Question
State the procedures for the measurement of length using a metre scale.
✓
Answer
While measuring length using a metre scale, we must follow the steps given below:
$1.$ The ruler should be kept along the length of the object so that the zero mark on the ruler coincides with the one end of the object. The ruler should be parallel to one of the edges.
$2.$ While taking the measurement, the eyes should be correctly positioned. The eye must be exactly vertically above the point where the measurement is to be taken.
$3.$ If the edge of the ruler is worn out or broken, the measurement should be taken from any other full mark of the ruler.

Activity.
Collect samples of vinegar, lemon juice, mustard oil or coconut oil, kerosene or any other liquid. Take a glass tumbler. Fill it up to half with water. Add a few spoonfuls of one liquid to this and stir it well. Let it stand for five minutes. Observe whether the liquid mixes with water (see figure). Repeat the same with other liquids, as many different liquids as are available to you. Write your observations in Table.
