of the ruler are worn out.

People realised the need of measuring length, as they needed to measure the distances between two places. They also wanted to measure different objects with a standard unit so that the measurement is acceptable to everyone.

#### Page No 115:

In case we have a broken ruler, we can use the remaining markings, corresponding to one end of its length, to measure any object. After obtaining the measurement, we have to subtract this reading from the reading corresponding to the other end of the length of the ruler that is broken.

Take some pins and fix them vertically on the curved line wherever the edge of the object changes its direction. Tie a knot on a thread at one end of the object. Pierce a pin through this knot and fix it at one end of the curved edge. Stretch the thread along the pins and get it marked with a pen where it touches the last pin. Measure the length of the thread from its knot to its other end by stretching it along a ruler. This gives an approximate length of the curved line.

To measure the length of a curved line using a divider, open the legs of the divider by taking the distance between the pointed ends as 0.5 cm. Place the pointed end of one leg at one end of the line and the other pointed leg along the line. Rotate the first leg around the second leg and place it further along the line. Keep on repeating this until one leg of the divider touches the end of the line. Count the number of times you placed the divider along the curved line and multiply it by 0.5 cm. The product will give you the actual length of the curved line.

1. Every measurement has two parts-a number and a unit.
2. A kilometre is 1000 times a metre.
3. Your eyes must be exactly above the point where you are making the measurement.
4. The length of the elbow to the tip of the middle finger is a cubit.
5. What metre is to length, second is to time.
6. What a pan is to a beam balance, a balance wheel is to a fine spring.
